INSTALLATION INSTRUCTIONS THEORY OF OPERATION CAPACITIVE DISCHARGE The MSD Digital DIS Series Ignitions feature a capacitive discharge ignition design. The majority of stock ignitions are inductive ignitions. In an inductive ignition, the coil must store and step up the voltage to maximum strength in between each firing. At higher rpm, since there is less time to charge the coil to full capacity, the voltage falls short of reaching maximum energy which results in a loss of power or top end miss.

INSTALLATION INSTRUCTIONS 3 SPARK PLUGS AND WIRES Spark plug wires are very important to the operation of the DIS Series Ignition. A good quality, helically wound wire and proper routing are required to obtain the best performance from the ignition. MSD recommends using a helically wound suppression type wire such as the MSD 8mm Heli-Core or 8.5mm Super Conductor Spark Plug Wire. This type of wire provides a good path for the spark to follow while keeping Electro Magnetic Interference (EMI) to a minimum.

INSTALLATION INSTRUCTIONS WIRING GENERAL WIRING INFORMATION Wire Length: All of the wires of the MSD Ignition may be shortened as long as quality connectors are used or soldered in place. To lengthen the wires, use one size bigger gauge wire (12 gauge for the power leads and 16 gauge for all other wires) with proper connections. All connections must be soldered and sealed. Grounds: A poor ground connection can cause many frustrating problems.

INSTALLATION INSTRUCTIONS 5 WIRING NOTE: The factory rev limiter and all timing functions will still function as normal with the MSD Digital DIS-Ignition installed. Locate the ignition coils and identify which wire leading to the coil(s) has 12 volts on it with the ignition key in the On position. If available, refer to the vehicle's service manual wiring diagram to assist you in identifying the 12 volt wire(s).

INSTALLATION INSTRUCTIONS PROGRAMMABLE FEATURES The DIS Ignitions provide several programmable features that are set using the seven rotary dials on their end panel. The DIS Ignitions are programmed at the factory for operation on most 4, 6 or 8-cylinder engines with distributorless ignitions. Figure 5 Programming Rotary Switches. IGNITION MODE The first dial, Ignition Mode, has several features and must be set to configure the MSD to match your ignition system.

INSTALLATION INSTRUCTIONS 9 STEP RETARD A retard can be activated by supplying 12 volts to the Pink wire (Figure 6). This is ideal for nitrous applications or for a high speed retard. The amount of retard is set through the two rotary switches and the total amount of retard is 30°. When the Mode Switch is in positions 4-7, there will be a one second delay after 12 volts are removed from the Pink wire. In positions 0-3 the deactivation is instant. Figure 6 Wiring the Step Retard.

INSTALLATION INSTRUCTIONS Figure 14 MSD DIS-2 IGNITION WITH IGNITION ADAPTER, PN 8912 TROUBLESHOOTING Every MSD Digital DIS Ignition undergoes numerous quality control checks including a four hour burn-in test. If you experience a problem with your MSD, our research has shown that the majority of problems are due to improper installation or poor connections. The Troubleshooting section has several checks and tests you can perform to ensure proper installation and operation of the MSD.
PAGE 15
INSTALLATION INSTRUCTIONS 15 • Is the engine running lean? Inspect the spark plugs and complete fuel system. • Inspect all wiring connections for corrosion or damage. Remember to always use proper connections followed by soldering and seal the connections completely. If everything checks out, use the following procedure to test the ignition for spark.
