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 got ready to leave the MH wouldn't start - click click click. I now realize that the driver's dome light is likley on the engine battery not the converter or house batteries so assume it drained the engine battery. No worries, I will use the battery boost switch. Well, I held the boost switch in and it made zero difference - click click click. I tried several times with no luck. Thankfully we had towed our Jeep, had jumper cables and we were able to jump start the engine and get home.

I replaced the engine battery 2 yrs ago, the cells have sufficient water. Any ideas what my problem might be?
- Is the boost solenoid bad? How do I check it?
- Am I supposed to hold the battery boost switch for several minutes before I try to start?
- Is the power for the battery boost switch from the engine battery or the house batteries?
- other?

Any advice how to trouble shoot would be appreciated. If MH is not dependable my wife gets nervous that we will get stuck somewhere, me too for that matter!

Many thanks....
