Frequently Asked Questions
Do I need to modify anything to fit this?
No. This is a direct replacement for the original unit. It is plug-and-play and a direct fit, with two plugs and two wires, and no assembly is required before installation.
What is included?
You receive the voltage regulator rectifier itself, tested before shipping. The unit measures 52 mm long by 33 mm wide by 25 mm high.
How do I know my old regulator rectifier has failed?
Common signs are a battery that will not stay charged, lights that dim or brighten with engine speed, or a charging voltage at the battery that never settles at around 14.5 V. A regulator body that is discoloured or that runs extremely hot is another indicator. Check your reading against the 14.5 V +/- 0.5 V minimum charging voltage of this unit.
How can I confirm this is the right part for my XR?
Check the OEM number on your original unit against 31400-MN1-680, and confirm your machine is an XR 600 R from 1991 to 2000 or an XR 650 R from 2000 to 2007. The item pictures are accurate, so you can also compare the connector and body shape directly against your original part.
