Brand new Mosfet voltage rectifier regulator. 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 will simply switch off for a while and cool down before resuming normal operation.
This is a direct replacement for your original unit. It is plug-and-play and a direct fit, so installation is straightforward with no modification to the loom. The quality exceeds the OEM equipment, with an improved heat sink, better charging capability and a higher grade of electrical components throughout. All shipped products are tested before they leave the warehouse.

Frequently Asked Questions
Will this fit without modifying my wiring?
Yes. This unit is a direct replacement for the original regulator rectifier and is plug-and-play, with two plugs and seven wires at 170 mm. No assembly or wiring modification is required. The fixation holes are 80 mm centre to centre, matching the original mounting.
What is a MOSFET regulator and why choose one?
A MOSFET regulator uses transistor switching instead of the shunt diodes used in older OEM style units. It runs cooler than all OEM diode style regulators and includes overheat protection, so instead of burning out under sustained load it simply switches off, cools down and resumes. It is fitted with an improved heat sink and a higher grade of electrical components.
How do I know my old regulator rectifier has failed?
Typical symptoms are a battery that will not hold charge, dim or flickering lights that change with engine speed, a charging voltage that never reaches around 14.5 V at the battery, or a regulator body that is discoloured, melted or too hot to touch. Compare your measured charging voltage against the 14.5 V +/- 0.5 V figure for this unit.
What output can this unit handle?
The maximum charging current is 50 A / 500 W with an open circuit voltage of 15 V, and it is rated to operate between -20 C and 85 C. Every unit is tested before it is shipped.
