So the starter fuse listed at 7.5A on my vans fuse cluster under the dash blows out anytime I put a 7.5 in as indicated and then the van wont start. However if I put in a 15A it starts up fine.
I recently changed the starter out with a refurbished Delco. Could this be the issue? Am I risking any further issues by using a larger fuse?

Thanks!
