Skwerl58 705 #2 Posted October 19, 2023 If it has the original switch it should have a connector that will let you unplug and plug all up at once. I am a beginner but the second schematic has you covered with wire color and location. Someone with more knowledge should be along shortly with a switch number and info. Enjoy your tractor! 1 Share this post Link to post Share on other sites

(The engine has an automotive style ignition coil.) The lower diagram is for a magneto ignition. (the ignition coil runs off from the flywheel.) This should be the correct diagram for you tractor, unless the engine has been changed. You will require a switch for a magneto coil, It must have an M and a G terminal on it. Your new switch will have letters stamped on to the terminals B-battery, G-ground, S-start, M-magneto, etc. If you are not buying a direct replacement, you may have to move the wires in your existing plug to match up with the new switch.

953 nut 55,394 #6 Posted October 19, 2023 Here is a bit of information that should help. You can get a new lawn mower solenoid at Home depot or lowe's as well as ant auto parts store. 1 Share this post Link to post Share on other sites
