Just to add to the Power jack, I'll just call it service or preventive maintenance. But mine gave trouble shortly after we purchased the trailer 3 years ago, just when I needed it the most, but I suppose every time warrants that statement. So after purchasing a 12'' long Philips screwdriver in order to remove the top of the head/motor/cover, it was pretty easy to spot my issue. The aluminum push on blade connector had slipped off due to the wire being 1/4'' to short and also add a cheap aluminum connector. Replaced one of the #10 wire with better connectors and at the same time pinched all the other connectors closed tighter and have never had another issue since. Maybe this fall I'll remove it and completely dismantle it and grease with anti-ceeze the threads in the jack this time. good time to do it when the trailer is level and 30 feet from the shop door before snow decides to fall. Maybe one of your connectors slipped off and as soon as you touched the switch, the sparks will fly...
