• The only wires connected to the coil terminals are the MSD Orange to coil positive and Black to
coil negative.
• The small Red wire of the MSD is connected to a switched 12 volt source.
• The MSD power leads are connected directly to the battery positive and negative terminals.
• The battery is connected and fully charged if not using an alternator.
• The engine is equipped with at least one ground strap to the chassis.
• If running a 4 or 6-cylinder, the cylinder count must be modified in the Pro-Data+ Software. Default

LED
The LED on the side of the MSD monitors several operating conditions of the MSD. If the LED indicates
that there is a problem with the ignition system, follow the steps through the Troubleshooting section.
The LED will appear to be on steady at above idle speeds when everything is functioning properly.
• When 12 volts are applied to the small Red wire, the LED will turn on to indicate power.
• When cranking or running, the LED will blink for each trigger signal.
• Code 2 will flash for low battery voltage.
• Code 3 will flash for high battery voltage.
• Code 4 will flash for converter off (ignition problem).
WARNING: The MSD 6-Series Ignitions are capacitive discharge ignitions. High voltage is present
at the coil primary terminals. Do not touch the coil or connect test equipment to the
terminals.
