My daughter has a 1988 LT80. About a week ago I started it for her and it was flooded. It ran rough for about a minute or so and went dead. After it died, it had no spark at all. I've tried a new plug, swapped a coil from an LTF250 (for test purposes), etc... and no spark.

Does anyone have a wiring diagram and electrical specs they could email so I could trace this problem?

 

soory but no diagrams here . have a 87 for my son same type of prob, checked coil too. since i had no diagrams myself i sent it to a local shop had them test it. they told me the stater was bad . cost me $40. for the test. bought one on ebay for $30 (used). installed and has been great for a year now! not sure if this is any help but it cant hurt to try. good luck also just make sure your ground wires are attached good. one under the seat near the coil,another on the motor above the brake petal

 

Thanks for the help. It turned out to be the coil/CDI unit (they are made together on this model and maybe all others too...). Running great now!
