Hi All. I have a Craftsman riding mower model 917271121. It has a 16.5 Kohler CV16s - 43513. Currently I have no spark. I have ohmed out the coil , if I recall it had 4.5 ohms. I did make the mistake of trying to use sandpaper to clean the rust off the ends, and also clean the rust off the magnets on the flywheel. The spark seemed weak before I cleaned it. I thought if I cleaned them off it would be stronger. It appears I have done more bad than good. I also read somewhere that you can test the ignition coil and relays this way (copied and pasted) below.
"If you have not fire to the spark plug, either the ignition module is bad, or the operator presence relay number 1 is bad.
The best way to test is to remove the blower housing from the engine. Disconnect the wire (either white or black) that plugs on the ignition module. This is the kill wire that grounds out the module when you turn the ignition key off. If the engine has no fire with the kill wire disconnected, the ignition module is bad. If you have fire with the kill wire disconnected, either the seat switch or the number 1 operator presence relay is bad. "
On this ignition coil there are two wires, a black wire and a yellow wire. The above test only mentions one wire, not two. I was not sure if both wires need to be removed or not. Any help will be greatly appreciated. Thanks.
