Hi All :wave
My 11 year old 955 has a duff battery. It was only put on just under two years ago, and the bike has done about 4,500 miles with it on :icon_frown:
Do you think it could be caused by the dreaded rectifier issue ?? I've read a few threads about rectifiers over the years, but never worried about mine, as it's always seemed ok.
Would wiring in a simple volt gauge, and checking the voltage when riding, be sufficient to keep an eye on things ??
Could just be a dead battery, if the bike has sat for long periods they can just die, if the battery is ok it is possibly the Regrec or stator. First test the battery with a voltmeter and the bike off, then test with the bike running to see whether its a battery issue or charging related. Plenty on the site about what the readings should be but as a start point a charged battery should be around 12.7v with bike off and you want to see somewhere north of 13v with it running.
Once you have sorted the problem, a wired in voltmeter is a useful addition to keep an eye on things.
These bikes have a history of iffy charging electrics but i've Found things have become more complicated in recent years as battery prices have dropped and so has the quality and i've Had a couple die a death and i've Now started changing batteries at the 2 year mark the only one one that is out of sync is the lithium on my XT which is over 4 years old and as good as ever.
Battery prices dropped ?? Not as far as my jaw when I had to fork out £75 for another Yuasa (heavy duty one this time) :icon_cry:
I did the usual checks on the stator, and that seems ok. I've got a cheap voltmeter on order, so will (try to) wire it in with a relay so it comes on with the ignition.
Will probably get a new R/R, but I'm still not quite sure which one I should be going for, and how to wire it in properly and safely. DEcosse on the other forum recommended a SH847, so looking to source one of those in the U.K.
I've had a good read of the Sasquatch mod thread, so will probably go down that route.
If you do change the RegRec, the simplest way to go is a Shindengen RegRec and the triumph upgrade connector (this makes it plug and play!). Having tried the mod and a number of different RegRec's over the years and miles, this has been by far the most reliable set up for me.
75 quid for a battery :icon_eek:
After blip with my Reg/Rec Electrex sent me a new RR881 which has gone into my spares box as I had an original reg/rec that I bought off eBay must 10 years that is currently doing 14.7v
I'll be going with the 847, but I'm rubbish with electrics. Soooo not looking forward to wiring it all in. There's the horror stories of connector blocks melting, fuse holders not being big enough, wires melting. If anyone can can do a complete write up, that would be great :icon_wink:
The RR881 connects into the wiring same as the Sasquatch mod in other words it connects to the alternator and instead of connecting into the loom you have two extra wires to go onto the battery,they even supply the male and female connectors to the alternator,biggest hassle course is pulling the battery and tank out off to fit it.
Think i've Put in another post a while back when the electrical system is working exactly as it should it's amazing how much better the bike runs at the risk of pointing out the obvious :icon_biggrin:
If you go the SH847 Route, (by the way, he SH847 is a Shindengen RegRec, the latest version I think), the easiest way to wire it is the Triumph Connector Part No : T2500676 see below
https://www.fowlersparts.co.uk/parts/view/T2500676 (https://www.fowlersparts.co.uk/parts/view/T2500676)
This makes the RegRec plug and play so you don't need to mess around with wiring.
Thanks for the info chaps, just need to source a genuine 847 now in the U.K. There's a couple on Fleebay in Germany, but not sure if they're the real deal ?? I've heard there are a good few fakes out there ??
https://www.ebay.co.uk/itm/Voltage-Regulator-Langsregler-SH847AA-Incl-Adapter-Connector/183354326236?epid=4007161931&hash=item2ab0c4fcdc:g:O7kAAOSwj~dZ38l7
Hard to tell whats real and whats fake on ebay. Certainly priced as a genuine part. Think I brought my RegRec from this guy in the US a few years back and its still working fine, not sure how many miles but I think I moved it from one bike to another so it could be over 100k!

Hi :icon_smile:,
With a new volt gauge wired in, here are the voltages I'm getting. Please could anyone let me know whether it's worth buying a new rectifier, or are the voltages sufficient to keep old Tigger going ?? I've included cold (C) and hot (H) engine voltages:
Ignition switched on only, engine off: 12.1
Tickover: C13.2 H12.5
2,000 revs: C12.9 H13.6
3,000 revs: C12.6 H13.3
4,000 revs: C12.6 H13.1
5,000 revs: C12.7 H13.0
6,000 revs: C12.7 H13.0

Where is your volt gauge wired to? If its direct to battery the readings are low but if youve taken the feed from somewhere else they may be ok. Have you tried just unplugging the reg/rec connectors, cleaning the contacts etc, I got a whole volt back by doing that once.
The volt gauge is wired direct to the battery via a relay that comes on with the ignition. All voltages double checked with my multimeter as being correct. Every connection on the bike was cleaned and had dielectric grease put on them when I had trouble with the bike not starting a couple of years ago.
I suppose I'm just wanting to know at what voltage is the rectifier not providing enough voltage to power the bike and keep the battery charged ?? I've read that the rectifier should be providing about 14 volts to keep things right ??
I've seen worse but your readings are low your a volt short.
Thanks Chris, that was what I was thinking :icon_frown:

My thoughts too
Trying to kill two birds with one stone with the other post about wiring and how the bike runs,i've had a complicated run with my 955 since last year,fitting a lithium with a Reg/Rec that didn't like it and both the reg/rec and the battery were kaput,then a new battery and reg/rec on but the reg/rec was wrong and fried itself and was sent a replacement but in the mean time fitted an old original re/rec
And there's no doubt when the electrics are as they should be the bike is a whole lot happier by some margin certainly when it comes to the running of the engine the voltage only has to be a tad down you can notice it.

Bloody hell, and I thought I had problems !! :icon_sad:
One of the great joys of multibike ownership just ride something else while i'm Sorting it and while mine is some distance from a stock 955 it's going better than it's ever done god knows how it's never gone bang :icon_eek:
Had time to give my stator a good check over yesterday.
Ground test ok.
Resistance test - .3ohms on all three connections.
AC voltage output test on all three connections:
tickover: 25V
2,000revs: 32V
3,000revs: 46V
4,000revs: 61V
5,000revs: 74V
I've decided the stator is ok, and have ordered a SH847 to see if I can find the extra volt and a half I need. Looking at the Triumph plug 'n play lead (T2500676) in the UK, it's quite expensive compared to the States ($10). It's looking like £20 plus postage.
Anyone know where I can find it cheaper in the UK ??
Okayyy....quick update....
I got my new SH847 on the bike today, and wired it through the Triumph link lead (T2500676).
On start up, the bike showed a steady 13.8V from tickover right through the rev range. However, as the engine got up to operating temp, the voltage dropped to 12.9V on tickover ?? With a few revs on though, it went back up to 13.8V and stayed there throughout the rev range ??
So I "think" I'm happy with the way things are. I must admit, I was expecting 14V plus. I got some spare connectors with the rectifier so might try wiring them directly to the battery to see if that makes the difference ??
As a side note for anyone thinking of getting the SH847. It fits directly in the same bolt holes as the original rectifier, no need to make brackets, or drill the frame.
Quick experiment to test the theory.....
I disconnected the output connector from the rectifier and wired a couple of leads directly from it to the battery. I got 14.2 volts on tickover, and 14.1 volts throughout the rest of the rev range.
So my next question.......is it worth doing the Sasquatch mod properly just to gain .4V ?? :icon_scratch:
In short no

Hmmm ?? Too late, I've got some 10AWG wire on order for the mod :icon_wink:. Just want to see if it makes a difference. It's relatively inexpensive to do the mod, so worth a try to see if I can get in the magical 14V's :icon_wink:
Just trying to source a suitable maxi fuse holder with 10AWG wire, but struggling in the UK. I can get one, but it will have to come from China, and to be honest, I'm not a fan of buying from there as I don't trust the quality.
If its working and you are already getting 14v I wouldn't mess with it. Lots of people have been let down my the mod (myself included) for various reasons but mostly poor quality or inadequate maxi fuse holders or connections.
The Triumph connector you have used is their upgraded wiring and is much better than the original RegRec connectors. As long as you keep an eye on the connector (dieletric grease now and then) to the stator and make sure there is no corrosion it should be reliable.
That said, if you want to give the mod a go, do it as its easily reversible but make sure everything you use is up to the job and that your soldering skills are good or you risk saying goodbye to an expensive RegReg or stator.
Just for the record this is what Electrex sent me complete with stock Sasq mod.

Nice, good to see a supplier listening to their customers and actually trying to solve problems rather than just copying the OEM equipment.

Thanks the advice, but everything's ordered, just waiting delivery.

Yep, agreed, good to see suppliers listening to what we actually need :icon_wink:
Quick update:
I finally got round to doing the "Sasquatch Fix" with the rectifier wired directly to the battery. I used 10AWG wire and a 30volt maxi fuse and holder.
So at the start of all this without any modifications I was getting 12.5V on tickover, and about 13V throughout the rev range.
Then with a new SH847 rectifier on the bike I was getting 12.9V on tickover, and about 13.8V throughout the rev range.
And with the SH847 and "Sasquatch Fix" I am getting 13.1V on tickover, and a constant 14.3V throughout the rev range.
So an expensive way to gain 1.3 volts, but hopefully worth it :icon_wink:
A big thanks to everyone who helped out - Cheers :icon_salut:
