 Johnny Bridges Posted:

I have had to replace the voltage regulator on this old machine a couple or three times over the years & this one did the trick, was a good price & got here way faster than my Harley dealer could get it.

 Roylaccone Posted:

It came quickly, I installed it and started it right up now I am out enjoying the bike again. Thanks J&P Cycles.

 vincec57 Posted:

This is a replacement for one that went bad after a month. Yet to be seen if that was just a bad unit

 decherd236 Posted:

Perfect product hooked right, would order again without hesitation.

 1996flstn Posted:

 carter487 Posted:

Quality product, prompt shipping as always. Thank you.

 Bulldodge Posted:

Seems to work well. Only had to replace my old one because it failed. Looks good since I am trying to put my bike back to black and not chrome.

 mpdonovan49 Posted:

Quick arrival, as described and easy install.

 simpleman Posted:

Had to trim the plug a bit but not a problem. Ordered after 5 pm and still received next day!! Great service. Great price.


Great part,fit perfect.Gave me more voltage which helped the turn signals work properly.

 dhcguitars Posted:

Good fitament, easy to install on my '91 FXSCT, & is doing it's job.

 Jondo Posted:

Nice long wire to the breaker but it is aluminum and not copper. Really tight fit to mounting bolts on my 99 fatboy. Had to bend bolts in a tad and tap regulator on.

 plumloco81 Posted:

 BE-BES Posted:

 shovel89 Posted:

grate buy

 Tommich6999 Posted:

good price, fit well, solved my charging problem!

 sprinnger Posted:

looks like the dead stock unit it replaced. works good for my application

 jaredshearer Posted:

The regulator works well. I have a 1991 Heritage Softail, and the only reason I took one star off is that I had to dremel out one of the mounting holes to get it to fit over the two studs. It took an extra two minutes. Not a big deal.

 mreynaud Posted:

perfect fit. Costs about half of OEM. My son has been using for 6 months now with no problems.


The quality is excellent and works great.

 mac99flstc Posted:

This regulator looks and fits just like the original. It arrived only 2 days from order date and installed in 15 minutes. Charges better than the original. Wow, what great service. Thanks.

 wally73 Posted:

 tamitchell Posted:

I received the wrong part in the right box,When i called i spoke to a supervisor who immediately took care of the situation and over nighted the correct part to me.outstanding customer service,thats why i will always shop j&p. Thanks

 glvbref1 Posted:

great product, fits like a glove...

 ashleyking81 Posted:

It's what I needed and it works!

 samsherrill Posted:

The installation was perfect! Notes: -If you have a long oil filter that cover the plugs to the stator you do not need to remove filter. Gently "roll" plug off towards the front of the bike. -The grounding slot for ground wire gets tapped with the current screw from the old regulator. -Following the wire back to the main breaker can be tricky. Take your time and replace all old zip ties and watch out for areas that will cause rubbing. Be careful replacing the the gas tank you'll want to double check connections at switch panel to make sure everything is plugged in correctly. I hope this helps.

did the job very fast shipping

 ericlentz Posted:

Does the job. Posted:

A perfect replacement.

 j_mckamey Posted:

Great product. Was worried a bit that the eye on the end of the breaker wire wasn't installed but once I began installing I understood why. You have to thread that wire through a series of small clips. Solved the low voltage problem.

 mirro16 Posted:

Regulator has been on since early June and have not had a problem, unit seems good to me. Time will tell. J&P rocks great customer service and fast shipping.

 davidwcowan Posted:

 survivor55 Posted:

Solved the problem.

 darkgouda Posted:

Just like OEM good length for battery cable.

 leftydogbob Posted:

Competetive price, worked as expected, and the store in Anamosa, IA has big truck parking. Great place to stop in and visit with the friendly and helpful staff.
