No power from chassis battery.
 

I have 2004 Holiday Rambler Admiral 30 PDD RV on a Ford chassis Went to storage yard today to take RV out to gas up for winter. Couldn't start RV. No power from battery. Checked voltage at battery OK. Suspect battery isolation switch may be faulty. Wondering if anybody knows if there is a fuse or relay that could be causing this problem. Was fine when taken to storage two weeks ago. Thanks. Phil Patman. Oakville

Grab a meter and start checking from battery to starter

No fuse on starter batteries.

If you checked battery voltage at the actual battery terminals, how about at the cable ends on the terminals, while holding the key to start.

That's the first connection a a common one to get corroded.

Thanks for replies. Going to start checking when rain stops. Reason I suspect shut off switch, no power even to entrance steps or lights. Not easy to get to. Thanks again. Phil Patman.

Phil-

The two places I've seen the chassis battery disconnect switch installed on our coaches is:

a) under the hood, and
b) inside the driver-side front storage compartment

The online manual for the 2004 Monaco Monarch (twin to the Admiral) does not say.

Thanks again to those who replied. Worked on RV yesterday and as suspected battery isolation switch was the problem. After removal (witch wasn't easy) I found the plastic piece with the contacts was loose. A piece of plastic had broken and fallen in preventing the copper contact strip from making contact. I am hoping to get new switch today. Thanks again. Phil Patman.
