Switches that look similar, but designed for lower current, are not appropriate. 1 1 Share this post Link to post Share on other sites

Same keyswitch, but it does NOT see the high current load as wired originally. NO issues going on 8 years... Share this post Link to post Share on other sites

squonk 38,814 #9 Posted May 14, 2023 Doub't it's the switch. Probably something going on with the starter gen. Share this post Link to post Share on other sites

Add a starter solenoid and lighter duty ignition switch along with smaller gauge wires to the switch. This takes the high amperage load off the switch and shifts it to the solenoid. An existing original switch's life could also be extended by adding a solenoid. 1 Share this post Link to post Share on other sites

So this is a simplified wiring diagram with the solenoid that someone posted on the forum: Assuming it’s the original K-181 engine which uses a coil and points as shown here, be sure there is no continuity between the ignition (I) terminal and the ignition switch body or any other terminal when the key is in the OFF position.

953 nut 51,398 #13 Posted May 15, 2023 Here is a much better drawing to work from. Uses a 103-990 ignition switch Share this post Link to post Share on other sites
