CH ignition
On a twin cylinder BME engine with ch ignition, is there a left and right sparkplug lead? And if so how do you tell which is which? Also, how do you toubleshoot for a spark? If I take out the sparkplug and turn the ignition on I get a spark. However rotating the prop I get no spark? Any suggestions?

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.

RE: CH ignition
The plug caps do not mater, Sounds like you have a bad sensor. If the ground wire is not connected when you let it fire it will kill the sensor

As Milton mentioned, you can fry a sensor if you have a rubber boot style set-up. If you have a shielded system and the plugs are in the caps it will not hurt.

The metal cap is grounded to the braided wire that goes to the unit. As long as you have a plug in it you will be fine. Well, UNLESS, you also have a ground strap because someone replaced the rubber boot cap with metal ones.
