In search of wheel horse 1 #1 Posted August 30, 2022 (edited) I’m searching for a replacement or a way to repair mine, the wire connection on the end of it broke off. Edited August 31, 2022 by In search of wheel horse Share this post Link to post Share on other sites
953 nut 55,324 #2 Posted August 30, 2022 The item you have pictured is not a starter generator, it is a trigger ignition coil. This thread will give a lot of information on the system in addition to alternative ignition systems if you should decide to go that route. 1 2 Share this post Link to post Share on other sites
squonk 41,158 #3 Posted August 31, 2022 Show us a picture of the broken off terminal. I had the same thing happen to me and I was able to dig around the area of the coil were the terminal is an expose enough metal to be able to latch another wire end on. It's already broke, you can't spoil a rotten egg. 4 Share this post Link to post Share on other sites

The black one that only shows the one end shows the flat male spade style wire connection that broke off (at least that’s what I believe that one is called). The black one I found the image of online but that one is no longer for sale. Share this post Link to post Share on other sites

squonk 41,158 #9 Posted August 31, 2022 Ok you can dig around that rubber/plastic and expose the remnants of the terminal. If I remember right, I used a dremel tool to cut away around the terminal piece then ground the metal square and used a smaller female spade terminal to fit on the coil. I did this on a GT-14 about 10 years ago 3 Share this post Link to post Share on other sites
Mike'sHorseBarn 2,998 #10 Posted August 31, 2022 I'd take a dremel with a little grinding wheel and very carefully remove some of that plastic around that broken terminal and see if you can expose enough metal to make it work. If not oh well, it doesn't work the way it is currently. 3 Share this post Link to post Share on other sites
oldlineman 1,481 #11 Posted August 31, 2022 maybe expose some so that a piece of wire can be soldered onto it. 1 Share this post Link to post Share on other sites

I don't think I would try to solder that but exposing enough to drill through to attach something threaded might provide a good connection point and hold up to the vibration better.

I don't think I would trust solder either. If I could expose enough to pop rivet or nut and bolt (2-56 hardware) I would follow with solder though. Or maybe a short wire pigtail soldered on with a male faston on the end. Maybe a blob of epoxy for extra measure.

peter lena 8,637 #15 Posted September 1, 2022 @In search of wheel horse what's stopping you from changing that coil location ,? if it were me , you can leave the old dead one there for looks , fake hook up , and get another coil in a better location , mounted on a , anti vibration pad , make the problem go away , repetitive problems give you a choice , you know what doesn't work , change it out , pete 1 Share this post Link to post Share on other sites

This coil was made for a short time and only used on a few different models. I just went and spent an hour in a junkyard looking for the part and unfortunately I didn’t even see one of the black canister coils let alone the one I need.

Even when you find on it's still a 50 year old coil. A lot of people convert these back to battery ignition when these go bad. Meaning installing points, changing the ignition switch, putting on a standard 12V coil etc. I have this same coil on an Electro 12 and when that coil inevitably does I already have the parts on the shelf to do a conversion. 1 Share this post Link to post Share on other sites

Here is a youtube video that shows you how to do it, it's not difficult. Keep in mind one thing he doesn't tell you in this video is that you can't use this kind of ignition switch without a solenoid which your tractor currently doesn't have. You can see where he put one in the video, but if I was gonna use one, I would hide it somewhere a little less obvious. 1 Share this post Link to post Share on other sites

Well... if worst comes to worst, I can offer to take a look and fix it if possible, but that would mean paying shipping here to NJ and back to MI with the possibility that it may in fact not be possible to fix. It's a gamble for you but if your willing to take the odds, I'm willing to try. Send me a PM if you are interested. In the meantime, can you get a clear, close photo of the broken terminal ? The ones you posted are all out of focus. Does your phone have a MACRO function for close photos? I may be able to tell more from that.

They pretty much break right where the terminal comes out of the coil body. You can even cut the plastic away with a hack saw blade if you don't have a dremel. and the use a file to shape what metal you expose so a regular terminal end would slip on. 1 Share this post Link to post Share on other sites
pfrederi 17,741 #24 Posted September 1, 2022 Before anything else conduct the two tests in the manual. No point in fixing the terminal if the unit is bad. You should be able to stick your multimeter probe in the broken end enough to make contact. 3 Share this post Link to post Share on other sites
23 Reo 229 #25 Posted September 10, 2022 Try to repair your original trigger ignition. They are unique and work well. My 68 Charger 12 is my best starting tractor and runs strong. Share this post Link to post Share on other sites
