Have Classic Car Questions? Ask an Expert.
Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.I assume you are saying the added fuse for the charging system blows when you try to start the car, if that correct , what happens if you unplug the alternator and try starting and running the car. Dose the fuse then hold?
Can you tell me which fuse its blowing?
Dose it blow if you unplug the alternator? if so then you may have an internal shorting alternator.
