Triggering My Msd

[redroc]

I just wondered if you have information on how many millivolts it takes to get the 6aL to trigger my coil.

I am not sure if I understand your question, but the small gauge MSD Red wire needs 12 volts in the cranking and run key position, and the MSD heavy gauge Red wire requires a constant 12 volts.
