Milt, I've seen bad hall effect sensors test fine with an ohm meter, but not run the car.

The resistor of some sort, should be a capacitor, or some times called a condensor. Never seen one cause a problem on a HEI .

I can't find an old one around to test, but I "think" the red is hot to the low voltage side, yellow is the ground to the low voltage side, black is the ground to the high voltage side, and the button on the bottom is the positive for the high voltage side.
