Would be good to isolate your MSD wiring layout from the factory wiring.

Like use a Relay to power full 12 volts "from the battery" (with fuse) triggered by factory switched ignition wire.


Want to check the Alternator output volts and battery voltage with the engine running when you are done.

Hopefully it's 13.5 -14.5 when you check. Too low or too high is not good.

Isolate it how, it requires both ignition switched wires, and the blue white trace feeds to voltage regulator
