RedRider 120 #1 Posted August 5, 2014 When I purchased my 500 Special it had an 8 hp Kohler with wiring that was all chewed up. Now that I am restoring it I have located a correct recoil start Tecumseh H60 that will be going back on the tractor. I have been unable to locate an ingnition switch wiring diagram for a recoil start H60. I figure that it is probably something simple that involves creating or breaking a ground to the engine through the switch, but I need to know where the wiring should go to the engine. If anyone has a diagram to share, or better yet pictures of an original setup, I would greatly appreciate it. Share this post Link to post Share on other sites
wallfish 17,549 #2 Posted August 5, 2014 There should be just one wire coming from the engine. The switch will ground that wire to shut down the engine. If there is no wire coming from behind the flywheel then you will need to connect one. The tractor manual will not cover that but the engine manual should. Click on the "Manuals" tab (upper left) and then type "H60" in the "search" to find the manual you need. Share this post Link to post Share on other sites
RedRider 120 #3 Posted August 5, 2014 (edited) Thanks wallfish for your response. I did check the H60 manuals, but again I only saw diagrams for the electric start models. The H60 I have did not have any extra wiring coming from behind the flywheel, I believe it had a tab mounted on top of the engine to create a ground at the top of the spark plug. My original ignition switch is pretty rough, is there any suggested aftermarket replacement for this? Edited August 5, 2014 by RedRider Share this post Link to post Share on other sites

My original ignition switch is pretty rough, is there any suggested aftermarket replacement for this? The least expensive switch is likely part # 103991 or an after-market equivalent just because it is so popular. Just use the M terminal for the ignition wire and G terminal for ground.

wallfish 17,549 #6 Posted August 7, 2014 You'll need to remove the flywheel and run a wire to ground the points with a switch. The points are under the little aluminum cover that's held down with a spring steel wire. You should see an insulated bolt coming out the side of the "can" the points are in and you should run your wire to that. When grounded by the switch, it will shut down the ignition. There will be holes on the plate you can route the wire through and out to your switch. You will probably see the broken or cut wire when you remove the flywheel. You shouldn't ground the spark plug with a switch since the spark will probably jump the contacts inside it and cause no spark all the time. OR, you can just take the easy way out and choke the carb to shut the engine down. Electric or pull start makes no difference since the only main difference between them is the starter, charging coils and rectifier. Both types use the same wire to ground the points to shut down the engine. Share this post Link to post Share on other sites
RedRider 120 #7 Posted August 8, 2014 Wallfish, that makes sense now. I had the flywheel off when I rebuilt the engine and I know what you are referring too, I just can't specifically remember seeing an insulated bolt. I will pull the flywheel off when I get some time and check again. As for the engine grounding through the spark plug, that's the way it was when I got the engine. I don't think the engine was off of a Wheel Horse originally, possibly a go-cart or something else. I had a junk H60 from a 657 Wheel Horse that I robbed all of the external covers and brackets from to transplant on the newer rebuilt engine, but I don't plan on keeping the grounding tab on top since it isn't original for the Wheel Horse configuration.

wallfish 17,549 #8 Posted August 9, 2014 Here's a pic of one which has the charging coils for electric start but I believe yours should be similar. The arrow indicates the insulated bolt to the points you can use to connect a wire. Share this post Link to post Share on other sites
