Cessna 1 #1 Posted July 15, 2018 The previous owner butchered the wiring on my 312-8. Is it easier to buy a new harness and start all over again. Now the tractor won't stop when the key is shut off. Share this post Link to post Share on other sites
953 nut 51,536 #2 Posted July 15, 2018 Is your ignition switch body grounded? Share this post Link to post Share on other sites
Cessna 1 #3 Posted July 15, 2018 I don't know. How do I check it? Share this post Link to post Share on other sites
953 nut 51,536 #4 Posted July 15, 2018 A down and dirty check would be to start the engine, turn the key off and then run a small jumper from a good ground (perhaps the Battery "-" terminal) to the switch body. If it stops the engine then the switch is not presently grounded. Share this post Link to post Share on other sites
