No excitement!

My exciter wire is once again not providing excitement to the battery relay, so the solar panel isn’t maintaining the starting battery and alternator isn’t topping off the accessory batteries. Relay is fine, just tested it with allegator clips. Bad butt connector somewhere, nothing obvious. I’ll have to get out the test meter and work backwards to the cab where I know I have power.

I thought I had mastered automobile electrical wiring, haven’t had issues in a few years. But vibration, dirt and salt is tough mothers.
