Hi all,

I know this one has been done extensively and I've had a quick read through the old posts.

I just wanted to post up my particular symptoms before I order a new RR51 in case it's anything else and I'm being dumb!

Firstly, I've attached a picture of my current R/R as I'm not sure if it is the early or late type. (I know it's undone with the earth strap off, I was re-fitting it after checking all the wiring when I took the picture )

Basically the bike runs fun with the lights off and I can blat round as much as I want.

On the way home from the cafe on Wednesday it was getting dark so I switched the lights on and it started playing up, misfiring etc. within a mile or so and stalled shortly after. I managed to get it home after a bump start but it was running like a bag of nails (much to my wifes amusement when I got home )

I've checked all the wiring and it's all fine, nothing melted, shorted or anything but the R/R does run very hot even at idle.

I decided to re-locate it under the seat unit to get it away from the exhaust and it still runs hot even at idle. It also does not appear to be pumping much more than 0.5v into the battery @ 3k RPM but the battery is fully charged and very healthy so I'm not sure if it should. I can't seem to get it over 13v though so I don't think it is charging.

Took it out again yesterday and everything was fine, she is a little honey, and on my way back, about a mile from home, I decide to turn my lights on after maybe 60-70 miles total riding and within 100 yards she is popping loudly on overrun. About 200 yards after that, even though I switched the lights off almost immediately, she starts running rough and I barely get it home - stalled about 50 yards from my door

To my mind it is either battery, R/R or generator/stator.

The battery appears to be fine, charges well and holds 12.4 volts no problem.

I can't see any obvious problem with the generator/stator so it has to be the R/R?

Sorry for the long post, I just want a bit or reassurance before I order the new one later today.

Many thanks!

Phil
