Fuse to alternator keeps blowing


Asked by Feb 16, 2014 at 03:38 PM about the 1994 Ford Explorer 4 Dr XL 4WD SUV

Question type: Maintenance & Repair

I have had battery and alternator checked twice and they are ok.  The fuse to the
alternator keeps blowing, sometimes as soon as I try to put a new one in.  Any ideas on
what is causing this.  Of course, once it blows my battery amps go down.

Check for a bare wire going to ground. Also has any of the battery terminals been changed. If so double check that all the wires are hooked to the proper battery terminal.

There's a large plug on the alternator with (usually) 3 wires on it. Replace that. They're notorious for failure. You can buy that pigtail, as it's called, from your local auto parts store. HTH. -Jim
