Quality replacement Regulator/Rectifiers.

ESR444 is a high quality regulator/rectifier that replaces the OEM regulator on various models.

Our ESR444 offers superior performance in the same plug-in package as the OEM unit. We utilize our newest power circuit design and combine it with a highly efficient heat sink. The connector is identical to OEM so it plugs right in.

ESR444 offers a more stable battery voltage, a perfect charge rate for the battery and a cooler running unit which vastly improves reliability.

This is a great upgrade for the stock unit. ESR444 is supplied with a full one year warranty.

Please Note:

1. All electrical components must be fitted by a qualified technician.
2. Before fitting electrical components ensure the root cause of the original failure has been addressed.
3. The absence of either of points 1 or 2 above will void any warranty.
