No boats on fire....but several Fire Boats.....
Here is what I found on a B75K1.
Performed the measurements with a Stevens CD77 Analog Peak Voltage/DVA meter.
Voltage at spark coil measured at post with points and primer coil attached (everything attached to run the motor) Measured at the input post on the spark coil.....approx 125v
Voltage output of primer coil with points attached but not connected to the spark coil....approx 300v
Here is a good one.....when I measure the output of the primer coil only.......approx 15v- 20 v depending on how hard I pull.
Let the theories on that one begin!
I connected the negative lead to the grounding point of the spark coil for all the measurements. I also did the measurements with the negative lead connected to another screw on the engine block with the same results.
