I have a problem with and 01 Sportster ignition module. It quit and also blew a fuse and the breaker. I replaced the module. There is no spark at the coil, I installed a new coil and problem still persists. Any views? H-D serv. tech is also baffled.
Need a fresh train of thought. – Michael
Do you have 12 volts at the coil? Try running a jumper from the battery positive to the white wire on the coil, remove harness wire first. Sounds like you have a dead short in the main harness (blown fuse). Check all ignition wires carefully under the fuel tank and around the seat area. Has the fuel tank been removed for any reason? I have many ideas but start with these first. The jumper wire directly to the coil will eliminate the entire wiring harness; if the motorcycle does start you will only be able to shut it off by pulling the wire from the coil. Wrench Safe,
