HeyMrP 83 #1 Posted May 2, 2020 Ok. I know my limits and patience levels! More patience levels than ability, but I LOATHE troubleshooting electrical. I have a 312-H project with an electrical issue. I can jump the solenoid and it will start and run just fine. Im sure that somewhere there is a bad ground or switch or wobbly doo-dad, but this is not the kind of work I like doing. I hate doing it probably more than I hate golfing (which I am very bad at). Anybody in the SE Michigan want to talk about a little paid work to fix this for me? Or possibly trade services? Or trade stuff for help? Im good at other stuff lol. Share this post Link to post Share on other sites
gwest_ca-(File Mod) 11,393 #2 Posted May 2, 2020 Do you know the model number of your 312-H? Iff not how about the spec number off the engine's ID decal and serial number? We may have some drawings to walk you through it. Each circuit has it's own diagram. See 3 tractor models 1990 31-12KE01 1991 51-12KE01 1992 51-12KE02 This one for 1990-91 This one for 1992 Garry 1 1 Share this post Link to post Share on other sites
HeyMrP 83 #3 Posted May 2, 2020 It’s a “Toro Wheel Horse Classic 312-Hydro.” Can’t find a plate with specific model number for the tractor. The plate on the Kohler Magnum 12 says “Model no. M12S” You’re tempting me to rewire this thing?! Get thee behind me you devil! Lol I guess I’ll look at the schematics... if I must. 1 1 Share this post Link to post Share on other sites
gwest_ca-(File Mod) 11,393 #4 Posted May 2, 2020 Will guess the tractor decal is under the left side of the seat on the rear fender pan. The start circuit is the one to follow. They show how the power gets from the ignition switch to the starter. You just follow the trail and make sure all the ducks are lined up. Working on adding color to them so they are easier to follow because not everyone will know what switch is where or what it is. Keep us posted on your progress.

Garry Boy do I feel dumb. been looking all over this thing for an ID plate. My multimeter had been sitting on it just right to cover it. 3112KE01 2 Share this post Link to post Share on other sites
