GENERATOR SUPPORT

In some applications it is recommended that a generator support bracket be fabricated. Due to the

variety of mounting applications, MSD does not offer a single mag bracket. For applications using

two Pro Mags it is recommended to use the Dual Mag Stabilizer Bracket, PN 301821-0004 from RCD

Engineering, wwwRCDengineering.com.

Note that the connectors have numbered terminals. Match the color wire with the position as follows:

12 and 20 Amp

44 Amp

#1 Violet

#2 Green

#4 Yellow

#3 Black

#1 Violet

#2 Green

#4 Red

#3 Black

WIRING AND CONNECTORS

MSD uses Deutsch connectors with the Pro Mag. These connectors should be inspected due to

frequent disconnecting. Lightly pulling on the wires near the connector will make certain they have

not worked loose. The connectors can be disassembled as follows:

1. Remove the orange wedge lock with a small flat blade screwdriver.

2. Pry the spring lock back to unlock the wire, and pull it through.

3. Inspect the wire crimps and reassemble.

MSD offers a special kit consisting of connectors used with the ProMag 44. The kit PN 8124 is de-

signed for field repairs.
