Bert,
If you use a spark plug extender wire and hook your timing light to it, you will measure timing just fine. You just cant hook a timing light directly to the COPs wires as they are low voltage, triggering the ignitors.

plug one end onto the sparkplug and the other into the COP and clamp the timing light on the cable and .....let there be timing light




regards,

PS: No SAW signal with COPs, that is EDIS specific....Make a simple spark plug/cable extender and you will be able to verify timing with no problems.
