I have recently replaced the starter less than two months ago. Went to start the SUV and the 40 amp fuse blew in the run position. Looking for information on where to look for wires that could be short or the ground that may be loose.
Do you
have the same problem?

Ignition A fuse goes directily to ignition switch and starter relay with a red wire. May be a bad ignition switch or something connected to it.

I took the starter out and had it tested. Turns out starter was bad. Is there something that could be shorting the starter out? Do not want to keep replacing the starter. I am on my third starter.

A lot of this depends on the supplier of the starter. Cheaper ones can have a lot of problems. As long as wires are not burnt/shorted out it could have been a bad solenoid shorting, hard to say with out checking it.
