Universal Mosfet Regulator Rectifier - Up to 350 Watts
Universal fitment, 75 mm between fixation holes - part number RM30511H
This is a universal Mosfet voltage regulator rectifier able to handle up to 350 watts, with 75 mm between the fixation holes. It is not model specific, so it is the unit to reach for on a rebuild, a custom build, or a machine whose original regulator is no longer available. It arrives with 660 mm of wire on seven leads, which gives room to site it where there is clean airflow rather than being tied to the original mounting point.
The reason to fit a Mosfet unit is heat. This regulator runs at lower temperatures than traditional diode style regulators, and it includes overheat protection that disengages the unit rather than letting it burn out. Heat dissipation and charging performance are both improved over original equipment, premium electrical components are used throughout, and every unit is tested before it is shipped. Installation is plug-and-play once the leads are terminated to suit your loom, with no assembly required.

Frequently Asked Questions
Will this fit my machine?
This is a universal part rather than a model specific one, so there is no fitment list to check against. Compare the specifications above with the unit you are removing - in particular the 75 mm hole spacing, the seven wires, and the 350 watt capacity against the output of your charging system.
What is included?
The universal Mosfet regulator rectifier with 660 mm leads. No assembly is required, and no connector is specified for this part, so the leads are terminated to suit your own loom.
How do I know my old regulator has failed?
Measure the voltage at the battery with the engine running. A healthy system settles at around 14.5 V. A reading that stays at resting battery voltage points to a regulator that is no longer charging, while a reading above 15 V points to one that is no longer regulating and is overcharging the battery. A regulator that is scorched, swollen or too hot to touch has usually already gone.
Where should I mount it?
Anywhere the 75 mm hole spacing can be used and the unit gets airflow across its heat sink. The 660 mm of wire is generous enough to move the regulator away from the original position if that position ran hot, which is a common cause of repeat failures.
