Thank you John for your help in trying to get my Roketa 90cc (ATV21) up and running again.

Just to put the problem out there for anyone who may know the answer before John calls me back.......


I do not have any spark at all. I have replaced the battery with a brand new one and the engine cranks over easily and with the spark plug out, I do not see any spark across the gap grounding out.

Before I tear apart the wiring, I am checking all the componants and have come scross this.

Correct me if I am wrong here....the CDI has a 5 wire plug on it, I pulled it off and turned the ignition on and all 5 wires have 0 volts in them. As I crank her over, I find that the 2 wires from the magneto to the CDI become live with 0.12 volts. The wire from the CDI to the COIL also then carries the same 0.12 volts.

One of the 5 wires comes from the kill switch but does not have any power at all feeding the CDI box.

Sounds to me that maybe the magneto is bad, am I correct?

When I crank it over, what should the magneto be feeding the CDI box?

Thank you,

Steve
