Bad Voltage Regulator ...OR?

O.K. looks like I posted my question in wrong spot, so here goes again. (sorry to repeat) Yes I know this is an old thread.
Have done some research on series vs shunt advantages and disadvantages of each.
Wanted to hear results from those who made the change, how did it work out long term?
Thanks

I installed the series regulator on my Touring and have had no issues, 2009 R3 touring. It seems to run cooler and charges at lower RPM. One of the members BeDifferent made a bracket kit for the Touring that worked very well. May no longer be available, but a good pattern.

Old but valid thread as these bikes get older. Wear like this will start to show. Have two 05's. One i don't ride, its just parked in shed and completely stock. The other is well used. It has a Series RR off a Suzuki fitted. Larger and relocated under side cover. Only issue over years was plug came out (my fault) after servive work picked this up before battery went flat on aftermarket gauges thatxare fitted. To my mind shorting the alternator coils just creates waste heat thats never a good thing in an engine. The shunt RR was probably used as it was smaller and cheaper. Remember its a world of disposable objects these days. We're not supposed to be riding these old ones but lusting after the new latest model and ditching the old. As long as the parts last the warranty the designer has done their job. My brains not wired like that though.

Yep, never looked back after the Suzuki part upgrade and with the simple cable tie mount under 2010 Roadster sidecover I posted years ago and much relief that it was my shunt regulator and not the coil that was fried.

Do you have a link to that post?
So with the stock unit reducing the amps required for the bike such as switching to led lights actually will cause the stock unit to need to dissipate more heat as the alternator output is fixed. The only advantage I can see for a shunt regulator in our case is that the are reported to tolerate a wider range of input voltages.
Thanks all for the responses, I will order the Suzuki part today!

Please note, anyone wanting to do this must be willing to remove the evaporative capture canister.

Arrived and fitted the series SH847 AA today - as advised earlier much bigger than stock and no way I could use the same position or mounts. In the end I wrapped and fixed some felt backed rubber around the rear frame tube and zip tied it in place behind the side cover with the much taller fins faced in where they will hopefully get some air coming past the prop shaft drive.

Will this suffice or do I risk cooking the other electrics? Where did others mount theirs?
Happy to say that voltage measured at my accesory plug is a happy 14.3 volts with the engine running and headlights on etc. Voltage with engine off 13 volts.

It certainly would not fit that way on my Roadster and I think Joesmoe (Paul) found the same on his Tourer. On my Roadster it will not physically fit in that space and engage either bolt thread and as Paul noted in Bad Voltage Regulator ...OR? the extra depth of the finning also means you would risk (or could even not avoid) the prop drive shaft hitting it with suspension movement.

Mine which I got 2nd hand with some mods done already, does not have the evaporative emissions canister which may not have been fitted on Australian spec models. I know we did not get cats in the exhaust collector tube of the '06 Sprint ST 1050 with underseat muffler can like US and Euro models did.

This is the mount I used, stock harness no add on.

Sounds like a plan, I'll look into it as soon as the part arrives.

Thanks all

The use of series to replace shunt type RR is widespread across all models and brands now.

The earlier SH775 version has apparently a lower rev range limit which would probably not bother the Rocket but the 35Amp limit is less than the SH847 50 amp that came with the SUZUKI V-STROM DL 1000

Since I saw this thread pop up, just thought I would pass along that I personally have had issues with the SH775 regulating at high RPM. It was on my CX500, not the 950, but shouldn't make a difference. The regulator effectively stops regulating around 8700 rpm and the battery voltage instantly shoots up. I saw ~19V out of the corner of my eye ripping down an on ramp is the only way I caught it. SH847 is in the mail...

Battery condition is extremely important. No voltage regulator can work correctly with a bad or weak battery. Always fully charge your battery before performing any charging system tests or replacing parts. If there is any doubt, have the battery load tested or replaced.

• Replace any burned or corroded connectors on stator and regulator rectifier
• Check and repair any melted wiring
• Use hi-temp dielectric grease on all connectors

DETAILS
BENEFITS OF SERIES VOLTAGE REGULATORS
SERIES regulators run much cooler than the Shunt and MOSFET voltage regulator rectifier and way much cooler than OEM parts.

Power only flows through the electrical components when the battery is charging.

Allows the stator to have lower current flowing when not used, extending its lifetime.

The regulator is easier to mount because it is smaller than the OEM one.
ABOUT THE SERIES VOLTAGE REGULATION TECHNOLOGY
RMSTATOR’s new SERIES voltage regulator brings better reliability and charging system performance. A SERIES regulator is a significant upgrade over typical shunt type voltage regulators.
A shunt regulator controls battery voltage by grounding the stator coils to dissipate current as heat, rather than sending it on to the battery. SERIES regulators control battery voltage by intermittently disconnecting stator coils from the regulator electronics, limiting current flow through the unit and on to the battery completely.
This results in lower regulator and stator temperatures, more accurate voltage regulation, and increased reliability of your charging system components.
INSTALL LIKE A PRO
We include the opposite connector (main harness side) as we know these are often melted / corroded / defective. Defective connectors are a major cause for repetitive electrical issues.


Advantage of SH775 is that as it is slightly smaller, it may fit in the stock mount area.
I think this post is from AdventureRider but I was struck by the cool off-road Honda CX500 V twin. great little motors.

This is another Oz distributor of similar SH847 type.
