You'll have to remove the coils from the car to test them.
Check resistance between the primary coils. It should be between 0.5 and 0.9 ohms. The secondaries should be between 5k and 8k.
Here'* the pinout for secondaries......on the top (plug wire terminals) read 1-4, 5-2, and 3-6. Easy?
This is what the techinfo states. I am confused. Wouldn't lower resistances be better. This states that the primary should be be 0.5 - 0.9 ohms where the MSD is 35 ohms. Also what about voltage.
And now that I am on the subject what is this for.
Jegs calls these MSD GM DIS Ignition Controls
I thought these coil packs just mounted right on without any mods.
Here is what I am looking at.
