If you've got an older Ford or New Holland tractor—think models like the 4600, 4610, 5600, 5610, 5900, 6600, 6610, 670, or 6710—and the battery isn't charging or you're seeing voltage spikes, the regulator might be shot.

This is a new 12V voltage regulator from Reliable Aftermarket Parts.

Part number M5-228A.

It's a direct replacement part, one piece.

Keeps your charging system in check so the battery doesn't overcharge or undercharge.

Simple install, usually mounted near the alternator or generator.

Keeps that old iron running right.
