stator dead

[ofstone]

 >:( :'( I think my stator just died.
I was keeping in mind about someone said yesterdaythat the stator side cover going over 100 degrees Celcius was verry bad. After i ride i measured the voltage again. and it was about 13,5 at 5000 rpm with lights on. Before i had 14,3 with lights on. I measured the stator, and gues what... one  coil shorted to ground. And just a day before i go on a holiday. I am afraid i cannot get a new stator and get in in the bike, before the holidays.

As i looked to the pictures of h2olawyer i saw mine was looking the same exept the big shorted pole. But it was not shiney black but  a bit granulated black. I should have known this and replace it at once.

It was a bit tricky to do some measurements, because all my wires are soldered together. I desoldered the stator wires. (stupidly after removal of the stator) and found out that there was nothing wrong there with the stator. Equal resistance betwen the coils. No severe burnt looking poles, and no shorts to ground.

I checked the R/R and it seemed that one of the white wires is shorting to ground. So i disconnected the big black wire from the R/R and i still had a shortage. Soo i removed all wires, and gues what, One of the white wires is shorting to the yellow wire coming out of the R/R. The diode bridge lookes fine and is working. But somehow an shortage has occures between those wires causing a short between those wires.
I soldered the yellow wire, because it was allready connected before i soldered the wires.
To me it looks that the yellow and brown wires are sensing wires to measure the voltage, without voltagedrops.
The yellow wire is somewhere in the harness connected to ground. And the brown wire is somewere connected to the system voltage behind the key-switch.

Strangly enough the wire is nowhere visible in the original OEM schematics.

I wonder, what the best thing is i can do. Can i still use the old RR? or is it not good anymore. What happens if i leave the yellow wire not connected?

Since the current should have been flowing thru the yellow wire, i checked the wire for burning or overheating since it is an AWG 22 wire (that wire gauge i used to lengthen the wires after the R/R was moved to footpeg) But i could not find problems. Luckily i have some resistors in series with the stator wires, so that maybee saved my stator, although it got really hot, at least 150 degrees celcius i suppose.

I hope the scrapheap has a good r/r but i need 5 hours to drive to it and back, and then mount evrything together, test, and then do all my packing for the small holiday ride, and hope everything goes well.

Ofstone, on out (U.S.) bikes, the yellow wire is not connected to anything, Electrex says it's "a special output-wire for switching the lights on & off"
What is it connected to on your bike?

For some reasons it is connected to another yellow wire, and that wire is somewere on the bike connected to ground, so when i replaced the connectors for soldered connections, i thought it was a sense wire for ground, just as the brown wire is for the +12V.
I think that is what damaged the R/R.

I hope the scrapheap man has an second hand one for my vision or another one that fits for the vision. And then i leave the yellow wire not connected.

It is posible that the OEM (shindingen) R/R still is working, but i do not trust it anymore. i do not now how it is connected to the regulator part in the bike.

I hope i have enough time to reassemble the bike an fix it before tomorrow.

[ofstone]

I am checking tehelectrex site to find a replacement one, in case the scrapheap does not have a regulator for a vision.
I gues every stator wich has the RR39 number is ok.
Why do some other bikes have the same stator, but another RR?  Has that something to do with mounting holes/position, or a higher power model? like the one from a xv535 virago RR48. Is that also good?

[ofstone]

I found on a local bike shop, an R/R sh541-12  From a honda VF750, and also used on a goldwing (type i do not know)
It has 3 stator wires, 2 green wires (both ground i suppose) 2 red/white wires (both 12 power) and one black wire (the sense wire, i should connect to the brown wire.

I really hope that this would fix it, so i can go to hoiliday tomorrow.

[ofstone]

Everything is  connected, and working fine, i now have 14,7 volts steady, and the stator is not getting so hot as before.
I only paid 35 euro for the RR.

Glad that worked out for you. How did you arrive at the color code to connect it? If I were just guessing, I would have run the black to ground and connected one of the green wires to the brown (sensing) wire.

green on Honda is always ground

Thanks Rick, good to know.

I am just back from my short holliday in luxembourg. (small but beautiful county stuck between belgiun germany and france) And have driven the bike for about 1000 problem free km's. Only had one problem, of a shorted lite bulb in the rear-left turnlight.
Luxembourg is a nice country to ride, because the nature and roads are wonderful there. Riding over mountains and things like that.(in holland everything is flat, so almast all roads are straight, with almost no bends. Fun to ride fast, but not to make some corners.)
It was verry crowded by motorcycles this weekend overthere.

I found out that the bike feeled not good, when i was riding up the mountain at high speeds in a sharp long corner. The bike was wobbling a bit. To me it lookes like it has something to do with the the mono-shock.
Also the temperature of the bike raised to 3/4 during riding up-mountain. And the stator cover still got hot enough to sissle water. I think i am going back to the desighboard to make a series regulator for the vision.

I was greath fun to stop on top of a mountain, and then other bikers come to me to ask what kind of bike it was, because the y had never seen a bike like that. They all thought it was bigger than 550cc, because the bike sounds like a big engine. The only believed it when they saw the 550cc markings on the outside of the cylinder. Also when riding thru villages with bars/terrasses with bikers, they all look when you open the throttle. and are looking for something like a ducatti, but then see a bike they do not now.

haha the big weekend was greath fun.

check out your fork steerer bearings.  if they are the stock ones and you have more than 5k kilometers they may be shot. i had to replace mine at very low milage.  they were making a craacking noise at times
this is a fruitful source and well known one for vision wobble.  probably not the rear shock or its mounts but anything can happen!

[Walt_M.]

It could be the rear shock if you have a high mileage(km) bike. If the damping isn't firm enough, the up and down motion at the rear could make the handling wander. It might not be a textbook wobble but the steering would not be sharp.
