Don't understand the question. Why am I using it. Using it because it works better with my motor setup. Has stronger spark, car has more power with it starts easier etc.. I have no spark from the coil wire to a ground when the coil wire is disconnected. Spark is supposed to jump to the ground when you tape that white wire to a ground. I don't have that. Was told from MSD that it's the points input circuit. I'm trying to figure if I have to send it in or if anyones fixed that problem themselves.Why are you using it?
Read instructions. Have no spark. And now know why. I'm just trying to find out if anyones fixed this point input circuit thing on their own.best read the instructions.
You do not ground the white wire. (As a test you can tap the wire to ground for a test)
