Msd 3 Step Wiring

Msd was the first company to develop and offer the multiple sparking capacitive discharge ignition for engines.

Msd 3 step wiring.

I figure red wire goes to transvreak wire but what about the blue. They feature three built in rev limiters one for burnout one for starting line launch and one for high end. The 3 step module selector switches between three modules. As an example we ll use a drag car with a three step module selec tor plugged into the rpm socket of a 7al 2 ignition.

The terminal strip on the left side of the box is responsible for the power leads and the coil wires. Begin wiring the msd by connecting the wires responsible to run the engine. It shows the components of the circuit as simplified shapes and the capacity and signal contacts amid the devices.

The 2 step module selector switches between two modules. These selectors use the msd plug in rpm modules. Msd 3 step module selectors are designed for great versatility. 2 speed powerglide and 7al 2.

Never used or wired a 3 step but how do you wire the red and blue wire. The line of msd 6 series ignitions are the most popular aftermarket ignitions in the world due to our race proven performance on the track and our reliability on the street. The different rpm modules are activated when 12 volts are applied to a corresponding wire. By connecting one wire to the line lock circuit one module will be activated during the burnout.

The selectors work with either a soft touch rev control or any msd timing control that uses plug in modules.
