Hello, My Rodeo, keeps blowing the ignition coil fuse inside by the driver. How can you tell if/where a short in an ignition coil is? There has to be a reason for the fuse to keep blowing. Once the fuse blows, the starter will turn over fine, but there is no ignition. Sometimes it won't turn over and will just click, like alternator problems, but we can't find any problems with it. As soon as you replace fuse it turns over and starts.

You have to follow the wire to that fuse or look on engine/frame etc anywhere where harness can make contact. You might try a compass if it goes silly that may be where the short is. But mostly it's just experience. It may be drawing to much power as well causing the fuse to blow it's something that a pro shold really look at.
