Okay i know this is a dead horse but i am still a little confused by some of the posts on testing the ignition coil on a sportster? One post said to leave spark plugs in the cylinders for compression reasons and just put another spark plug in the wires to see if it produces a spark when turned over. This is my first step in determining why my bike won't start. And my other question is when i test the ignition coil primary and secondary with my ohm tester. What exactly is it testing if not hooked up to battery? Am i testing the magnetic part in the coil? Is this correct? Thanks for any clarification on this.
