I just returned Tuesday from a 2 week trip during which everything worked just fine. I parked in my driveway to unload with only the fridge running on propane and occasionally turning on lights. Today (2 days later) I went to move it to my parking pad and the chassis battery was completey dead. I had replaced it about a month ago. I know the coach batteries need replacing also and expected them to be low. However, they were all dead.

I believe there is a 'Battery Isolator' that should prevent the chassis battery from discharging when the coach batteries run down. Am I missing something?

Also, before I replaced the chassis battery, I had tried using the battery switch on the dash that is supposed to connect the coach batteries to the chassis for emergency starts. It did not work either.

Do I have a bad Isolator or do I just need to replace the coach batteries?

TIA.......Ron
