Ok thanks a lot for all the tips & info. I probably wont have time to mess with it tonite, but hopefully thrusday night I can check the amp gauge. You guys are much appreciated



The QUICK answer is to run a heavy gauge wire--at least no10, better no8--from the alternator stud to wherever your battery cable comes "up" from the trunk, as, starter relay, solenoid, etc.


the proper term is called "voltage drop" and old Mopars are now notorious. Think in your head the "path" going from the alternator stud around through the harness, to the starter relay, through the bulkhead connector, to the ammeter, a factory splice in the harness, to the ign. switch (and it's connector) AND BACK OUT through the ammeter, through the bulkhead connector AGAIN, etc etc. There's a lot of room for drop, there.

For example, put a meter probe directly on the battery positive, and, while running, put the other probe on your ign. terminal, either on the regulator, or the feed to the ignition resistor.

It should be nearly ZERO. More than about .2, that's TWO TENTHS of a volt is too much.
