It is a 1976 wheel Horse c120 automatic and it has the Kohler 12 horse power engine. Maybe I'm blinder I don't know how to read but I just can't seem to find it. I found one for a 74 but I'm not sure if it's the same. Any help that anyone can give me would be greatly appreciated. Again thanks everyone for all the help that you've been giving me every time I tinker with it and get something else working I have a big smile on my face. 74 and a 76 should be close enough to one another to use. Same body style. 1 Share this post Link to post Share on other sites
ebinmaine 67,334 #28 Posted April 13, 2023 Got that several years ago and been using it for half a dozen tractors or more. 1 1 Share this post Link to post Share on other sites

953 nut 55,125 #30 Posted April 14, 2023 Until you have it running and drive the "C" around you won't know what needs to be repaired while it is apart. Here is a bit bigger wiring diagram. 1 1 Share this post Link to post Share on other sites
oliver2-44 9,714 #31 Posted April 14, 2023 As you rewrite it clean each terminal, post or screw. If you have a Dremel those wire brushes for it are good for this. Retiring it now will give you a new harness to reinstall after reassembly. When you rewrite it if possible remove one wire at a time and replace it with a new one. When you done you can get some wire loom and zip ties to nested it up. When you install the new wires use silicone grease on the connections. Share this post Link to post Share on other sites
Frank DeHaven 27 #32 Posted April 18, 2023 Well after taking everybody's advice and I still can't thank you enough for all the information I have rewired the ignition. I ran out of colored wire so I had to substitute blue for green and yellow with a knot for white but I have everything written down as to what goes where. I also replaced the coil, the condenser, and the points. I know I have to replace the solenoid due to half thing to jump across terminals. But it turns over so hopefully with this new temporary wiring job it will run. Cross your fingers! 4 Share this post Link to post Share on other sites

But it did turn over! I can't tell you how happy that made me. Now I believe that it's going to need rewired it looks like a rat chewed on a lot of the wires and there's a lot of acorns in there. So now I'm just going to clean it up. Should I continue to rewire it and get a new solenoid or should I just start tearing it down so that I can clean it up and paint it? I'm just not sure if I should get the engine completely running and then restore the rest of it or if I should mess around with the wiring, which I would have to remove when I go to take the engine off, this restoration stuff may look easy but I'm just a newbie at it and I'm trying to learn as I go. Everyone on YouTube makes everything look so easy. Okay gentlemen and ladies have a good week perhaps I'll be on here with more questions Clean the tank, put new fuel line and clean the carb before starting and it will save you time later. Fix the wiring, change the fluids and then get it running to assess what else it needs. Make the tractor 100% mechanically sound first before restoring it. I have learned the hard way more than once on this!! Randy Oh, and welcome to Red Square!! You won't find nicer folk on the web anywhere!!!
