96 gtx STUMPED

[Wessler]

have a 96 gtx. The ski runs great. Last weekend the ski started misfiring at 3k rpms and above. I thought got to be rectifier. Disconnected red rectifier wire and misfire went away . Ordered new rectifier and installed. Misfire came back. I’ve replaced rectifier 3 times in the 15 years I’ve had the ski and always fixes theissue. The WEIRD thing this time is that the high temp led is constantly flickering. No matter if the rectifier is plugged in or not. Unplug temp sensor and still flickers. New ground wire to starter installed and same issue. Any thoughts?

I think you should check the small ground wire from the battery to the rear electrical box. I have found the faston connectors corrodes where the wire is crimped and also the bolt/post that the small black wire connects to in the rear electical box corrodes and should be cleaned up or replaced as well as all the other ground connections that are on the bolt/post. If your temp light still flickers after that then trace the tan wire on a schematic. It goes to a lot other other places (MPEM,beeper, tach, info guage) where the connections and wires should be checked.
