Re: The fusible link thread
I am looking for the same solution for the 2.0 FL.. Had the exact same response from 2 National Automotive shops, the Advanced Auto freaks and the 10th century parts guy at Toyota. "Dumbfounded"... Side note -bought the 1.25b FL through Toyota today for $26.84, 1-2 day shipping..

Re: The fusible link thread
Great to hear that you found it. I have not had any issues with the dash lights or charging system since I replaced both fuses near the battery. Not too far from you in Columbia, SC. Good luck !

Re: The fusible link thread
Nolo - My local auto parts store had short (10-12") 12g FL wire in blister packs, I used about 6in with crimp and shrink connectors (ring terminal at battery, butt terminal where it meets the harness)
No issues since.
Hope it helps

Re: The fusible link thread
So the amperage of the 2.0 is 80A and you can simply straight wire without an actual fuse, just the FL wire? Can you post a photo here of that set up? I'm not very electrically inclined..
-
Re: The fusible link thread
Found 7 foot pieces of 12 Guage FL Wire for a replacement of the 2.0 FL at NAPA and runs about $1 per foot. I think I have figured it all out at this point and I thank you all for your imput. It has been tremendously helpful.
Big props to Tim in Portland! Keep it weird and keep it wired!

Re: The fusible link thread
What can I replace these fusible links with if Toyota links arent available? Best substitutions?
-
Re: The fusible link thread
The FL1.25B and it's holder are still available from Toyota as is the yellow main fuse.
As they are still available, its the easiest route to go (and not overly expensive and they "fit" without having to re-engineer anything).
The other 2 are NLS, but the solutions are all contained within the post you have quoted.
(Pico or weather-pack fuse holder with a 15A ATO fuse and 6in of 12G fusible link wire, both are sold at most auto-parts stores)

Re: The fusible link thread
Ok here we go:?:! I changed my fusible links and checked all connectors...tried to start and checked for codes. The engine light blinks 3 times then stops and 3 again several times. Assuming the code is 3! Would any issues with cap, rotor, wires or coil cause this or is it a cut and dry issue with ignitor?:dizzy::dizzy::pissed:

Re: The fusible link thread
Rivvy - Now that you have your links sorted, perhaps this discussion would be better addressed on your other thread?

My flashing dash lights ended up being a half-burnt ignition fuse. Although my van is totally different than yours so it's a long shot. Worth checking though.

Re: The fusible link thread
What happens if you run it with the headlights fusible link removed? I assume the obvious in that the headlights won't work, but is anything else affected?
I have a short somewhere in my headlight system and it goes away only when I remove that fusible link. So I am curious if I can run my rig during the day with the FL out and not have my battery drained...
Anyone have any idea?
Thanks and happy holidays😃

am1 fuse replacement?
hey guys, so i started getting an occasional clicking when trying to start my van (1986 2wd 5spd) and saw a lot of corrosion on the battery terminals so i decided to go through all the fusible links/battery terminals etc. when i got to the am1 fuse, it looked like the previous owner had tried to remove it with a hammer. blindfolded. it was all beat up and cracked, and the clear cover on the top was missing. the fuse was still intact, but so green with corrosion that i figure id be crazy to not change it.
Attachment 4967
i pulled it out, and took it to the parts store and the guy behind the counter said they didnt carry fuses like it and that he had never seen one before...is it a special fuse only available through toyota maybe? is it special because its a "fusible link" and not a fuse? If anybody could share a link of where i can find one if it isnt a specialty toyota fuse, that would be excellent! ive done a fair amount of searching but couldnt find anything that looks similar

Re: am1 fuse replacement?
Not sure about the aftermarket but easily available at your friendly neighbourhood Toyo dealer.
It was used in many different models over the years, you shouldn't have any trouble locating something.

Re: The fusible link thread
Howdy folks!:wave1:
So some recent problems with my 87 4WD van. First the headlights went completely out. After searching, replacing stuff (even swapped out the main fuse block!), testing, etc...found the cause to be a blown Fusible Link behind the power steering reservoir. Replaced that...all is well....for a little bit anyway. Driving to Oly the other night with the headlights on, chillin', cruisin' and all of a sudden everything shuts OFF! Dash lights, head lights, engine...ALL OFF! Traced the problem to my AM1 Fusible Link. The van is killing these things one by one! With no tools or spare fuse, had the van towed home....luckily I wasn't far.
Off to the parts vans I go. Both had the fusible links still. I replace the AM1, van started but when I turned on the headlights, the van wanted to die. After playing with this a few minutes, the van died and blew the headlight AND EFI FL. WHAT?! :cnfsd: After inspecting, I'm finding the van has/had some fairly corroded Fusible Links. I replaced the blown ones with the best ones I had and now turning on the headlights isn't an issue and the van seems ok. I want to keep spare Fusible Links in my vans. Having problems finding them online... are they NLA? Anyone have part numbers for these? I looked at the online FSM and didn't find part numbers. I'd like to have at least 3 sets of each. Picture below of what I'm looking for...any info is appreciated.

Re: The fusible link thread
How do you pull the AM1 fuse, i was able to pull out the first 3 and couldn't figure out how to get that last one?
Thank you
JDM
-
Re: The fusible link thread
Hey JDM! The AM1 fuse is attached with screws. There are two bolts holding the block up, just loosen them and slide the block out. You'll see the wires attached with screws. You can either use a screwdriver or a socket (8MM?) to get the screws loose. Took me a while and a busted up Fusible Link to figure this out. :dance2:

Re: The fusible link thread
thought i'd pass along some potentially valuable info related to fusible link trouble shooting:
only had this van a few months. it runs and drives great. but i noticed when it was wet and rainy van would start and run rough. a few times (only when it was pouring rain) engine completely lost power and shut off. after it dried out van started up fine and drives fine.
i replaced distributor cap / cap seal, rotor, spark plugs and plug wires.
i also covered the 1.25B fusible link with an aluminum sheath.
no more problems! even when van has sat in the rain for days and driven in pouring wet conditions.
i can't say for sure covering the fusible link in an aluminum sheath was the only fix but it seems like a good idea to help keep off water and dirt etc. some people say a thin coat of dielectric grease on the FL might help.
i used these aluminum take-out boxes 3 for a dollar at the dollar store which i cut and bent to shape. also made a shield over the alternator with same material. maybe i'll make something a little more permanant later.

Re: The fusible link thread
The 60A AM1 FL has been superseded by an 80A fuse Toyota part #90982-08203. I believe the #PAL180 will work here too (and that should be readily available at most auto parts stores. Tim

Re: The fusible link thread
The FL 0.5G fusible link appears to be missing from my battery compartment:
Attachment 5173
I traced the wire and if i followed it right it runs to the + junction box. is that short green section thats been spliced in a fusible link? Should I worry about this or does this look acceptable?
Attachment 5174
-
Re: The fusible link thread
There was a 1.5" section of thin solid core wire coming from the harness to my battery (+) where FL 0.5G should be. I put in a weather resistant fuse holder and 15 amp ATO fuse like Tim suggested.

Re: The fusible link thread
what does the FL1.25B do exactly? What circuit is it on and what would symptoms be if it failed or was disconnected?
-
Re: The fusible link thread
It pretty much powers everything except the starter motor. Although if it blows, the starter still won't work because the trigger circuit is powered by the FL1.25B. When the FL1.25B blows, the van will become completely dead except the charge light will illuminate. If it's damaged or partially melted, then some things may still work and/or everything may blink on/off intermittently. It's a good idea to check it annually to be sure it's in good shape and that the connection points are corrosion free. Putting a dab of dielectric grease on it's terminals will help prevent corrosion and prolong it's life. Tim

Re: The fusible link thread
Ok, so mine broke off at the ring terminal. See photo below. However, the van still starts up normal and all electronics seem to work just fine (besides my christmas dash)
Does this mean the FL1.25B has been bypassed? I'd inspect further but I'm not quite sure what to look for. I'm a bit baffled that the van runs as normal with it completely disconnected :cnfsd:

I'd have to assume that too as it would be quite a trick to get those circuits powered up "wireless". Fuses, breakers and fusible links are not required.............unless something unexpected happens. If something shorts out, you could end up needing to replace the entire van rather than just a fusible link. Since vehicles burn so hot, it's not uncommon for them to take-out other vehicles and/or structures.
Of course that kind of result would be unlikely, but I'd recommend not tempting old Murphy. Tim

ill have to trace the wiring and see where it goes and if they've put another section of fusible link somewhere in its place. Don't know a ton about wiring. A wireless power system would be great :rol:

Re: The fusible link thread
Whenever I repair vehicles with "hacked" wiring, the 1st thing I do is inspect all accessible areas and look for hacks. Factory wiring is neat and clean. Hacks usually stick out like a sore thumb. Whenever a hack is detected, I remove all the "added" wires, then reconnect any cut or damaged factory wiring by observing the color codes. After bypasses and hacks are put back to original configuration I'll then test and troubleshoot to find, and then repair the original problem in a proper way.
In this case you already know the FL1.25B is the issue, so that should make the last part easy. I would assume the hack to be a larger gauge wire (probably 8 or 6 gauge) because anything smaller would likely not have been able to last this long. When looking for the hack, I'd start out checking the battery for an extra wire on the positive terminal. If there's one there, follow it to the other end and remove. If I had to guess, I'd suspect they ran a wire from the batt + to the + box next to the Air Flow meter (where the alternator output wire hooks into the system). Good luck. Tim

Re: The fusible link thread
I just went back and looked at your pics (earlier this thread) and see an extra wire at the + box (there should only be 2 wires here).
-
Re: The fusible link thread
Yeah, I'm at work at the moment, but if i remember correctly i traced that red wire back to the postiive terminal on the battery....ill have to double check (where the FL0.5G was missing - see photo from earlier in the thread) i assume that green section of wire spliced into that red wire from the + junction is a fusible link wire to replace the missing FL0.5G...?
anyway thanks for the info Tim, i think you hit the nail on the head. ill have to investigate further tonight so i can provide a better idea whats going on

Re: The fusible link thread
Ok, pulled out the battery and battery tray to get a better idea of whats going on. The two wrapped white/blue wires were running to the fusible link which was totally toast, the third white blue wire was running to the positive battery terminal, and the red wire (top of photo 2) was coming from the + junction next to the engine to the positive battery terminal. See attached photos. Hopefully I can fix this situation and it will also resolve my christmas dash :)
If anyone knows the wiring and can explain what the PO did here and what steps to fix it proper I'd be super grateful. Im a total noob when it comes to wiring/electrical.

Re: The fusible link thread
There's enough information here in this thread to help you through it. If you do not have the proper tools, terminals, and/or knowledge on how to use them, then it might be better to take it to a shop that does automotive electrical work. If you're determined enough to make the investment in tools/materials, then go to youtube and watch a few videos on crimping wires. In today's world you can get some darn good tools for pennies on the dollar--compared to what they sold for 20 years ago (I have some mechanical cable crimpers that cost me ~$300, but prefer to use the now available cheap hydraulic ones from China). Quality of the Chinese tools might not be the best, but they are still adequate to get the job done. If you use them right they do just as good of a job. For the bigger wires/cables, hydraulic crimpers do nice professional crimps. For the smaller wires Klein makes a nice set of crimpers that are affordabe. Here's some links:
https://www.amazon.com/PENSON-CAYQK0...+crimper&psc=1
https://www.amazon.com/Klein-Tools-I...=klein+crimper
https://www.youtube.com/watch?v=3LBZR_XiEnk
https://www.youtube.com/results?sear...tery+terminals
I like the video of the guy showing the Klein crimping because that's the way I do it (on the small wires). There's guys showing the proper way using the bigger hydraulic crimpers, but frankly the videos I watched were long, drawn out and hard to watch. This video (below) doesn't show the Chinese hydraulic unit, but it shows what a good crimp looks like, so it's good for reference. Tim

Re: The fusible link thread
One question, Do you have to upgrade this wire when upgrading alternator? I mean if you upgrade to a higher amperage alternator and change out the fusible link to a higher rating , in my case 250a anl fuse. Do I have to replace this wire with a proper size wire or wires? Or do I hit remove fusible link and connect the new fuse directly in place of the fusible link fuse?
-
Re: The fusible link thread
The wire/fuse you use should be based on alternator output (both positive and negative). Put the fuse the positive side near the battery. The new fuse and wire should be capable of sustained max output of alternator, but fuse should be rated slightly less than max continuous load rating on wire. Use this in addition to the existing fusible links, then just remove the the old alternator output wire that goes between plus box and big post of alternator (shown in the figure above).
Leave the old fusible links alone as they are still required to supply power to the van circuits. The fusible links are there to protect the van's wiring and are already sized appropriately. If you replace fusible links with anything rated higher than what the old wire can handle, you're asking for a melt-down (don't do it). If you're adding additional heavy loads to the system, wire them directly to the battery and use appropriately sized wire and fuses. If you want these loads ignition switched, use an appropriately sized continuous duty solenoid and use an ignition circuit to trigger the coil. Tim

Re: The fusible link thread
I've been going through lots of alternators, once or twice a year. Would this be a result of a bad fusible link?
-
Re: The fusible link thread
No. If I had to guess, I'd suspect you're using the cheap rebuilt alternators found at discount auto parts stores. Sounds like you need a real Denso alternator. Denso rebuilt units (acutally rebuilt by Denso) are much higher quality than your standard run-of-the-mill rebuilds. Here's a link to a thread with more information: http://www.toyotavantech.com/forum/s...lternator-woes

Re: The fusible link thread
Thanks, that was my thought too but I just had my alternator rebuilt 2 months ago by a highly regarded shop in Brooklyn. I'm taking it back to them in the next couple days to see what they say.
-
Re: The fusible link thread
They might not be aware of the special needs of our vans. Cheap parts may work fine in most vehicle configurations, but van alternators go through extreme service. Unless they're installing genuine Denso parts (in particular the diode block) I would not expect them to last. I was going through these things too until I switched to genuine Denso. The alternator In my daily driver has been doing great since I installed it in May 2014 (45k miles ago). Tim
