skrusins 128 #1 Posted September 1, 2014 Hi, I'm sort of vague on this setup. A freind of mine got a hand me down for a uncle who past away. The WH will crank but no spark. The test button on dash will not light the idiot panel, I feel some of switches have been bypast. Can that panel prevent the motor from spark? I check the fuses they all have 12V. Can I jump start it by putting a jumper wire between + coil and start on ing switch? Looking for more ideas to look at he does live 20 mi away. Share this post Link to post Share on other sites
WH nut 553 #2 Posted September 1, 2014 The coil should have 12v to the positive side with the key on. If not you can apply 12v to see if she will fire. Share this post Link to post Share on other sites
skrusins 128 #3 Posted September 1, 2014 Thanks for the help. I'll drive out there and give that a try. I really appreciate your help. Share this post Link to post Share on other sites
skrusins 128 #4 Posted September 2, 2014 WH nut, I tried as you suggested with the key on there is 12v going to the coil. I hoping there is something else I could try.I've been searching in RS without any luck.I read that a jumper wire from bat to + side of coil eliminates safety switches that didn't work. I wish I knew how to bypass that board to see if that fire it up. I test the board with my 414h Kohler an that worked. Share this post Link to post Share on other sites
km3h 543 #5 Posted September 2, 2014 (edited) Check the blue wire at the solenoid for 12 volts when you turn the key to start. I like to use a test light so I can see how bright the light is. This gives me an idea as to how much amperage I have there. If there is no voltage or the light is dim, you probably have a corroded 30 amp fuse in the fuse block or in the case of no voltage, it has blown. If you have this fuse block it is below the battery box and has three fuses in it. It is notorious for becoming dirty and causing problems.

WH nut 553 #6 Posted September 2, 2014 If you applied 12v to the + side of the coil you have eliminated everything but the ignition on the motor. If still no spark you have either a bad coil or module 1 Share this post Link to post Share on other sites
Martin 2,130 #7 Posted September 2, 2014 (edited) The board with the warning lights is just an info part, it does nothing to hinder the rest of the electrical... you can disconnect it altogether if you want, it has no bearing on whether the rest of the electrical on the tractor works. If you have no spark with 12 volts to the coil, it's most probably the coil or module. If you don't have access to a manual, I could post up here the sections for testing those two parts, but it might be a few hours before I can do it.
