here's the original thread I posted, about how we kept losing this circuit, it's the circuit the inverter supplies and bypasses...

We went on vacation last week, just camped at a local lake/campground. The circuit quit 2 or 3 times the first couple of days, then we had a 2-day stretch where it never faltered. Then it died while watching Law & Order, that was enough!
I decided to check everything closely. All wires were snug, all connections tight, everything appeared good to go. BUT, while grabbing (not just touching, more like 'yanking') the hot 12v input line, the inverter "thumped" and started humming-- the circuit returned.
For about 5 minutes, then died. I went back and yanked on the hot wire, and she thumped to life again. I figured I found the problem...
However, the cable bolt was plenty tight, so was the negative. No acid traces whatsoever. Maybe something loose inside?
I disconnected the 12v hot and covered the cable end with an empty milk carton to keep it from touching anything. I shut down the AC input. I removed the cover screws, and pulled the cover off...
Much to my surprise, other than a tad bit of dust, it looked absolutely brand new inside. All nuts and bolts on the inside were nice and tight. Nothing to indicate a reason why grabbing the hot input caused the AC circuit to re-ignite...?
So, I loosened every nut and bolt slightly, then gave every bolt and washer a turn, then re-tightened them. There was a small circuit board cable on top, I unplugged and re-plugged it. I pulled the 3 AC wires that were connected to a board via spade plugs, then reconnected them...
Then I put the cover back on, reconnected the 12v hot, turned on the AC, and hoped for the best...
The circuit didn't falter for the next 3 days straight. The rig is plugged in to house power now, since yesterday evening when we returned, the circuit is still alive. (FWIW, the clock on the microwave is how I know if the circuit quit and came back while I wasn't looking!)
I did nothing but "re-seat" all the electrical connections (that I could find). It seems that tight connections or not, every once in awhile they like a simple clean-up...
Hope this may be of some help to others!
