Voltage Regulator Upgrade

The Gen 1 voltage regulator / rectifier is a common failure point. I've had failures of the OE unit on two different bikes at around 30K miles. So I replaced the second one with a much more robust unit from a Honda CBR1000RR. Details and pictures are here:

Re: Voltage Regulator Upgrade

Yup. Many of us have done the same with a CBR R/R or a GSX-R R/R. Mine was with the GSX-R unit a year ago.

Re: Voltage Regulator Upgrade

Best R/R on the market today is the Shindengen FH012AA used on the late (06+) Yamaha FJR, R1 among others
It is a MOSFET controlled device rather than the crude SCR type and a 50A rated device.
MUCH better voltage regulation and runs cooler too.



These are starting to show up on the EBay market - there are many other bike models, simplest check is to use something like Ron Ayers to find all the match models. (Even Grizzly ATV uses it)

The connector plugs are quite different of course - have been unable to find a source for these - but simple female spade terminals push directly over each of the pins.
The best connection method is to run the output leads directly to the battery (the + via a 30A fuse)

Re: Voltage Regulator Upgrade

I'm running on a '04 GSXR750 R/R (or something like that) for probably longer than a year. Checked the charging voltages about a week ago and it still reads about 14.5V @ 5k RPM. But if I can find one of those that D'Ecosse is talking about, I'd go for that instead. Unless it's realy expensive. The GSXR R/Rs can be had for under $50 on ebay.

That's about the going rate for the FH012 - sometimes less. Even brand new from a discount on-line parts source, these are in the $128 range - cheaper than after-market offerings!

I just picked one up for $32 plus shipping and one of my friends paid similar. The first one I bought was $50. It's like anything else on EBay, just need to shop around, be patient & be sharp.

I wouldn't advocate going out & doing this for the sake of - but if/when you do have a faiulure, this is the one to consider.
Although having said that have converted two of my own bikes

Re: Voltage Regulator Upgrade

FYI to anyone else reading this thread in the future. The '95 YZF-R1 regulator looks exactly like FH012 from the top. But when you look at it from the side, you suddenly notice that the heatsink fins are like 3" long. This thing is freakin HUGE and heavy. It's part# FH011AA or FH011 for reference. There is no way this thing is going to mount in the original stock location. I'll have to rig it under my seat somehow.

Now that I have it in my hands, I can see that it's physically a lot taller than the FH012.

Re: Voltage Regulator Upgrade

Old regulator on the left. New '05 R1 regulator on the right.
The pic doesn't show how much taller the R1 regulator is. But it's a HUGE difference.


Here are the R1 regulator's male spade pins and the female spades I'll use to attach to it with.


The 14-16 awg female spades worked great. The dark blue and red smaller awg female spades are too small.


Temporary mounting location.



The results are that the old stock regulator had the battery at 12.4 volts with the bike running at 4K rpm. And after just 60 seconds of this, the old regulator was too hot to touch.
The new R1 regulator had the battery at 14.1 volts at 4K RPM's after a five minute ride, and was cool to the touch.

So far, other than needing to find a new mounting location.... I'm pretty happy.
The R1 regulator cost hardly anything from Marcel at www.gotmotoparts.com . He's an ex WSMC and AMA racer and a good guy. Got the part in the mail two days after I ordered it. He's got tons of bikes he's parting out on the website.

Re: Voltage Regulator Upgrade

This one is going to be locked down in the FAQ section as soon as activity ceases on it.

Great post and excellent writeup!

Re: Voltage Regulator Upgrade



Exactly as I mounted my FH012 CZ Eddie - but the *12 model is MUCH more compact. I would recommend against the FH011 model simply because of its physical size but nice job of installing .
Also although the smaller spade 14-16ga terminal is a more compact fit in the connector, try to stuff a 12ga wire into it to get less loss.


The FHO12 can be found on 07+ R1's, 06+ FJR, and a bunch of other late model Yamahas incl some snowmobiles, ATV's etc.
The OEM Yamaha part number is 1D7-81960-00-00
You can find all the models its used in by checking the RonAyers Cross Reference - just enter the part number and go.

So once you find one that looks like it on EBay, check the year & model against those in the list to validate.
I simply use a wide range "yamaha Regulator" search & then narrow down by the image.
