My 2 cents, get a jumper with at least 14 gauge wire and good alligator clips then find the "F" connector on the back of the alternator short the F to the big battery cable on the alternator and check your voltage output if its 14VDC or more your alternator is good and your problem is in the regulator or wiring if not your alternator has problems. This is just to check the alternator not a fix.
