Customer Reviews

HardDrive voltage regulator

By Paul R. on  Verified Purchaser

As far as fit, the mounting holes had to be filed a little to fit the stock mounting studs on my '78 Sportster- not bad- it did not fit onto the studs as received. Once mounted, and generator polarized, it works very well so far. It's November here in Michigan, so not a lot of miles on since getting the charging system working. This part matches the look of the stock voltage regulator that the bike came with. Connections fit good.

Thank you

Thank you it was just what I needed

Voltage regulator for Harley Davidson

By Gary F. on  Verified Purchaser

Removed and replaced the VR with no issues. Replacement VR works just fine.

Great Part!

By Tomcat 75 on  Verified Purchaser

This took care of my Harley Ultra's charging issue. Easy fix for something that I feared might involve harder to access work.

Thanks

Got my Dad's 1970 FLH running after 18 years in storage.
