1. Black Heavy Battery BYPASS CONNECTOR To GROUND IGNITION ADAPTER 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 If you have any questions concerning your MSD call our Customer Service Department at 915 855 7123 Monday Friday 7am to 6pm mountain time MISSES AND INTERMITTENT PROBLEMS Generally a miss or hesitation at higher rpm is usually not caused by the ignition Most probable causes include a coil or plug wire failure arcing from the plug boot to ground Several areas to inspect are e Always inspect the plug wires at the coil and at the plug for a tight connection and visually inspect for cuts abrasions or burns e Inspect the positive and negative coil terminal wire connections Because the MSD is a Capacitive Discharge ignition and it receives a direct 12 volt source directly from the battery there will not be voltage at the coil positive terminal with the key turned On During cranking or while the engine is running very high voltage will be present at the coil Do not connect any test equipment to the coil positive or negative

13. PTERS If your vehicle does not operate correctly or if you experience a no run situation you probably need an MSD Ignition Adapter Some vehicles with electronic fuel injection systems may require an MSD Ignition Adapter to run properly This is because many of these systems use the same trigger source to operate the MSD the tachometer and the fuel injection This results in a voltage signal that is too low to accurately trigger the fuel injection If your vehicle s engine starts and then shuts off after a short period of time or the check engine light turns on then your vehicle will require an Ignition Adapter An MSD Ignition Adapter PN 8912 PN 89121 or PN 8917 will usually remedy the problem The chart below lists most of the vehicles that require an Ignition Adapter It is very important that the Adapter s be installed at the same time that the DIS Ignition is installed to prevent activation of the check engine light On OBD II equipped vehicles resetting of the check engine light requires special computer diagnostic equipment On vehicles not listed install the DIS Ignition before purchasing the Adapter to see if the ignition will operate properly without the Adapter s INSTALLING THE PN 8912 IGNITION ADAPTER The number of adapters required is determined by the number of cylinders on the engine Four cylinder engines will require one Adapter 6 and 8 cylinders require two Attach the PN 8912 Adapter as shown in Figure 14 If you st
14. TIONS 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 The MSD Ignition features a capacitor which is quickly charged to 460 480 volts and stores it until the ignition is triggered With the CD design the voltage sent to the coil is always at full power even at high rpm MULTIPLE SPARKS The MSD Digital DIS Series Ignition produces full power multiple sparks for each firing of the spark plug The number of sparks that occur decreases as rpm increases however the spark series always lasts for 20 of crankshaft rotation Above 3 000 rpm there is simply not enough time to fire the spark plug more than once so there is only one powerful spark REV LIMITER The MSD DIS 2 and DIS 4 Ignitions are equipped with a built in adjustable Soft Touch Rev Control This rev limit feature can be adjusted in 100 rom increments using the program switches on the ignition s end panel The Soft Touch circuitry provides a smooth and accurate rev limit by dropping the spark to individual cylinders The Soft Touch produces a load free rev limit that
