How does the C.H. Ignition system work?
The C.H. ignition is a small light weight C.D.I. (Capacitive Discharge Ignition). It gets it’s power from an onboard 4.8 V to 6 V 500MA or larger battery pack. It is triggered by a small magnet in the prop hub or a pulse wheel. This magnet triggers a Hall effect switch, which we call the pulse switch. Does the Ignition timing have to be set. Yes, just as it does on your car. It must have the spark at the right time. This is easily done and we give you complete instructions and even send you a degree wheel to make the job easier. Does the Ignition use a timing control to set the timing for starting and full throttle. Yes. For years we used the T.C.S.A. (Throttle Coupled Spark Advance). This works very well and several of the engine manufacturers still use this method for setting engine timing. This requires a linkage, usually through a Bellcrank, to move the timing plate to advance timing when the throttle is opened. In the past this has caused some minor problems by binding up or worn
