Title: Voltage Regulator
Post by: Fasttimez on Sep 24, 2018, 01:35:46 pm
There's a great thread on the Raider FB page from a guy who did a lot of digging & found an "upgrade" for our voltage regulator.  Our regulators put out a constant output regardless of the draw it sees.  This in turn leads to the stator whine & shortened stator life "that's the theory anyway, but a pretty solid theory".  The new regulator is a plug & play model, it's a "smart" regulator, as it only puts out what it sees the needed draw is calling for.  This in turn is easier on our stators, adding life to them, & cures a lot of the whine because it's only supplying what's needed.  A lot of guys have done the swap, & reported great results.  I just ordered a used one off EBay for $50 & gonna give it a try.  I have a very slight whine at idle, & in the first 2 gears only, gonna see if this fixes the issue. It seems we're the only ones in the entire industry using the "dumb" stators, as every other manufacturer, & other model Yamaha's use this one as well.  The number is SH775AA.....if you try this swap, buy a USED stator.  The aftermarket is flooded with new cheap knockoffs that are NOT the same quality.  These can be had used for $50 - $100 depending on where you find them.  They are used in everything from SeaDOO jet skis to Polaris Razors...... I'll report back when I do the swap.

It's supposed to be here by Tuesday, I'll pop it in & give it a whirl.  People claim it has fixed their stator whine issue.

That's the exact model I'm looking for. Unfortunately all my searches have netted only new units ($$$) or cheap knockoffs. Must be a Canada thing.
I'm also following this on FB

Don't search the part#, search SeaDoo GTS 130 voltage rectifier (maybe other models too, I don't know).
This is the guy I got one from - it shows the part# on the one pic.

I didn't really notice a whine - just thought it sounded like a good thing to have - working great.

Go on EBay & put in SeaDoo Voltage regulator (they seem to be the most plentiful), then filter your search by selecting only USED parts.  This will bring up the Factory OEM units only.  Then just scroll through until you find what you need.  Also Polaris used ones seem to plentiful, uses the same ones.

Same guy I bought mine from also, mine came off a 2014 SeaDoo Spark.

Not necessarily, others have reported it quieted down their stator whine.  Just didnt do anything for mine.  I've seen where others have changed the stator itself & it went away.

At the risk of starting an argument, good voltage regulators are only going to put out what they have to put out--design/spec-wise (sorta like wives/girl friends!!!).    :rotfl:  Some stabilize voltage better/faster than others under varying loads and how much went into their design/expense (i.e. zener diodes, SCR regulators, linear/switching/AVR/PWM types).  Perhaps the whining stators have a lot of load on them (pushing their design limits) like a dresser bike with lots of electrical goodies on them, for example.  Just sayin' ....  According to my Yammie tech book, the Raider Mitsubishi "magneto" is rated at 32A at 5000 RPM and the Shindengen rectifier/regulator is 50A max.  Adding heated riding gear will give it something more to chew on there!  My old Honda CB900 generator was only rated at about 350 watts.  I've gone through a lot of problem car alternators over the years and they usually have had bearing/armature/brush wear issues or the zeners just died from excessive heat, esp. GM crap.   :o   Anyway, I can't hear my own SCL stator making any noise over the beautiful sound of the 113 and Cobra pipes!  I have no extra electrical accessories installed at the moment.   :wheelie:

I'm just gonna put my old one back in, just figured I'd waste some money & try something new....LoL  Got a good used regulator for sale if anyone is looking, $40 shipped to your door  ;D

I'm the guy who first tried / suggested the R/R mod on the Facebook Raider group. Mine is running great and stator whine or not, you really should consider this mod. Here's why...

Reasons Raider and Stratoliner owners should consider upgrading their rectifier to a Shindengen SH775:

1) These 3rd generation “Series” Rectifiers are herald as stator savers.  (1st gen) Shunt and (2nd gen) Mosfet rectifiers pull 100% maximum voltage from the stator at all times. The unused / un-needed electricity is returned to the stator and grounded out which generates a considerable amount of heat.  "Series” rectifiers are intelligent, and pull “ONLY” what voltage they need from the stator moment to moment resulting in a much cooler running stator not under constant full strain (average 50-60% reduction in stator temps). The cooler the stator runs, the longer the windings and insulation will last.

2) The SH775 rectifier upgrade is a very simple plug and play upgrade to the Raider / Stratoliner. Even the most mechanically challenged owner can do this themselves in roughly 10 minutes with a allen wrench and basic socket set.

3) The SH775 is cheap upgrade. Used Shindengen SH775 rectifiers are commonly found on Ebay averaging anywhere from $35-60.

4) I have received feedback from a fellow Raider owner who suffers from the widely reported and dreaded "stator whine" that upgrading his OEM rectifier to the Shindengen SH775 completely eliminated the stator whine on his Raider. So it stands to reason other Raider owners who suffer from stator whine noise may too find an added benefit / incentive to upgrade to a  Shindengen SH775 rectifier.

5) The 3rd generation "Series" Shindengen SH775 has been used as a upgraded rectifier replacing older 1st generation "Shunt" and 2nd generation "Mosfet" units in countless motorcycles from vintage to new. While using the SH775 is a "new" idea for the Raider, it has been used extensively and is universally praised for most motorcycles going back many years. A google search of "Shindengen SH775 forums" will give you an exhaustive amount of feedback / discussion from other Motorcycle owners using the SH775 should you be so inclined to conduct your own independent research . The only motorcycles that use of the SH775 should be avoided is high revving sport bikes (crotch rockets). RPM's above 10k are problematic for the SH775. Our Raider and cruisers as a class don't even come close to 10k rpm, so no problem.

FAQ

1)  You want a USED Shindengen SH775 unit, not a new one! There are a lot of “new” no name Chinese clones that look almost identical to a Shindengen averaging around $50-65. Dont be fooled into buying one, they are NOT Series rectifiers (they are confirmed to be mosfet) and certainly not Shindengen units! If the Ebay ad does not have a picture of the used rectifier with the SH775AA / SH775BA lettering on it with the provided pictures I strongly suggest messaging the seller prior to buying to verify the unit for sale is indeed a Shindengen SH775. The Chinese knock offs have no numbers on them. If you incist on a new Shindengen SH775 expect to pay between $150-175.

2) Used Shindengen SH775 are rarely listed on Ebay by searching " Shindengen SH775 ". They are most commonly listed and found by searching for 4012941 (Polaris part number) and 710001103 (Seadoo / Can-Am Part Numbers).

3) Shindengen SH775AA or SH775BA are both fine. As best I can tell, the AA / BA designation is nothing more than a minor internal revision to the SH775 PCB.

4) The OEM Raider Shindengen FH012AA is a 50amp unit and the Shindengen SH775 is a 35amp. There should be no pause for concern. The Raider's stator is rated at 32 amps, so the extra 15 amps the OEM  FH012AA rectifier is capable of is lost on us by default.

5) The SH775 has built in over-voltage protection and will not damage the Raider's electrical system.

6) Shindengen makes a 50 amp "Series" rectifier (SH847). Fair warning, while the pin out and connectors are identical to the FH012AA and SH775 and it would plug in and work, the dimensions on the SH847 are larger and the mounting holes are different. They will not fit the Raider's factory rectifier mounting location! To install a SH847 have to likely cut and extend the factory harness cables and find another place to mount it that gets airflow but is not an eyesore. The SH847 is 3-4 times the cost ($160-200) and while it's 50 amp rated, our stators only put out a Max of 32 amp (SH775 is rated 35 amp). Given the added cost, extra work, and no discernible performance difference on the Raider I see no point to using the SH847. Stick with the SH775!

The current discussion /feedback regarding the SH775 on the Raider can be read in on the Facebook Yamaha Raider group.

Reviving an old thread, I've talked to a couple people who've done this mod and said they feel like their bike lost power, another said his lithium ion battery died because of improper charging caused by the new regulator.  Anyone have any experience with this ?
