I am finding similar issues. My 99 Rex haul ford chassis would not seem to charge chassis battery but then it seemed to start. Were full timing now and I notice more than before. But just the other day the chassis battery went dead while plugged in. I charged it up and now I notice what I think is the battery parallel solenoid cycling on and off. It does not do it all the time. Is that how it charges the chassis battery by activating the battery solenoid?
