My alternator is pushing 45 volts which is far over the expected 14 volts. This suggests that my voltage regulator is shot. I’m trying to decide what to do... replace the voltage regulator? Or get a new alternator? I’m way over budget so I would rather not spend the extra money if I don’t have to, but I read that these alternators are built so that any internal sparks don’t reach the surrounding air so not to ignite fumes within the doghouse. With it being an old alternator I’m thinking “what if this thing is producing exposed sparks within?” What’s you guys’ opinion on this?
