My brother in law went last night to pick up a parts bike to get his 96 rolling (different story). The one we went to get is a 87 250 frame with aa newer 300 engine. Well the rear end would not swap over so we figured we would take a shot at getting this one running.
We found a wiring diagram for a 87 fourtrax, started at the battery and right off the bat found a blown fuse. Replaced the fused and popped again, long story short tracked it down to a grounded wire going into the ignition switch, fixed that and wow the motor turns over with the starter and sounds great!
After not starting we done the obvious and changed plugs, and made sure we were getting gas. No problem, check the coil for voltage during start and I get 0.0 DC and .5 AC so enough to say no fire to the coil. Thought the cdi was bad. (this is where I’m needing help) The cdi has an 8 pin top plug CDI. I found out the same as 98~00 trx 300. Well I’m having trouble finding the correct pin out wiring diagram for this one. Any help would be great. Will post pix in the next post.
