MOSFET Voltage Regulator Rectifier - RM30515
Harley Davidson Sportster 883 and Sportster 1200 - 2014-2022
A brand new MOSFET voltage rectifier regulator for the 2014-2022 Harley Davidson Sportster 883 and Sportster 1200. Stop burning your regulator rectifier - it is time to update or replace your voltage regulator with the advanced MOSFET type. A MOSFET unit runs cooler than all OEM diode style regulators, and this rectifier has overheat protection: rather than burn up it will simply turn off for a while and cool off before returning to normal operation.
It is a direct replacement to your original unit, plug-and-play and a direct fit, so installation is easy and no loom modification is required. The quality exceeds the OEM equipment, with a higher grade of electric components, an improved heat sink and improved charging capabilities. All shipped products are tested before dispatch. This unit replaces Harley Davidson OEM part number 74700012, so checking the number on your existing regulator is the fastest way to confirm fitment.

Frequently Asked Questions
Do I need to modify the wiring?
No. It is a direct replacement to your original unit and is plug-and-play, so it is a direct fit with easy installation. The unit uses 2 plugs and 4 pins, and the fixation holes are 80 mm apart centre to centre to match the original mounting points.
What is included?
You receive the RM30515 MOSFET voltage regulator rectifier, measuring 66 mm wide by 110 mm long by 41 mm high. All shipped products are tested before dispatch.
How do I tell whether my old regulator rectifier has failed?
With the engine running, a working charging system gives a minimum charging voltage of 14.5 V +/- 0.5 V at the battery and holds open circuit voltage below 15 V. A battery that will not stay charged, or a reading that sits above or below that window, usually points to a failed regulator rectifier. Melted or discoloured connector pins are a further indicator.
Is this the same part number as my original Sportster regulator?
This unit is supplied as RM30515 and replaces Harley Davidson OEM part number 74700012. If that number appears on your existing regulator, this is the correct replacement. It is an aftermarket part; the OEM number is quoted for reference only.
