12v DC system failing sporadically
I have a 1997 Tioga Montara (Ford E350 V10 engine). Nice rig, works well. I disconnected from shore power 110v, and suddenly the 12v DC battery systems would not work. Lights, fan, water pump, etc...

What you NEED IS......
A multimeter so you can test the voltage at various points to narrow down the problem.
Guessing and throwing parts at a problem like this often turns out BAD....meaning time consuming and expensive.
Most likely causes:
Loose or corroded main battery cable connection.....including the main battery disconnect switch/solenoid.
Intermittent open connection INSIDE one of the "newish" batteries.
