I have a project that involves using an Accel 140003 HEI Super Coil. The problem I'm having is that I don't know which terminal is the high voltage ground. This coil only has a 2 wire primary (red and yellow wires) with no blue/black as ground in other coils, so that is what's causing the confusion. Can anyone tell me where the high voltage ground is located?
Thanks, Bill
if you scroll down, if tells you to connect the yellow wire to the C slot which is the (-) and Red wire to the B+, which I think is the tach signal from the ignition.
I guess this means the (-) would be the common if you're not using it for automotive use.
The remaining wire is the HV lead..
This is obviously a auto transformer.. What this means is, the HV lead shares the same windings as your Red and Yellow ect, there is no isolation. the HV lead simply has a lot more turns after the B+ lead connects internally.
Hope that helped some.
