ok i measured where the plug in goes into the spark plug cap and its reading 4.5v, but im trying to measure the ohm value of the coil which i think is part of the spark plug cap but i cant get a reading. i had put a new plug in it so i know the plug is good. so anything else im missing?? thanks!
The coil is the small cylindrical part mounted on the frame that the spark plug wire goes too. Spark plug wire comes out of the bottom, and should have wires coming out of the top. (about 3/4" dia x 1" long, not very big)

You will ahve to disconnect the wires coming out of the top of the coil to get a good ohm reading.. especially if something is grounding it out like the kill switch. As long as it's not an open circuit it "should" be ok.

#4 below is your coil.
