What is this switch?

I did the test like you said. still no fire it turns over great but didn't start. I ran the wires like you said pos battery to pos on the module and pos to the pos coil all at the same time. No change.

Was the distributor chked for an 008 gap at the reluctor?
Absolutely postive the module is grounded through it's metal contacts on it's frame where the screws go though it?

With the ground wire off the distributor, are you getting power out the negative side of the coil?
)Power the coil and test light the ground terminal on the coil)

All this chks out and I would have to say the module got burned out by reverse polarity possibly.
