Was getting ready to put the ST22BH into storage for the first time and had this happen.
After unhooking from the AC power I was showing someone the slide when all the power cut out half way into extending the unit. Then 30 seconds later it re-set and I could continue.
Same thing happened when I was using the power jack to unhook the truck. Half way through all the 12 volt power went out and came back in about 30 seconds.
There seems to be some sort of thermal overload protection in the 12volt system. I have not found info on it in the "manual".
Still having the problem.
This past weekend, if we had two or more lights on and the water pump kicked in it would trip an "overload" type delay. We would loose all power for 15 seconds or so and then it would come back on.
I checked the grounds, it cant be a breaker since it comes back on itself.
It will also do it if I run the power tongue jack for awhile.
Need to get this one figures out before the long trips of the summer.
Seems like it could be a ground wire that is loose. Some times the ground on the tongue is loose even tho there is a star washer holding it in place. I would re move this bolt wire brush the area and reinstall and see what happens
