Is connecting a carbon pile load tester (http://www.amazon.com/Schumacher-BT-...ews/B000AMBOI0) across the battery terminals while the bike is running a sane way of testing the capacity of the stator? Or is that just looking for trouble?

Our batteries are rated at something like 220 Cold Cranking amps, but obviously can't sustain that for very long .... IMHO, the 100A tester would be ok for a quick test of the battery's reserve capacity ...
If you wanted to test R/R & stator I think I would use one of the more expensive testers that allows the load to be adjusted down to match our charging system max. output (~30A) would be better .....

Ok ... I'll have to wait till tomorrow evening to post the pictures ... I'm a tad outta control...
but I got the scope measurements done today, and the Cycle Electrics unit I got from Jack (a hellova guy I might add) here:

http://roadstercycle.com/Roadstercyc...Regulators.htm

is actually quieter (less electrical noise) than the OEM unit.

In addition, while the OEM R/R was too hot to touch after 10 minutes or so of testing the Roadster unit was barely above room temperature at the end of our testing ... I'm really quite impressed.



My EE buddy is not surprised by the results, being the hyper-brilliant EE that he is, he pretty much expected it would turn out as it did...

I still have to make an adapter bracket to get the thing permanently bolted to the bike and then will do some ABS testing (at various levels of battery state-of-charge as Joel suggested) ... but based on the OScope traces we reviewed I am pretty sure there will not be any issues.

May I suggest, you start a new thread, and post it all up, as this might be the ticket. I am ready to try one, I think.

Sounds promising JR, may make a few people over at F650.com rather happy as the single instrument panel is a little prone to electrical noise and we have not really identified all the sources, perhaps the VR is one

new thread started with oscilloscope readings...

Someone suggested, and I agree, that it would be a good idea to start a new thread specifically for the R/R series to shunt comparison....

So ... here it is ...

Had a weird issue today. Starting riding to work at 2 pm and it's hot mid 80s' I have a Sparkbright voltage reading LED. Been working perfect. I stop in traffic for a bit and get amber 12.45V reading. I accelerate away and normally this would turn green for charging voltage. Its stays amber. Go a little further more traffic stopped. Slow red flashing indicating 12.25 V. I start moving and back to amber the rest of the way to work. Like I said it was hot, close to 90.

Fast forward, I leave at 11PM. Temp in high 60's. Bike fires up fine and has no voltage issues, stays green the whole ride home.

Now my question is this something that would be R/R issue. It started while it was hot so thinking an overheat. Or could this be something else. Looking for a place to start. Thanks

Could be a lot of things, including overheating electronics. They do act strangely when they get too hot! Kind of like me.
Electrosport (and others) specifically state not to mount it where it is shielded from the cool air flow. Probably for a reason.
As for the failure modes, hard to predict but I have seen FETs and other semiconducter devices fail open and shorted, which causes the opposite result in each case.

Maybe watching the voltage too closely is like watching the stock price every minute - leads to rapid swings in stress levels.


Hope it doesn't act up again. Good luck!

IIRC imintman had a temperature related failure of a OEM R/R ....
The dead part is in my garage having been relieved of it's harness connectors...

We rode our 2007 F650GS machines (singles) to Sedalia from Florida last summer. Plenty of heat for sure. No problems until this spring when the VRR on my wife’s bike began to fail. It was intermittent in the beginning but got worse. Finally it would zoom to nearly 18 volts upon warm up. I replaced it with a new OEM unit last month.

I have an '09 with about 48,000 miles on it. I have had a voltage indicator on it almost since I've had it. The indicator has always worked fine. Yesterday I went riding and about 80 miles out the voltage went from 13.7 to 11.8 so I turned around and made my way the 60 miles back to the highway with it indicating between 11.8 and 11.5. When I got back to the highway I opened it up in 4th, maybe 7500 rpm and it started showing 13.7 again. I have a ce series regulator to put on it but I haven't gotten it done yet but if the stator was burnt it wouldn't go in and out, would it? I suppose I will get another stator just in case but this seems weird. The temp was in the mid 80's so I don't think it was heat related
