Hi everyone, please read the READ READ READ section below to help with ordering. So many people after the fact email me and say I did not know I needed an adapter bracket or I needed longer cables. The READ READ READ section helps answer these questions. Also, I will not ship ship to a different address than what it says on the order in Paypal so please fix your address before ordering or I will just refund so you can fix your address.

Guy's if you email me make sure you check your scam folder. So many times people miss my answers because they don't get through.

The go to place for Shindengen Mosfet and Series R/Rs

Started in 1994, 29 years and still growing strong.

To all my awesome customers:

Please remember that the FH020AA Mosfet and the SH847 series R/R are OEM stock regulators that come on a few Production motorcycles. They have been working great on other Manufacturers motorcycles for years and are considered the go to R/R when a reliable replacement or upgrade is needed. It is up to you and only you if you want to install an upgrade kit on your motorcycle. By purchasing a kit you are taking on the personal responsibility to install the kit correctly or hiring someone to install the kit correctly and that you know that the R/R you purchased was not originally built for your motorcycle and assume full responsibility for installing it on your bike or race car.

Again, Thank you,   Jack

I only sell real OEM Shindengen FH020AA and SH847 Regulators.

   Hi Everyone, I try my hardest to give you a great kit but you need to measure to see if 3 feet of 10 gauge battery cable in the stock kits is long enough for your bike. 90% of the bikes it is, check your bike to make sure. Also, the Super kit stator connection wire length is about 12" long,  Is that enough length for your hookup? Measure to be sure. Order  longer  length right below this section if needed. Do you need an adapter bracket? Measure your mounting holes and compare them to mine.  Extra sheathing is included with 10 gauge cable add on but not for add on stator lengths, you can order sheathing down this page a bit. GSXR 600 and 750 with the R/R in the front behind the radiator need 1 extra foot of battery cable if you order a Complete kit or Super kit, not needed for the GSXR lead link. GSXR 600/750 Lead links are now available, scroll down the page.  Stator wires do not have polarity so you can hook them up in any order.  Also one other little tid bit, I have people ask me all the time that they have 2 reds and 2 greens (or black)  wires coming out of the old R/R and what do I do? Some bikes have 2 wires because the Manufacturer needed bigger gauge wire and decided to double up the reds and greens (or blacks) to carry more current.  But if you read my directions you'll find we don't use them anyway in an upgrade kit. The old power plug gets taped off and tie-wrapped safely away. No worries as everything will work just fine.  Just add my pos and neg battery cables to the battery and hook up the stator wires to mine and your done other than mounting the new R/R. Adapter brackets are available below for upgrading to any of my R/Rs. Measure your R/R mounting holes against mine as you probably won't need an adapter bracket.  Also, I'm at the shop pretty much all day now so if you need to call me it's OK.  310.766.5222  Jack

CHECK YOUR ADDRESS BEFORE YOU ORDER, Have you moved since the last time you used Paypal? Is the address correct?

I use blue  loc-tite on all my fasteners, you should too.

On a side Note:
You can not check a SH847 or SH775 with a multimeter like you can a FH020AA Mosfet. You have to use a bench test machine like the one in my videos. It's just not possible, believe me, I've tried to come up with a test.

DIY crimp or solder kits
I have real Shindengen R/Rs. 

Universal  DIY Kit with 30 ampauto reset Circuit breaker. I no longer use the Maxi-fuse set up in photo.

 The DIY kit is a crimp or solder complete regulator kit with everything you need to upgrade your Sportbike or Cruiser to a Mosfet or series R/R. If you need extra length stator or battery wiring you can add it under the READ READ READ section. Crimping cutting, stripping, soldering, installing heat shrink is all done by you to build your own custom kit. Takes a little time but when you're done you'll have your own customized by you install. Very Cool!!  Custom wire lengths are available. Now with PVC wire sheathing!!  3 feet of battery cable comes with the kit.
OK, if this is your first time soldering or your not real good at it, watch my video on soldering. Use thin solder, I use .035 or .040 solder so it flows easily. Make sure your iron on a real hot setting. If you need an adapter bracket to mount the Mosfet easily they are down below, scroll down.  Regulator dimensions are in the left side index so you can check if it is a direct bolt on replacement or not. Remember that stator leads can go any which way there is no polarity. Also, the wire I use is tin covered copper marine grade wire which solders awesome. It is not aluminum. Also take a look at my LED voltage monitors, they are awesome. Some of my 6th Gen VFR customers have said that 4 feet of battery cable total (it comes with 3 feet) and 24" of stator wiring would be better for some years of VFR.  If you need this add 1 foot of battery and 24" total stator wire length above in the add on section right under the READ READ READ section. I also have help videos to help with building up the DIY kits.

SH847 SERIES R/R KITS

SH847 series regulator picture     The SH847 is the newest R/R from Shindengen, the same people who built the FH020AA and FH012AA so you know the quality is there. I call it the stator saver as it runs the stator cooler. Perfect for street bikes and track bikes. These are 50 amp peak models that have been tested on the Rotax motored Buell and Aprilia models and have been working great. They have been running these on the 600 Ducati with no issues. I can can make these harnesses any length, check the highlighted areas above for add on wire lengths for battery and stator.  Battery cables are 36" and stator wires are 12" that come in the stock kit.


    I am only selling SH847 as a Super kit as these R/Rs are very expensive and I don't want any issues due to old or bad charging system wiring. I want to make sure this setup is rock solid in every way.  The dimensions of the SH847 are below in the PDF.

   
Remember that stator leads can go any which way there is no polarity. Also, the wire I use is tin covered copper marine grade wire which solders awesome.

    Also, if you order a SH847 I bench test them all before they leave the shop.  The SH847 is expensive and there is no returns so I make sure everyone is solid before I send them.   Suzuki will not accept warranties from me or even their own dealers. So if you buy a SH847 from me you can be sure it's ready to go! 
Also take a look at my LED voltage monitors, they are awesome.

APRILIA and Buell Rotax engine models, Most of my customers are mounting the SH847 under the inner fender. Some guys say the stock kit works fine and other add a little length to be safe. Measure, measure, measure to make sure of the lengths you may need.

6th Generation VFR need 4 feet total of battery cable and 24 lnches total stator wire and the 4 way bracket to do it cleanly. Add wire lengths in add on section above.  4 way bracket works with SH847 Stator Saver and FH020AA Mosfet. Did an install at my shop 11-27-17, worked and looked great!

  A lot of people are calling these the stator savers. The series R/Rs do run the stators cooler so in essence they do help with stator heat build up.  Besides street bikes all race bikes or track days bikes should have series R/Rs if your unplugging the headlights, not so much for the stator on these but because of the excessive heat build up that happens in the stock shunt type R/R. If you ever watchd a motorcycle race on TV and you see a bike on fire or smoke coming out it's usually a fried R/R.

SH847 is for use in MC powered race cars Too !!!! IT's the best way to go.

Here's a PDF file for the SH847 to make a template for fitment.

Make sure you measure after you print it. 100% and shut off automatic scaling worked great for me.  Jack

I make the SH847 easily available to everyone but unfortunately Suzuki say all regulator sales are final and no returns. I bench test everyone before they leave my shop to make sure they are working correctly. So be careful installing, do not hook up backwards as it can kill it.

NOTE:  You can not check a SH847 with a multimeter like you can a FH020AA Mosfet. You have to use a bench test machine like the one in my videos. It's just not possible, believe me, I've tried to come up with a test.

EVERY MOTORCYCLE FROM THE FACTORY SHOULD HAVE A VOLTAGE MONITOR

LED VOLTAGE MONITOR

YES, these monitors are completely water proof. NOTE: Do not use headlight or tailight wires for power, goes to the battery or to a fuse in the fuse box that is switched power. Some people have been going straight to the battery posts and let it flash red all the time when the bikes not running for a theft deterrent as it looks like an alarm is on. This is a HOT item!!! This should be stock from the factory on all motorcycles. My new units have been re programmed for either Shorai or stock battery use.  It has the over voltage warning now at 15.2 volts to warn and guard against killing a Lithium battery or boiling a stock battery, best of both worlds in one unit. You can drill a 14mm hole and mount it in your dash.

Crimp and Go kitCrimp & Go Kit $155.95 FH020AA


The newest kit from Jack is the Strip, Crimp & Go. I am not an advocate of using your old harness to upgrade to a Mosfet regulator  but some people need this and who I am to say no. If your harness is on a new bike, or is in tip- top condition then this kit will work great for you. You just cut off your old stator and battery connectors and strip the wires and install the heat shrinkable connectors on your stock wiring making sure you have good solid crimps. There is no directions in the kit. You just strip, crimp and go.  This kit is fast and easy but you have to do it right. 12" wires on both. Remember that stator leads can go any which way there is no polarity. Also, the wire I use is tin covered copper marine grade wire which solders awesome. It is not aluminum.
You can not order extra wire length for the Crimp and go kit.

Super bracket ADAPTER PLATE BRACKETS

I am now offering a universal mounting bracket for the ShindengenFH010AA, FH012AA,  FH020AA and SH775 regulators.  Also the SH847 bracket is now available.  Comes with bracket and stainless mounting hardware. The bolts I send are metric #6 x 1.00 mm button head allens. These fit most metric bikes. If these are not your size you will have to provide them. I also provide 1/4" threaded mounting bolts and washers for the new R/R mounting. I personally build each one in my shop on my milling machine  in the USA. These are made with 1/4" aluminum flat bar. You can trim if needed for ultimate weight reduction. The 2 way is 1.5" x 4.50" wide. slotted hole spacing can accept from 1.875" to 3.75" center to center of bolt, spacing. Now the new Super GSXR adapter plate with center hole will let 2006 and 2007 GSXR 600 and 750 owners be able to mount there new Mosfet or R/R around the corner instead of behind the radiator.  It comes with spacer and hardened bolt and locking nut to move the R/R to a better and cooler airflow area. 

Below is the new 06-07 GSXR  600-750  Bracket and hardware. This bracket is new,  I designed this as a simple easy install, the hardened through bolt is better than grade 8. Use removable blue lock tight to install I built it as light  possible for street and racing.  It can rotate it 360 degrees if needed.

The black bracket in picture is your stock R/R horn bracket, it does not come with the side mount bracket.

   Triumph T2500676 Harness
 and FH020AA Package for many Triumph models and Ducati models.
Look at the connectors and see if it they will work on your model.


This is a T2500676 adapter harness for a direct plug and play for the Triumph Triple. It may fit other Triumphs a.but you'll have to check your connector ends and see. An avid Triumph owner told me it is the same connector found on a lot of other Triumphs. Also this works on numerous Ducati motorcycles also. Check the forums .The picture of the ends should be a good indication of what it will fit. On some Ducati models the ends plug in but no locking feature. Some guys pull the old plastic connectors off the stock old R/R and put them on the Triumph lead link to get the lock back, others just use a plastic tie wrap. Either way the upgrade is well worth it for the Ducati bikes.  Adapter brackets available above.

FH020AA Mosfet is included with Triumph Harness.
