2006 Popular Battery Switch Only Works With Generator

[Junglejaney]

Hi. I replaced new 2 new agm batteries in Rt. The switch won't turn on or off. I turned on the motor the switch won't turn on or off. I am able to turn on the generator and after a minute or so the triplight turns on and Im able turn on the switch.

I ordered a new intelletic RV battery switch/relay (it should be in today), I did check the 5 amp fuses, they are good on the old one. But since it works with the generator, I'm thinking that is not the problem.

Could it be one of the 50 amp fuses next to switch? If so what are they?
How do you test it with a voltmeter?

Thanks. Jane

Sorry I can't help, I'd thought I'd chime in hopes that others might provide help.

The generator running the coach 110v powered charger is going to be at a higher voltage than the batteries, which might be a clue that you have a loose wire or cable at the the batteries or the Intellitec is getting weak. I think it is unlikely that the breakers would be tripped as the charger and batteries are connected to each other before those item unless they have been altered.
