High quality great price. I’m very happy

By   on  Verified Purchaser

Picture shows machined edges black / aluminum fins the one I received is all black. It feels and looks like high quality materials and wires. It mounted right up and works like a charm. Idle at 13.5 volts a little more rpm and it’s a steady 14.2 volts. I’m very happy the VR fixed my charging issues. I was not looking forward to a stator and rotor replacement. Thank you. 1994 Harley Davidson FXSTS Springer Softail

Rectifier

Bought a rectifier and it was self explanatory to install. The battery was dying while riding and after the new part I can ride for hours without getting scared that I’m gonna be stranded on the side of the road.

Regulator

By   on  Verified Purchaser

Arrived quick easy install and work amazingly!


Awesome product!

By   on  Verified Purchaser

Just what i needed to fix my charging issue on my FXDLS, battery light came on and using my FP3 i saw my voltage was under 12V and dropping so the bike essentially killed my battery since it wasnt getting the correct current. Ordered this up, when changing it out this one feels heftier than the OEM one making that one feel cheap in comparison. It bolted tight up as its supposed to and worked like a charm.


Perfect replacement

By   on  Verified Purchaser

Perfect replacement for the stock part. I originally went with an eBay special that burned up in two months and it never seemed like I was getting the needed power out of it. Great part for a great price.


Awesome!

By   on  Verified Purchaser

Received my parts within a couple of days of ordering them. Exact match. Extremely satisfied!

Perfect

Fast installation, couldn't be easier. High quality and voltage output is right in spec.


Regulated Voltage

By   on  Verified Purchaser

After a couple of other repairs to my little Red Sportster, the test ride proved a little hairy about dusk when she started sputtering. I had thought the light was not very bright and suddenly realized why. Turning off the head light wasn't the best idea that time of day but it got me home. This regulator showed up quick, same as the turn signal module I ordered same day. It fit perfectly with the proper length output wire. It even had a ring connector and shrink tube. I went with my own yellow ring Stakon but I appreciate that they included a connector if I had not had my own insulated one.


Roadglider

By   on  Verified Purchaser

Received the Voltage Regulator when it was promised and it was packed nice and tight. Got it in perfect condition, put it on the Glider and it solved my electrical problem!

Questions & Answers

Ask Question

Will this work with a lithium ion battery?

It depends on the type of LiFeO4 battery it is that you have. If it's a good one that has built-in battery management system, then you should have no problem using this R/R on your machine.  We recommend you examine the battery that you have on your bike to be sure it doesn't have any special requirements. Generally speaking, if the battery works with the OEM regulator, then you shouldn't have any trouble with this, or any other replacement regulator that's built to provide power at the same specs as the OEM unit you're replacing.

Answer Question

Will this regulator work with an agm battery?

Answer Question

What's the difference between a cheaper and an expensive voltage regulator? Will this one fit on my 98 Harley Dyna FXD? Thanks

Without knowing exactly what voltage regulators you're referring to, I can't say for sure what those differences could be. I can tell you that, these solid-state regulators from Drag Specialties provide a more consistent 12V power output than the stock unit on most bikes, or any other conventionally-gated aftermarket unit on the market. If you have a machine that's running a lot of aftermarket electrical parts, you can't go wrong with a solid-state regulator. As for fitment, if you were to choose the 1998 Harley Davidson FXD Dyna Super Glide solid state regulator from our fit guide, you'd receive the correct regulator to fit your bike. We guarantee it!

By Staff
Answer Question

Yes, we do sell a solid stator regulator for the 2007 Harley Sportster 883 Just choose the 2007 XL883 Sportster 883 from our fit guide and you'll get exactly what you need. We guarantee it!

By Staff
Answer Question

How can I check my old voltage regulator to see if it is good or bad

One of the easiest ways to test your regulator/rectifier is to check the voltage at your battery terminals with the bike running. Simply start up the bike, rev it up, and the voltage should go up to 13.5-14.5 VDC. If you find that battery voltage is above or below that range by a few tenths, the regulator isn't working correctly. Your bike's service manual will also give you an exact test method as well as the exact acceptable voltage output ranges. If you don't have a service manual for your machine, we do have a variety of Clymer Shop Manuals on our website to help you determine how well your bike's charging system is work.

By Staff
Answer Question

what is the warranty on this part?

Drag Specialties' Solid-State Regulators are covered by a one year manufacturer's warranty. If, at any time during that period you have a problem with the unit, just give us a call and we'll get you sorted out.
