Wiring instructions for the MDA/MDP/ 444 alternators, compared to 22SI

MDA wire thumbThere's been some confusion about the wiring configuration for the MDA / MDP / 444 alternators. These units were initially marketed as direct, drop-in replacements for the Remy 22SITM alternators. However, the wiring configuration is slightly different, and if you're not careful this can create a problem.

The attached technical bulletin (TSB-1042) shows how to wire up the Leece-Neville 444 style alternator, and even shows the wiring on a 22SITM for comparison.
