Al Downs Posted August 9, 2013 Report Share Posted August 9, 2013 I am having some electrical problems. Some times when turning on the Master to lower the flaps for pre flight, there is not enough power to operate the flaps. Turning the Master switch off and then on again (sometimes more than once) fixes the problem. My thinking for this problem is maybe the Master switch needs to be replaced. Today a pilot had another problem. Below is the message he sent me regarding what happened. I started the airplane, following the checklist in this sequence: Battery on Choke, Throttle idle "Clear Prop" Start engine Set Generator on Set Avionics on When I set Avionics on, all of the instruments went dark. So I shut down following the shutdown sequence repeated the checklist. Same thing. As soon as I turned off Avionics, the instruments (EFIS) would come back on, if I turned the Avionics back on, they would go dark again. This problem seems different but may be connected. I went to the hangar to see what was happening and of course everything worked just fine. Took the plane out and put on .5 hours with no problems. Anyone have any ideas?
