Cool Coach elect power issue

Ok the other night I in my 1999 Rexall Airbus I was running off the coach batteries. I got up and walked from the sofa back to the bed room. As I stepped into the bedroom the lights all went out! I walked back to the front and they came back on...... I repeated this numerous times and the same thing every time!
Oh I should mention this also occurs when using the generator as well but when plugged into power it will not do it. I have cleaned all battery connections on my coach batteries and where it grounds to the chassis everything has a goodconnectio and the problem is still the same....

So now I'm just wondering if it could be a loose connect/ wire were my panel / inverter are located in hall way below closet right beside the bedroom door entrance. I will attach 2 pics one of the panel/inverter and the spot in the bedroom where I step and I loose power to the coach .

I'm going to pull it out next and check connections and just wondering if anyone has any other suggestions on what else I should be checking? Just want to mention that if I jump or stomp my foot in bedroom the lights/power come but as soon as I move they go out again
Any and all suggestions much appreciated

Welcome to irv2.
Can you lift the rug or floor where you step?
Or check your cabinet where the power panel is and put pressure on floor with someone else standing on spot and see if some wiring is coming loose in your load center most likely a ground which is common to everything.
You may just take load center cover off and check all wire connections on buss bar and main feed into the box.
The links below in my signature have other links for items in your coach, the Tech Info link is a good one for electric problems.
Enjoy the forums and safe travels.

Unhappy Coach elect power issue

Well no luck yet at tracking down my electrical gremlin! Took motorhome to garage and they did load test on coach batteries and they seem to ok. I found not only when I walk inside the power will go off but even just stepping on the step to go up into the motorhome and everything goes out. If I stand outside and push on the front corner of the motorhome the lights/power will go out! Push or jiggle it again and they come on.
Now this is only when running of coach battery power. When I'm plugged into 110v power at my house it works just fine....
All grounds to chassis are good all cables along frame are good. Connection in panel and inverter all tight and I grabbed and pulled vigorously on cables from panel in behind and where they run up closet wall and run along top edge of motorhome roof line. There are none of these running under the floor where I walk as was first thought, Everything is from panel and goes up top with the exception of the wires that run below floor for Hot water heater and theses I can visually see and gave them all a good pull as well and all were good.

Would it be possible that one of the 12v lights on the ceiling have a poor ground or loose connection on the power wire? Any and all suggestions much appreciated.
