The RMS020-107179 is a brand new MOSFET voltage rectifier regulator, built to replace the diode-style unit fitted as standard and to stop the cycle of repeat regulator failures. MOSFET regulation runs considerably cooler than every OEM diode-style regulator, and this unit also carries overheat protection - rather than burning up, it simply switches off for a while and cools down. It is a direct replacement for the original, plug-and-play and easy to install, with no assembly required.
Compared with a traditional shunt regulator rectifier the benefits are practical rather than theoretical. There is less load on the stator, which means less work and less fuel used. The power reaching the battery is steadier and smoother, which extends battery life and preserves cold cranking capacity. Removing stator load frees up engine power, and switching the stator coils on or off optimises power delivery. The unit is rated at 50 A / 500 W maximum charging current with a minimum charging voltage of 14.5 V plus or minus 0.5 V, uses higher grade electrical components, has an improved heat sink, and every unit is tested before it ships.

Frequently Asked Questions
Does this fit without modification?
Yes. It is a direct replacement for the original unit - plug-and-play, direct fit and easy to install, with no assembly required. Check the 69 mm fixation hole spacing and the two-plug, five-pin layout against your existing part if you want to be certain before ordering.
What is included?
The MOSFET voltage regulator rectifier unit, tested before dispatch. No assembly is required and no additional parts are needed for a standard replacement.
How do I know my old regulator has failed?
Check the voltage at the battery with the engine running. A healthy charging system should reach at least 14.5 V plus or minus 0.5 V and hold below roughly 15 V. If the reading never climbs above resting battery voltage, or if it climbs past 15 V and boils the battery, the regulator rectifier is the usual culprit. A regulator casing that is too hot to touch after a short run is another strong indicator.
Why choose MOSFET over the original diode-style regulator?
A MOSFET regulator runs much cooler than a traditional shunt unit, and heat is what kills regulators. It also puts less load on the stator, so less work is done and less fuel is used, delivers steadier and smoother power to the battery, and includes overheat protection that shuts the unit down temporarily instead of letting it burn out.
