What did I miss?
Charge/jump start relay, should not keep alternator from powering vehicle, standard dash gauge is for vehicle battery
Sounds like dirty connections for battery cable and stater cable etc.. At the relay
My dash ammeter has never worked. I have plugged a voltmeter/USB receptacle device into my cigarette lighter. This tells me chassis system voltage and it beeps if it drops below 12 volts.
It is similar to this one:

The vehicle is a 1990 Winnebago Warrior built on an E350 chassis. It has a 100 amp alternator.
First, we swapped out the external voltage regulator. This had no effect. I then replaced the alternator. This also had no effect. I tried the momentary on switch to gang the house batteries to the engine battery (boost mode), and this had no effect on registered chassis voltage, which made me suspect the solenoid.
I went and gave the solenoid a whack, and then my chassis voltage jumped back up to 14 volts. I assumed that the solenoid was somehow in the charging circuit.
I don't understand how the electronics of the house/chassis charge/off/boost switch work.
