Good afternoon, my name's Tom Brintzenhofe. Certified master mechanic out of Reading, PA and today I'm going to talk a little bit about how to troubleshoot an electronic ignition system. Troubleshooting electronic ignition systems is a little difficult for your average do it yourselfer. These systems have become so intricate and complicated over the last couple of years that just your average tools alone, you're just not going to be able to do it. And now back in the 80's, early 90's, diagnosing these systems was fairly easy. All you needed was a test light and a multi-meter and you can get it done that way. These new systems you need a thousand dollar piece of diagnostic equipment. And very detailed instructions on how to diagnose them because if you end up getting in there with a test light or a multi-meter and touching the wrong terminals you end up frying the computers and what not. The easiest thing I can tell you with diagnosing an electronic ignition system is 1. you need to find out basically, as long as your maintenance issues are taken care of, your spark plugs your wires. A lot of newer systems don't have caps and rotors so you get away from that but if your regular maintenance is taken care of the best thing I can recommend to you is take it to your local garage and have them take a look at it. Scan it, make sure there's no codes or anything in it. Outside of that, that's your best bet. Trying to do this in your back yard is going to be very difficult and you're going to end up replacing parts that's going to cost you a lot more money than it would have needed if you had just taken it to a garage and have them take a look at it for you. And that's how you diagnose an electronic ignition system.
