HELP! Charging/Wiring Problem

OK. Will scrape away tonight! I'll be out of town for 6 days starting tomarrow evening. When I get back , I'll begin to explore the voltage drop problem. Thanks again to you and Nothingbutdarts for the help. :salute:

I would rather run a ground wire from the block to the regulator myself.

Just for kicks, ohm's check the alternator to the block and make sure it's OK.

You can do a quick check on the alternator by taking two jumper leads, put one on one field terminal to ground, start the car, have your volt meter connected to the alt. output stud, take the second jumper lead, hook one end to the other field terminal and touch it to a battery source such as the output stud or the battery. The alternator should put out full charge. Don't leave it that way for more than 30 seconds to a minute.
