JBuys 0 #1 Posted 6 hours ago I am trying to help an older gentleman from church to get his tractor going again. It is the breakerless ignition on a 12 Horse Kohler. Is there any electrical testing that I can do to see if the ignition system is ok? He pulled the motor and wiring from a running tractor but when it was installed into the other tractor, it wouldn't run. I am assuming it spins over but does not spark / fire. Let me know what to test and what the specs are. Thanks in advance. Share this post Link to post Share on other sites
pfrederi 20,985 #2 Posted 6 hours ago Very likely at some point in the removal reinstallation process they fried the Breakerless system by letting voltage get to the coil. You have to wire it like a magneto system. Before anything make sure the ignition switch is for a mag system ie. There is an M terminal on it Test to see if there is spark with a tester or just lying on the head. Kohler service manual covers breakerless Click on picture to download it. 1 Share this post Link to post Share on other sites

Not all Wheel Horses are wired alike so having the model number of the unit the engine is going into would be very helpful.
