I can't get my Fiesta to stop charging at 15v. I've replaced the alternator & battery but I'm still getting 15v. Any ideas? No error codes so far but I'm only driving it a few minutes at a time to get datalogs. I don't want to cook the electrical system running it at 15v for too long.
Backstory: I'm pretty sure this happened when I was replacing my a/c compressor. When I was reinstalling one of the hoses, the metal hose shorted out on the alternator which blew my main 200a fuse (integrated into the positive battery terminal). I replaced the main fuse and I'm pretty sure that's when it started charging at 15v.
