Battery Boost Not Working
We have a Winn 2007 Voyage. We camped recently plugged in at a state park. My DW used the driver's seat to do her cross-stitching and used the driver's dome light over her shoulder. Well when we go...

Don't know the wiring of your coach, but it is possible that voltage to activate the boost switch comes from the chassis battery. If so, and the chassis battery is dead, there may not be enough voltage to close the boost relay.
If this is the case, use a jumper wire (small gauge is fine-- you will be powering less than one amp) from the house battery terminal of the boost solenoid to the positive signal terminal (will be a small wire/terminal).
Once both banks up, you can check the solenoid, and it should be working (again, if my speculation above is correct). If you need advice on how to verify it, let us know.
Long term, you need to make arrangements for the chassis battery bank to be charged (assuming this was not OE).
