It is grounded directly to the battery.

For an LS2 coil hook terminals A&B to a ground and +12V from the battery to terminals D. Then touch a 9V battery across C+ and ground. That ought to fire the coil.
Probably not a 100% test, the coils could go weak when hit at a high rate, but this will definitely find a dead bad one.

Surprisingly well. It was down on rpm and you could tell something wasn't right but I drove the snot out of it from may through October like that. Still did over 60 mph
