Battery Master Switch
Has anyone ever had issues with the battery master switch circuit. When I throw the switch it does not kill the power. Switch seems to be working based on indicator light when it is in the on position with the key in the off position. Before I start hunting thru wiring schematics I figured I would ask. Getting ready to head to the east coast this week and although in the current state I have power, I would hate to have whatever is causing the issue to reverse the pattern and be without power while on the road.
Thanks

That’s common the switch on dash or by door connects to a relay, Is mounted in power compartment close to batteries should be 100 amps or more but it must be continuous duty that means it can be on all the time because they can get hot.

One for ceiling lights the other for tivoli lights on my Liberty. Available online or at NAPA etc.
12vdc, 100 amp or more, continuous duty

I traced it down to the battery disconnect relay in the battery compartment on my bus. In route to CT (currently in Ar for the night) and plan to take it apart after I arrive. Prevost part goes for about $390. They list a rebuilt part number as well but don’t sell that any more. It may be just stuck contacts as you pointed out.
Thanks

Like Don Said NapaAuto probably 30 bucks buy 2 just to have a spare, Turn off main battery disconnect then change it easy, And in a pinch jumper it
