Default Re: Alternator troubleshooting voltage drain

Yes probably had a Delcotron with external voltage regulator. Always better to get rid of that, all it's nonsensical wiring and the VR..... and install a 10si as he did.
I believe he will be installing new harnesses.
The alternator wiring is very simple. He has it correct. I believe the problem is not in the alt wiring or the alternator. I'm guessing a bad battery, bad connection or bad ground, but need the answers and test to begin troubleshooting in an orderly fashion. All electrical begins with making sure the battery is OK and charged. Failing cells can be hard to catch.

All we really know is his battery is or was running down. I am going one step at a time and have my suspicions. He has now come to the right place. We will reset and delete all the confusion and testing he is doing.................someday.
