Re: Ignition coil voltage question
Okay then the turns ratio is approximately 18:1 so if you can check the high voltage output, you should get a fairly close estimate of the primary induced voltage. Or you use very high input resistance DDVM and check across the primary; Ground (coil metal core) to Kill terminal. Also you can check the specs on the D13003 transistor which has a BVceo minimum breakdown voltage of 400V and BVcbo of 700v minimum. Note: This is the main transistor in the Briggs newer coils, the rest are SMDs.
I have never needed to check the actually voltage. I just know the newer Briggs coils are using an SMD circuit board One side grounded all the time the kill terminal is floating except when grounded which shorts the primary winding so it doesn't produce any voltage.
