The Pro-Mag 44's Electronic Points Box takes the trigger signal from the generator's magnetic pickup and controls the long-duration spark and quick rise time needed to ignite nitro-methane. MSD's electronic circuitry releases the generator's power to the coil instantly at full strength, keeping electricity flowing across the plug for a full 26 degrees of crankshaft rotation to ensure complete combustion. A cast aluminum housing provides a solid mounting foundation and heat sink, with all circuits Humi-Seal coated to withstand 300-mph vibration.
