RE: CH ignition
There is no dedicated left or right lead. If you get a spark when you turn it on but it will not spark when you rotate the crank more than likely the hall sensor is out. Do you have the sensor connected correctly, and is the battery in good condition?? You can also test by completing a circuit on the plug from the ignition unit, but I can't remember which two you use. E-mail CH or PM TKG here on RCU.
