The magnetic pickup (inductor) that is found on most timing lights is made to operate with the magnetic fields present in a wire that has 10000 volts or higher running in it. A rather high field strength compared to a 12 to 14 volt wire. IOW, it goes between the coil and the plug. With COP's, there is no high energy wire exposed, only a low energy wire, and this wire does not produce enough field strength (Gauss) to trigger the strobe.

They do make testors, if you wish to pay the cash. Here is an example on the following link:

Thanks for the replys & links . I'm going to find a "shade Tree " way To do this .
My X is 1500 mi. away, so I can't go out & play with it right now.Maybe because I can't go out & look @ the situation I don't see the complications.
Why can't a lead from the cop be hitched to a spare grounded plug ,the eng. started & the spark on the spare plug or the lack of it observed ?

It might work. It sure will with any old time engine. I don't know if it could damage the COP, though. The computer wil probably have a fit while you are checking it this way.
A scan tool will report a misfire in a cylinder. That is how we usually figure this one out.

I go way out in the Utah Mts & want to be able to fix the X so I can get back home in a breakdown. I could buy a tow truck for what it costs to get towed out. I carry emergency tools & the spares to do it. Bring home the Biggest pieces Dad always said .

you would have to have lots of cops all die at the same time in order to not bring it out. mine is back to running on 9 again, i just have to hook the puter back up to it to find out what one is missing now.

I don't know how much power 9 cyl. produce @ 10,000 - 11,000' MSL . I'm glad to hear you can limp home on 9 , if it's flat or downhill. But that's why I carry spare's , Factory Manuals ,ect. Usually my spares are used to get some other poor soul lost in the wilderness back to civilization .

to be honest unless you knew you were on 9 or even 8 at times you wouldn't really know it. i can feel when i have a miss but it just has a few little stutter spots in the rpm range and my fuel mileage goes down about 2mpgs
