ESR is a superior replacement regulator/rectifier for the unreliable OEM unit.
This VR is built using a high quality 4-diode rectifier bridge, and the latest generation voltage control circuit as well.
The housing is shaped like the OEM regulator and is built to be a very efficient heat sink. The connectors and leads are of the highest quality and are direct plug-ins to the stock harness. This unit runs a lot cooler than the OEM regulator, and will give you a tightly controlled output voltage at all RPMs resulting in always having the optimum charge rate for the battery.
