Honda CBR600RR Mosfet Rectifier Mod

[Stanleybobly]

My First Post here, Hi All Folks !!

Finally did my rectifier mod. This time not with an Goldwing rectifier but I
used an Honda CBR 600/1000RR Mosfet rectifier (MY 2007- and on)
bought it from a breaker on Ebay. Price € 60 + € 15 shipping (may 2010)
Now (2012) the prices are risen, breakers do know the demand

Same manufacturer as the original and 90% of most bikes: Shindengen model FH008 , ( 35 A ) FHxxxx stands for Mosfet.
Instead of SHxxxx old technology, which dispose a lot heat.
Size of it is exact the same as the original and it fits perfect. Looks are far better than the old one.





connectors are from (GM) Delphi metri-pack 280 (waterproof) and rated at max. 30A. (note wrapped one side with tape to prevent it from scratching my frame.)

Left the white connector unused < In my case cutted it and shrinktubed (glue) it.
additional Auxiliary can be connected here, as its a switched wire.







results:
Headlights OFF
original rectifier , 13.6 Volt @ idle
Mosfet rectifier, 14,33 @ idle = original (thin) wiring harness.
14.45 @ idle = Eastern Beavern/ Metripack connectors wiring direct to the Battery



With headlights on @ idle:


voltage at 4000rpm.


update: 4-2011
Wired the FH008 directly to the battery with thicker AWG 12 / 2,05mm/ 3,31mm² wires & metripack 630/280 connectors .

idle with headlights off:

Heat problem? :
the original you would burn your fingers by touching it.
this one, Does even build HEAT, nice warm but burning.... now way

Nice mod... how many wires does this use? Same as Capo or same as goldwing?

Well done!
An italian friend installed the Shindengen mosfet regulator model FH012AA (50A!) and he is actually happy with it.
Problem is it doesn't fit right cause it's bigger, so he had to cut the side panel.....
I think I will follow you on this mod!

Used the same wiring from the Capo,
3 from the alternator,
4 to the battery threw the originale wiringharnass (2+, 2-) wrapped it together in to 2 wires.

Maybe in the future, I'll swap the skinny wires in to thick ones.

the Fh012 is way to big, to fit indeed.

Neat looking job. Hope your new connectors last longer than my PosiLocks did. Interesting to see the voltage drop nearly half a volt with the headlight on. I guess this is due to the lack of voltage sensing wire.

[Stanleybobly]

Metri-pack 280 connectors are rated max 30A current stream. after that the fusebox with an 30A fuse wil kick in.
posi-lock ain't made to overtake such a current.

...posi-lock ain't made to overtake such a current...

Can't argue with that!

Sellers on Ebay are awakening :

Sale:

Genuine Regulator / Rectifier for CBR600RR 07- 09 Models

Excellent undamaged working condition

Ideal for replacement / race spares / special project

CODE IS FH008EE - Regulary used as a replacement for SVs, Aprilias etc

so grab yourself one, before the prices sky rocks it.
bought mine at € 60 used.
Ebay link

I've been lazy lately, will be posting a nice pic of my Voltage at 4000rpm
still going strong with the mod, bike starts far better than before.

Thanks Stanleybobly for the info on fitting an alternative R/Reg unit.....

....I've just taken the plunge and ordered an FH012AA from an 07/08 R1 .... the unit won't fit where the standard R/Reg goes, so this is what I'm proposing doing.



An aluminium plate mounted where the ABS modulator unit mounts (RR is none ABS but has ABS subframe, wheels etc ... go figure!). It provides plenty of room below the coils and is still well clear of the exhaust and rear shock.

This unit is mosfet, so should run cooler, it's also a 50A unit instead of 35A and with only 5 wires to bother with it'll be neater to install.

I'm running new 12 guage wire from the alternator direct to the R/Reg (1 connector only) and the earth will be run to the main earth point on the engine (connection to battery via largest earth line available) and the live will be fed via a waterproof 30A fuse to the starter solenoid terminal ( largest live cable directly to the battery).

With the old R/Reg slot empty, I've decided to fit an 80x80 high-flow fan in it's place. The unit only draws 0.5A so I may leave it permanently on (via key) - or maybe fit a thermal switch, I'll wait and see if it works first!

Sadly though, I couldn't locate the Furukawa connectors anywhere in the UK, so I've ordered from the USA .... It'll take me a while to finish the plate so I'm in no rush.

These are the websites that where invaluable for info and parts:

My First Post here, Hi All Folks !!

And quite a good post at that. If I'd known about these mosfet units back around '04 when I installed the Gold Wing unit, I'd have chosen this way instead.
Much less heat, and more efficient. And I really like those connectors!

Hi moto-abruzzo,

This looks a very promising & professional installation ,

My Honda Goldwing rectifier still runs too hot for my liking, although touch wood I've had no more issues, this coming winter, as well as doing the big 30K service, including removing the front Brown connector, I to want to look at making the rectifier run cooler, your idea looks good.

The plate that you are mounting the rectifier on (Aluminium) will act as an added heat sink & provide protection of the rear coils from the elements underneath.

Mounting the PC type fan is a good idea as well, I presume it will draw the hot air out from under the seat and not force cool air in, as the former would be more efficient, especially in warmer climates.

A very well thought out idea......good work .

Thanks, those mosfet unit are recently installed OEM on new bikes since 2007.
so back in 2004 they didn't exist.

@moto-abruzzo
Nice CAD Drawing.
about the fan there is no need for that. Your bike gets its airflow well enough too cool your FH012, Consider this Mosfet units don't get warm as it used to be

And about those plate acting as heatsink, no need for that, It won't be building that much heat. the FH008 has already got an alu plate behind it. Yesterday drove on the heat here , touch the unit and still didn't burn my fingers. Airflow on the side fairing does is job.....

[moto-abruzzo]

Stanleybobly .... you're probably right, why 'over egg the pudding'. I'll try it without the fan first and if it's all happy-bunnies, I'll leave it at that.

The FH012 (or 010) by virtue of it's size, won't fit where the original goes. So it's either cut the side panel about or relocate the unit .... hence the ali plate and a new home under the coils.

Steve .... turns out the net is positively jumping with bike forums using these units as upgrades - Triumph, Suzuki ... even dear old Honda!

Just a question... and please forgive me if it is a stupid one but my knowledge of electricity is very poor :-/
The 2007 Honda CBR1000RR, from which Stanleybobly took the FH008EE regulator, has a 350w generator while the capo mounts a 470w unit.
Could this mean that the FH008EE may be undersized for the capo?

Honda installed 350-watt AC generator on their bikes, our Capo's has 470 W generator.
the rectifier converts incoming AC in to DC (12V)
