The industry uses 14 volts DC as the standard for alternator output. So Ohm says 26.7 amps. Which is about right for an oil cooled permenant magnet AC generator. That's the same type my ST1100 used in 1994. Everyone toasted those eventually and upgraded to the 1996 aircooled unit that was rated at 560 watts.

I had the EXACT same problem last year with my 2004 950s and it was the Voltage Regulator. Headlight would turn off when I accelerated, then once after a short ride around town an insane amount of heat was emanating from the engine area, despite the thermostat marking 4 bars only, there was the high pitched alarm (overheating sensor alarm, I think), and my bike smelled mildly of burning potato salad.

Could not figure it out. Things eventually went back to normal.

Then I set off for a 4.5 week tour with my girlfriend to Botswana and back (from Arusha, Tanzania, where I live) and on day 1 the bike backfired and shut off from fuel starvation on the road. Same symptoms - whine, smell, but this time it didn't start back up.

Devastated, I put it on a truck, took it back and we realized it was the voltage regulator. The battery was cooked but miraculously, the rest of the electronics were not fried. The fuel pump had shut down because of the voltage overload so that is why the bike died on the road. We fitted on a voltage regulator and battery from a Yamaha 660R (same bolt pattern), took a spare dry cell battery and cables in case we needed to boost the little Yamaha battery in the mornings, and set off.

9,000 kilometers, 5 weeks, and 7 countries later, we returned to Arusha on that same Yamaha voltage regulator and battery. Never had to boost it with the dry cell.

Have an OEM voltage regulator on the way and have the right battery in there now. We'll see how they work!

Here's a PDF link for troubleshooting voltage regulator guts:

Bad VR's

there are several components in the VR's that are getting incredibly hot for their small size, in a waterproof resin jacket in the aluminum heat sink.

VR800 owners all move their VR's into a better airstream

Try Rick's Electrics (NOT Ricky Stator). He makes the stuff himself and knows more about this than anyone I've ever talked to. If he doesn't have one that will work & if there's is a market, he'll make some or rewind yours. He knows how to balance the windings/flywheel & VR to suit each application, and talk at length on the phone, something the guys importing "upgraded" stators/VRs from China can't do.

I have an ElectroSport 400 watt stator in my KLR650 running a stock VR moved into an airflow pocket under my sidecover- much better cooling then under the seat where Kawasaki put it. I bought a higher rated VR but never have put it in, and those are dual PIAA Intense White H4's running on that bike- it always starts, bulbs don't blow. both bulbs usually on highbeam... and I like to ride in tight woods at night, not the day & the lower RPMs & battery recovery is good- if you're crawling and the fan comes on the battery starts making up the difference. I don't have to add water to the cells either. Balance.

airflow... cooling... make your own extension lines if need be

Update

Replaced the VR and Battery. Did a full service, valve adjust and such while I had the tank off.. Bike wont start, looks like the fuel pump isn;t working. Opened the fuel pump cover up and the whole area with the points are covered in a deep layer of black soot. New fuel pump fixes it.

Besides the battery, fuel pump and light bulbs I wonder what else can be firied or had it's life sortened on this bike??? Not feeling really confident that I want to take this thing out alone in the desert on a ride again>

Hey CP what do you think about this?
Did a little digging here..

Found this..
Rated at 40 amps
http://www.regulatorrectifier.com/catalog/Universal-Three-Phase-Regulator-Rectifier-for-40-Amp-Stator

rated for 50 amps?

Haven't heard from anyone using their stuff, yet. The 50 amp Speed Triple unit has possibilities at first glance, but will need new connectors to match the 9xx, of course. Have to do some research and see if we can find some data.

A link to my battery singing in a SS bowl on the driveway, I too was lucky to get it out of the bike without incident.

i had the same problem on my Ukrainian Tour, battery was singing,
I think problem was about SE construcion, so, my new VR (from 950 ADV), I instaled, on the lest side of airbox... that is good place for this.

I know on a drz400 I had, the fix was to put an yamaha R1 VR on and it was golden. I wonder what other bikes VR's would work? How much is the stock one from ktm?

Crap! My brand new AGM battery went into overheat mode and ended up wherever dead batteries go after they die. With the stench of the sulfur, I thought it was the rapture (it WAS May 21, after all).
So I got stuck at Lake Powell for one night before a buddy came to rescue me with truck and trailer -- been broke down in worse places.
This '08 SE is on it's second VR and if it turns out to be that it is at fault (after all, it may be a faulty battery) I will seriously consider relocating it as well.

ex 1- that is a good place for it. I have my HID ballast or some f'n thing in there right now. Think I'll be searching for a new location.

Colo Uli- sorry I didn't find my phone sooner! Sorry man, you've suffered some shit with that fuckin bike. Here's to smooth riding!:

It's all good, brother. Don't sweat it.
Hey, pretty soon I'll have replaced everything on it twice (minus the motor) and so it should be nicely worn in and SMOOOOTH.

I don't think I can mount it where ex1 put his (hers?) 'cause the Safari tank covers all the area. Perhaps on the inside of the bash plate where the 950 ADV bikes have them (if memory serves)?

I had also the singing problem --> changed the regulator + battery since both were dead...

ex1 has a good place for regulator. I managed to bend some aluminium sheet into heat protection (hope so..)

All right KKO! Nice going.

I'll explore that heat shield design and may copy you. Do I owe you royalties then? If yes, I only pay in beer, and you have to come to Colorado to get it. But I do pay.

Welcome to ADVrider! For that piece of advise I shall dispense with the customary requirement for you to show us nude pictures of your sister.
