The following test will determine if your MSD is producing a spark. White Wire Trigger: If you are using the White wire (points or electronic amplifier) of the MSD to trigger the ignition, follow these steps. Make sure the ignition switch is in the Off position. Remove the coil wire from... (more)
This section covers the installation of the MSD 6A, 6AL, 6BTM, 6T and the SCI Ignition Controls. These Ignition Controls feature capacitive discharge circuitry and multiple sparks. They will install to most vehicles with a 12 Volt electrical system and a distributor that is triggered with points,... (more)
This section covers how to wire redundant ignition systems featuring the MSD 6TN, 6ALN, GM Heavy Duty Ignition and the 6 HVC Professional Ignition. These ignitions are designed primarily for circle track and road course racing where running a redundant ignition system is commonplace. These... (more)
This section covers the MSD 7AL-2 and 7AL-3 Ignition Controls. These ignitions share the same wiring to run the vehicle, but the 7AL-3 has several optional accessories that can be connected. The 7AL-2 has a single stage rev limiter while the 7AL-3 has a Three Step Rev Control along with other... (more)
The MSD 5 and Blaster Ignitions are inductive ignitions which enhance the spark of the vehicle’s stock ignition. The MSD 5 is a multiple spark ignition, while the Blaster is a single spark, long duration design. Both are designed for entry level and budget build-ups and can be triggered with... (more)
This section covers the MSD 8 Series Ignition Controls. The MSD 8, PN 7800, is a race only ignition system. The MSD Pro Power Coil, PN 8201 is the only coil recommended for the MSD 8 Ignitions. A current filter, PN 8830, is also recommended to help suppress EMI noise and voltage spikes.... (more)
This section covers the MSD 10 Ignition Control. The MSD 10, PN 7500, is a race only ignition system and is unique in that it incorporates two ignition coils. The MSD Pro Power Coil, PN 8201, is the coil responsible for the Capacitive Discharge side of the ignition while the Pro Power... (more)
This section covers the MSD Digital-6 Plus and the Digital-7 Plus. These ignitions share the same wiring and functions. The main difference is that the Digital-7 Plus produces more spark energy and is intended for racing applications only. The 6 Plus is designed for street/strip use and... (more)
This section covers the MSD DIS-2 and DIS-4 line of Ignition Controls. The DIS-2 Ignitions can be used on 4-cylinder engines equipped with two dual output coils. The DIS-4 Ignitions can be used on 4, 6 or 8-cylinder engines equipped with up to four dual output coils. They will accept... (more)
