Thank you for your reply. I really don't mean to be evasive or not answer questions...and perhaps what I wrote didn't line up with what I was trying to convey. I ask my son to look at and try different things that were suggested. I guess that when I say all or nothing that was self explanatory...my apologies for the confusion there.
I meant about the selling of the moho was of course after we got it fixed...again, any confusion there was my fault for perhaps not stating that correctly.
Since I was not there, I don't know what to say except for my son and wife have conveyed to me..."when I plugged into shore power nothing worked; however, upon fiddling with the salesman switch mom said what are you doing, things are working." My son stated he kept an eye on the panel for the batteries and said that the power was coming from the shore power. The charge level did not go down over night nor did the generator run. So my only conclusion, unless someone has another logical explanation, is that the switch or solenoid must have something to do with shore (AC) power. When they returned to the storage lot and turned things on they did not work until he flipped the switch a couple times (on DC power). Again, I am only posting what I was told.
As for the solenoid in my photo being the one on the right...I'm sorry, but Being not familiar with what it might look like and only going on photos another (actually not sure who) posted what I see on the right looks nothing like what they posted. It actually looks like memory boards for a computer on steroids (three light gray bars just under the light). Or, is it the black box with clear cover on it just above the strip that has wires attached to it on the bottom right (sorry, mind is drawing a blank on its name). The only other object I was thinking it might be is a small canister-looking piece (close-up in 4th photo from the top) in the upper left of the compartment. For which ever it is it looks like something we can do we just need fairly detailed directions (some photos would be great...but not pushing it).
I think/hope I covered most, if not all, the items. One last question would be is the inverter should be on all the time? Where might it be located? I thought when we purchased the moho the guy pointed it out as having access to it in the main pass-through cargo bay; however, my son doesn't see it (IF he really looked really well...lol).
Thank you so much!
