MOSFET Voltage Regulator Rectifier - RM30342
Harley Davidson Sportster 883 and Sportster 1200 - 2008-2013
A brand new MOSFET voltage rectifier regulator for the 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 also carries overheat protection: rather than burn up it simply turns off for a while and cools off.
This is a direct replacement to your original unit. It is plug-and-play and a direct fit, so installation is easy and no rewiring is needed. 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. It replaces Harley Davidson part numbers 74546-07, 74546-07A and 74711-08, so the number stamped on your existing regulator is the quickest way to confirm you are ordering the right unit.

Frequently Asked Questions
Will I need to modify my loom to fit this?
No. It is a direct replacement to your original unit, plug-and-play and a direct fit, so installation is easy. The unit has 2 plugs, 4 pins and 4 wires with 250 mm of wire length, and the mounting holes are 82 mm apart centre to centre.
What is included?
You receive the RM30342 MOSFET voltage regulator rectifier, measuring 68 mm wide by 96 mm long by 37 mm high. All shipped products are tested before they leave us.
How do I tell whether my existing regulator rectifier has failed?
Measure the voltage at the battery with the engine running. A healthy system reaches a minimum charging voltage of 14.5 V +/- 0.5 V and keeps open circuit voltage below 15 V. A flat battery, dim lighting, or a reading that sits outside that range typically points to a failed unit. Melted or blackened connector pins on the old regulator confirm it.
How do I confirm this is the correct part for my Sportster?
Check the number on your original regulator. This unit replaces Harley Davidson 74546-07, 74546-07A and 74711-08. If any of those numbers appear on your existing part, this is the right replacement. All item pictures are accurate, so you can also compare the item against your original part.
