hey guys went to go out the other night and fire the sled up and its running on two cylinders. 1 and 2 are firing but three is not. I tried replacing the plug and nothing. boot was replaced 4 years ago, and the other 2 have a nice bright spark wondering if it could be the wire? 1 and 3 are on the same coil so i would think the coil would be OK since the spark is so strong on 1. any suggestions on where to start i haven't tried ohming the wire can you just unthread them from the coil? thanks in advance guys!
