1992 Trailboss 250 intermittent spark
My friend owns a 1992 Trailboss 250. It's been a great quad for years now. Unfortunately, it just recently started having problems producing a constant spark. Some days it will start fine, but then other days it won't start at all. When checking the spark, it either has a very weak spark, or none at all.
So far he's replaced a number of electrical items on it, including the CDI, all coils(including ignition), and the ignition switch. I told him that I would try to track down the problem for him, but figured I'd ask on here and see if anyone would have any ideas or suggestions as to what I should be looking for in regards to this problem. My first guess is a possible short somewhere in the wiring, but I won't know until I get a chance to look at it......
Any help would be greatly appreciated.
