How to Troubleshoot MSD Ignition Products

MSD's ignition system produces multiple ignition sparks at each spark plug, rather than just a single spark with conventional ignition systems. This multiple spark technology greatly increases efficiency and power. If the MSD system does not seem to operate properly, a simple test can be used to determine whether the coil or the MDS product is at fault.

Instructions

    • 1

      Turn the vehicle's ignition switch to the "Off" position, then pull the coil wire off of the center of the distributor cap.

    • 2

      Disconnect the white-colored wire from the MDS ignition box, then turn the ignition switch to the "On" position, but do not turn the engine over.

    • 3

      Hold the end of the coil wire approximately 1/2 of an inch away from a metal surface, then tap the free end of the white colored wire against any ground point, such as a clean metal piece of the vehicle. A spark should visibly jump the gap between the coil wire and the ground point.

    • 4

      Replace the coil if a spark did not jump the gap between the coil wire and the ground surface, then repeat the test. If a spark jumps the gap with the replacement coil, the original coil was defective. If a spark does not jump the gap, the ignition box must be serviced by MSD.
