While out cruising the other afternoon a cursory glance down at the ammeter showed the system was fluctuating between charge, discharge and zeroing out. The gauge was all over the place. When I turned the headlights on the gauge stabilized to just above charging and when I turned them off the gauge would go back to fluctuating.
I found a pull over then proceeded top pound on the regulator which didn't effect the problem.
It even showed charging at idle which is highly unusual.

I beat-feet back to the barn, popped the hood, saw no wiring issue then shut it down. This is when I noticed the gauge still showed discharge. Pulled the regulator cover and determined the cutout relay wasn't cutting out. I could force the contacts open and they'd go back closed.
Sounding like the regulator right?

Well, I did find the issue. Anybody have a guess to what I found?
