950 se voltage rectifier/regulator

My friend recently had a voltage rectifier/regulator go bad on his 950 SE. It also took the battery with it. He has since moved the unit away from the rear cylinder exhaust pipe so it doesn't succomb to heat of the pipe. How many of you SE owners have experienced this? I have 20K miles on mine, and worry about a failure out in the middle of nowhere. Any recommendations would be appreciated.

Thanks - gmtcm

Not me, but MANY others. 20k seems to be alot, that is where I'm at as well. Move it now, an cross your fingers?

You could move the regulator, switch it for a new one and keep the old as a spare. At least that way you don't cook a battery.

My VRR went at 3950km's. It took the battery with it.

I bought a Rick's Motorsports VRR and a new battery, and so far with ~2100km on them, it's working.

I swapped my good working one proactively at 60k, I'll get around to moving the new unit one of these days.

What happens is there is no early warning that it has taken out the battery, until the bike quits. By then it's too late. I guess I could install a voltmeter on the dash, but would probably never watch it and it would still go out.

My regulator went at 47000km. Surprisingly I still have working original battery, 5 years old. New regulator is relocated to left side of frame, I also installed voltmeter.

You may hear the battery whistling after you turn off the ignition. That is the sound of gas escaping because it is boiling up inside. Catch it early enough and the battery will survive.

My VRR went at 7000 miles and also took the battery with it. I replaced it with a Rick's Motorsports VRR . I had a strong sulfur smell coming from the battey as it was venting from the seems.

I didn't think there was much room on the left side of the frame to re-locate the VRR? Could you send me a photo of yours>

Thanks - gmtcm

Did Rick as well, 17k on the original RR & NO issues, just a precautionary measure. I kept the original mounting position as well. I figured since the original never failed from excessive heat, why on earth would the mosfet RR fail, just jinxed myself

RIDE ON!

Heya gmtcm

Ours didn't fizz out but we proactively relocated it away from the oven.

There is plenty of wire to bring it around to the left hand side, see toward th back of the tank and yoiu can use the same mounting plate as well.

Is the MOSFET Reg/Rec also sensitive to heat? Or could a MOSFET be left in the original location?
