There is a service bulletin that states the regulator must see a minimum of 4 volts to turn it on so to speak but can't find it at the moment. I believe a diode was added to the M wire to protect the ignition from stray current. They will not tolerate any voltage. Garry 1 Share this post Link to post Share on other sites

Garry Interesting the Kohler Service Manual indicates some applications had a diode in the Mag wire to avoid leakage... However in the 3 Chargers I have with either Breakerless or mag there is no diode... Maybe WH didn't spec them originally???? Share this post Link to post Share on other sites
SimonC 35 #103 Posted October 1, 2018 Ok, so I'll bypass the switch and see if the regulator comes alive. If yes, something is wrong with my switch. I could always put a dedicated switch for this as I'm guessing leaving the 12v on the regulator will drain the battery. Thanks Share this post Link to post Share on other sites
SimonC 35 #104 Posted October 1, 2018 any reason why this switch wouldn't work as a replacement if my current one is defective ? https://www.stens.com/430-070-ignition-switch priced very decently (15$) and is compatible with the Stens 430-223 wiring harness to make things cleaner thanks Share this post Link to post Share on other sites
