I've read some RVs charge the coach batteries while driving, others don't.
This one does not charge the coach batteries. There is only one solenoid in the battery control box and most wiring diagrams I've found have 2. I don't know if it design that way or something is defective.
My emergency switch is also momentary, but easy enough to latch down.
So, you all think, the two batteries should be connected in parallel when the engine is running, separated when the engine is off (except for emergency starts)?
