Product Description

The Electronic Points Box is responsible for controlling the Pro Mag 44’s energy, such as the special long duration spark and quick rise time. The magnetic pickup in the generator delivers the trigger signal and the Box takes care of the rest.

The MSD electronic circuitry, which replaces what breaker points attempted to do, releases the power of the generator to the coil instantly and at full power. No other magneto can match the Pro Mag in rise time! The coil instantly produces an incredible shot of voltage to ionize the plug gap then the current takes over ensuring that the nitromethane is ignited! The Electronic Points Box keeps the electricity flowing across the plug for a full 26° of crankshaft rotation ensuring complete combustion.

MSD offers two Pro Mag 44 Electronic Points Boxes. The PN 8145 is the standard Box while another is offered with MSD’s famous Soft Touch Rev Control circuitry. This Box, PN 8147, lets you select an rpm limit to help protect the engine in event of driveline failure or excessive wheel spin.

A strong cast aluminum housing provides a solid mounting foundation for all of the electronics as well as a very good heat sink in both Boxes. For protection against 300 mph vibrations, the circuits receive a heavy duty coating of Humi-Seal compound which secures the electronics. Special 4-pin Deutsch connectors lock and seal the wires to the generator. Vibration Mounts are also supplied.
