Bolens Diablo 503 Wiring and Electrical — Bolens Hus Ski and ...

Hi Bruce: To all that have a 503 beware. My ignition switch shorted out sending 12 volts down into the points starting a small wiring fire. After my frustration level came down I began to research the problem. Inside the key switch the brass disc had fallen to one side and this was the cause. The solution was a new ignition switch (that is not available anywhere around me). I also had to replace the coil and stator. I got a switch for a cub cadet tractor but had to put in a toggle switch as well. The ignition switch now turns on my lights and cranks the engine and the toggle switch turn on the ignition. My 503 is now running perfect

Thanks Steve for sharing and educating us. It’s a good example of how one can share after an experience and the explanation of the failure helps us all. The good new is new switches are available. In addition, plugs that match the backside of the key switches are also available. The importance of the plug is to protect the ‘hot” positive connections on the back of the switch when you are swinging a wrench in the tight area trying to remove the spark plug. Sparks here above the gas tank are not good and can cause damage as Steve described above.
