I got this van with low miles and it is in pretty good condition. I have been doing a ton of neglected maintenance. New front end, plugs wires, cap, rotor, master cylinder, brakes etc. I have something draining the battery over night. I thought the problem was the ignition, but since rebuilding that I am still having the problem. Does anyone know of any typical issues like this? Im thinking the regulator is probably fine since its a Toyota and I will be tracking down any grounds that might be the culprit but if anyone has advice, I'm all ears. Im ready to drive this thing regularly but not until I fix this drain.
