A brand new MOSFET voltage rectifier regulator for the Honda XL 1000 V Varadero from 2003 to 2010. It is time to update or replace a voltage regulator with the advanced MOSFET type: it runs cooler than all OEM diode style regulators, and this rectifier has overheat protection, so rather than burning up it simply turns off for a while and cools off. On a big touring twin that spends long periods at steady revs with a full electrical load, that is exactly the behaviour you want.
It is a direct replacement for your original unit, plug-and-play and a direct fit, with a 90 mm square body, 30 mm height, 75 mm between the fixation hole centres and 2 plugs carrying 5 pins and 5 wires on long 850 mm leads. The heat sink and charging capabilities are improved and a higher grade of electric components is used, so the quality exceeds the OEM equipment. All shipped products are tested. The opposite connector for the main harness side is included, as these are often melted, corroded or defective and a major cause of repetitive electrical issues.

Frequently Asked Questions
Will this fit without modification?
Yes. It is a direct replacement for the original unit on the XL1000V Varadero from 2003 to 2010, with the same 2 plugs, 5 pins and 75 mm fixation hole spacing, and 850 mm leads that reach the standard mounting position. No assembly is required. Please confirm the OEM number on your original unit before ordering.
What is included?
The MOSFET regulator rectifier and the opposite connector for the main harness side.
How can I tell my old regulator has failed?
Look for a battery that will not hold charge, a charging voltage at the battery terminals that never reaches about 14.5 V or that rises above 15 V, lights that dim and brighten with revs, and a regulator that becomes extremely hot. On the Varadero, melted or corroded pins in the harness connector are a very common finding.
Why choose MOSFET over another diode regulator?
Diode style regulators shed their waste energy as heat and eventually cook themselves. A MOSFET unit runs cooler and adds overheat protection, turning off briefly to cool down instead of failing, which is why it is the sensible upgrade rather than fitting another unit of the original design.
