Thanks. Sorry about the slow responses. It says you replied 16 minutes but it just showed up now. Weird.

My bet is the battery feed and alternator output wires were switched. If so, maybe the person who rewired for the 70 up voltage regulator didn't keep track of the original layout. When he went to put the new alternator and battery feeds back into the bulkhead, he simply swapped the positions.

Let me look at your photos from the inside and see if I can understand what was done there.
If you can check the engine side and/or get a photo, we're looking to see what wires go in at P and J.
