Good afternoon ,
I was just finishing up the last of the wiring and then ,, woops .
Appears the contact had been previously epoxied .
That would explain the stakon connector .

Il order a new magneto tower but I’m unsure of how to determine if the contactor is the correct height .
If not long enough then no voltage ,, but if too long I don’t want to damage the coil .

Can anyone provide some guidance on fit up ?

Thanks , Vince

I believe the contact pin is spring loaded so it does not require trimming or adjustment.

There should be a solder spot about the size of a dime at the top of the magneto coil. If the magneto coils are not broken somewhere on the magneto ring, that spot should be grounded through the coils to the opposite end of the coils. Take a ohm meter and test for ground on that solder plug inside the hogs had at the top of the coil ring. Then install the terminal at the top and test. If you test for a ground from the hogs head and the wire terminal on the contact, you should be just fine. Only way to be sure the magneto is working is to start up the engine and test the voltage at the top. If the magneto is working, and you are running on magneto, the voltage go up with the rpm of the engine.

Helps to check the length of that spring loaded reproduction mag contact, as it differs from Ford original coil spring contact.

Some solder pads on the field coil ring are tall, and the long point on the reproduction may be too long and need trimming . Check first that the mag contact base seats fully before forcing the part on the transmission cover.




In this case the spring loaded point was too long.
