Series Regulator Source SH775

[robertbarr]

That is an excellent price on the connector / lead set, even if we wind up cutting off the ends & soldering. A lot less than I paid just a few months ago.

We've found some on ebay that were reasonably priced (not like this, though!) that still required open-barrel crimps, which are OK as long as you have the tools. This set is ready-made. Thanks for the link.

Hi guys - quick intro:
posplayr referred me here to introduce the SH775 (we have exchanged a little correspondence over the years regarding Regulator Technology)
I've been long time advocate (one of early adopters) of the Shindengen MOSFET which I have always promoted as a reliability fix for high failure SCR Shunt Regulators - while recognizing does nothing for the stator reliability.
Generally has been the best solution from cost-effective perspective for those bikes/models which have high R/R failure rates but do not readily burn stators
However I do recognize the benefits of Series Regulation and waiting for suitable (read affordable!!) opportunity to get on board.
I recently picked up a Compufire 55402 for a great price and looking forward to doing some testing (although not much new to learn there after all the work posplayr & others here have done has done in that regard).

So enough on the background - just wished to offer my congrats & appreciation to those pioneering this recent application development (looks like the R/R itself has been around for a few years, but found new life in after-market thanks to efforts of various on this forum).
I have added this as a suggestion on my own forum thread & linked back to a couple of those threads on here. It is an excellent candidate for a couple of the Triumph models.
Excited to see that Shindengen has another couple of higher current Series models in development - we'll look forward to those making an appearance.

I did want to offer one tidbit in return however - Triumph has an OEM link lead that is only about $10 that connects to this form factor
- the Triumph Part Number is T2500676



It was introduced by Triumph as part of a retrofit kit to MOSFET R/R to plug n play into their std wiring harness (HUGE failure rate of SCR Shunt R/R on one particular model due to poor placement/cooling resulting in overheating and subsequent fail).

The price is incredibly attractive:
Even if the input/output connectors do not match up exactly with your application, it is going to be much more cost effective to replace those on the Triumph harness, than buying the Furukawas which are significantly more expensive!!
So worth considering - should be able to order from any local Triumph dealer or on-line
e.g. http://www.triumphmcparts.com/produc.../T2500676.html

Incidentally cheapest I have found currently for the SH775 is here $60 + ~$13 shipping

While researching, I came across this simulation of a 3 phase SCR Bridge Rectifier with varying firing angle - nice graphical display of how these things work.

SH-775 results seem to be confirmed it is a SERIES R/R and the R/R of choice for all 3 Phase PM charging systems which includes almost all GS charging system.

Just took a long look at the shindengen web site that niclpnut linked to and found all of my answers. I'm sold on the the series reg-rect. and have yet to install the FH008EB.

Just so you know FH008EB is a FET SHUNT R/R not a SERIES R/R

Just asking

I have only had my 83 gs11 for a short time, working out the bugs before riding season. This thread has been very interesting. I bought a used R-R for a 08 honda cbr 1000 to install on my bike. Is this unit a series type , or FET or are they the same? I still get around with a 1972 ford truck with contact points and a carburetor so all this hi-tech electronic stuff is confusing. any help or advise would be helpful.

So now I am grasping at straws.
Are we talking metal or the resin?

No matter my new unit works just fine and the heat at eh engine case is less during a touch.

[posplayr]

What I think I meant PP was that once a high heat had made a dis-colouration then no subsequent heat build up less than the highest achieved would produce any further dis-colouration.

Like a torch on metal and the pattern you get. You cannot change the pattern unless you add more heat...... Least not from what I have seen.

The problem with that theory is that the supposition is that the discoloration gets no worse than that shown. Not true. Again more background, I had just changed the ES stator and ran it 250 miles yielding the discoloration shown in the picture. The former ES stator had 5000+ miles and was burnt (i.e. much worse discoloration). There was no change to the FET R/R. So the heating effect in the pictures you see is only the initial discoloration. After changing to CF, the discoloration stopped.

[posplayr]

Or the heating discolouration had reached its fullest extent for the range of temps it was being exposed to?

I am a firm believer of the touch test. My cover is hot not searing hot to the touch. The cooler running stator would act as a heat sink yes?

That would appear as a totally off the wall supposition. I'm sure I stated before that after changing to the Series R/R this particular stator's coloration never changed again.

I have not the faintest idea if it runs cooler or hotter than before... No gauges to measure so I tend to ignore it!

What I can tell you is that the Kawasaki ones that get more oil to them do not give out as easily as the Suzuki ones....

Prices are rising????? I'm calling Bernanke and writing the media- they keep telling me all is well and don't worry, be happy!

...droll on my brother, droll on. Now please pardon me while I go buy things on credit to do my part in The War Against THEM!!!

But seriously, there was a 33% price spike overnight, it seemed alarming to me at the time anyway and I think my Visa is still crying softly to itself.

Anyways, let us know how it works out- I'd opt for the sh-775 if I needed a decent R/R right now. Did you actually test the R/R before you pronounced it dead? my shindengen survived my short circuited stator with no problems (I tortured it by running it deliberately) . and Thanks for posting,

I had determined that the R/R was dead last Fall but I'll be checking it again to verify. The charging system went down shortly before I was going to ride to Georgia so there was a lot of repacking and plan changing going on at the time. I'm swapping out the whole top end of the engine at the same time so it'll be a bit but I'll post back with some numbers once I'm done.

I'm running one of these & it works at least as well as the FH010 that I had on it before but I still have not seen any independent test as to it being a Series unit.

Heh... I'm not putting my foot in that battle. Tell me though, does your engine run cooler with it? Shindengen says it's Series as well as the parts listing so I'm just going to go with that unless someone comes up with better info.

Just as a heads-up in case anyone was on the fence about this: Prices are rising. It'd seen this 4012941 Polaris number around $60 at several sites but I hadn't pulled the trigger yet. Last night I went to order a couple and the price at motosport.com had jumped $20+ and had similar jumps at other sites. I ended up buying from Partzilla for $63ea but with pricy shipping.

Anyway, now may be the time if you were thinking about it.
