Yes, I have full 12V to the coil. It drops to about 9V from coil to distrib.

I've tested the coil per these instructions I found on Stangnet:
to test the coil;

get an Ohm meter and

check primary resistance between Pos and Neg terminals on the coil
resistance should be 0.3 - 1.0 ohms

check secondary resistance between Pos term and coil wire terminal
resistance should be 8000 - 11500 ohms

repeat secondary resistance test between Neg terminal and coil wire terminal
resistance should be 8000 - 11500 ohms

check resistance to each terminal and gound(coil case)
resistance should be infinity

But my readings all come out less than these....e.g. secondary resistance on both pos & neg terminal are at 7000ohms or less and the primary resistance is at 0. There is a spark from the coil to the distributor but it's not a "fat blue spark" like some say it's supposed to be....
