Negative to trying a PT one. I thought I had pulled one off but I can't find it. I'll have to extract another. The bolt spacing is different though.
Regards readings, I put the negative on the end of the high tension spark plug lead and the positive on each of the electrodes for the kill switch/ timing.
This is based on a YouTube video on testing powertorque modules. They are meant to read in the 9.2 -11k olms range. Is the side pull FC different range to explain my much lower readings of around 6k olms with both my modules?

Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!
