207WF Posted October 18, 2022 Report Share Posted October 18, 2022 Last time I turned it off, the engine kept running. I switched back and forth from position 1 and 2 to off a couple of times and then it went off. Visual inspection showed no loose wires on the switch. I wonder if it could be a bad ground at the other end, or what? WF Quote Link to comment Share on other sites More sharing options...
Anticept Posted October 19, 2022 Report Share Posted October 19, 2022 Assuming carb aircraft: check resistance at the wire 6 pack from p lead to ground pin within the same pack at the ignition modules in each position to begin diag. Quote Link to comment Share on other sites More sharing options...
Ken Posted October 19, 2022 Report Share Posted October 19, 2022 I had this issue once. It ended up being a loose ground wire on the ignition switch. 10 minute fix. Start simple first. This seems to be a common issue. In Quote Link to comment Share on other sites More sharing options...
Roger Lee Posted October 19, 2022 Report Share Posted October 19, 2022 The engine grounds out to shut down. It's either the wires on the back of the switch, the grounds at the 6 pin connector at the ignition modules or those two wires coming into the instrument panel have been cut or pull off the bus bar in the panel.

207WF Posted October 23, 2022 Author Report Share Posted October 23, 2022 Thanks for the advice, guys! I cleaned all the grounds related to ignition, even found two from the ignition modules to the intake manifold that I had ben unaware of. The subsequent shut down was much more crisp.
