output voltage ???

Can somebody tell me what kind of voltage I should see coming out of my external ingniton coil?

Its a 79 motron medalist,, its 6v, and about 49 cc.

Whats a ballpark range,, enough to create a spark at the plug?

I'm getting 13 v at the spark plug cap when i crank it over,, but no spark at the plug when i put the plug in the cap and ground the threads of the plug on the engine head.

thanks in advance !!

13 volts isn't enough at all, it's more in the range of thousands of volts. In my experience it's usually the points that cause a weak voltage.

Re: output voltage ???

you will not be able to measure a voltage at the sparkplug with any conventional meter. It is a high voltage pulse. Check your point gap. Look for a spark when the plug is connected and grounded.
