I have this four wheeler and it has no spark.
It has no battery. I'm fine with using just the pull start and no lights or anything electrical (that isn't mandatory for spark/running the engine)
Bought a new coil. Also got a spare black CDI box, neither got the bike to have spark. Also tried new plug.
I took the rectifier out to replace with the spare parts I bought from a 1988 model....turns out the previous owner used wiring and the rectifier from a Honda TRX300 quad.
Any ideas? Or would I be best to buy a completely new wiring harness and go from there?
