Frequently Asked Questions

Does this fit without modification?

Yes. It is a direct replacement for the original unit and is plug-and-play with no assembly required. The single 2-pin plug and 140 mm wire lead match the original, and the two fixing holes are 60 mm apart centre to centre. Confirm your existing unit carries OEM number 82M-81910-A0-00 before ordering.

What is included?

The voltage regulator rectifier unit itself, complete with its connector and wiring. Every unit is tested before it is shipped.

How do I know my old regulator has failed?

A working charging system should hold the battery at the minimum charging voltage of 14.5 V +/- 0.5 V with the engine running. A reading that stays low, or one that climbs above the 15 V open circuit figure, points to a failed regulator rectifier. Before fitting a new unit, check the AC output of the stator, replace any burned or corroded connectors and repair melted wiring, otherwise the same fault will return.

Is this an AC regulator or a DC unit?

This is an AC voltage regulator rectifier. It has two wires running to a single 2-pin plug and is rated at a maximum charging current of 20 A / 150 W, with an operating temperature range of -20°C to 85°C.
