Today I ws working at the front of our trailer which required lifting and lowering the tongue with the power jack. During a lowering mode the jack power went off while I had my finger on the switch. The small lights on the jack would not work. I checked the in line fuse and the fuses near the battery but all were just fine. I put a meter on the service line to the jack but it was not hot. Of course that meant the emergency brakes were not working either. All other electrically operated systems, water pump, fans and lights in the coach are working. The coach was connected to 110 shore power at the time of the jack failure. I disconnected the 110 and everything that should work on 12 volts worked except the jack and emergency brakes. I think there is a time fuse on that line(car charge) which I will pull the panel on the belly tomorrow. Does anyone believe that there is another thing that I should check? Electricity has always baffled
me beyon simple circuitry. Thanks in advance.
