I went for a ride this Sunday on some NH backroads. Erik Buell Racing ECM, heated jacket, high beams after it got dark and no problems. I never saw anything below 12.7 volts and it would go to 14v when I came to a stop. I have an LED wired into the system to tell me when all three legs of the stator are working. Whenever I come to a light I put it in neutral and let the clutch out. The third leg would always come on when this is done. It will sit at 14v at idle even with the electric jacket keeping me toasty warm. The air temp never went above 50 and the CT was usually around 165. Also, I've never had the battery light come on except for a quick flicker right after the bike starts.
Maybe I'm just lucky!
Oh, one other thing. I'm running the FH012 regulator.

I must be lucky then too, yours is similar to my experience as of late with the heated goodies. |

Wow! You guys see 14V at idle?? I usually don't see >13.7 even when moving full bore. At idle, high beam on or not, I see ~12.3 ... high beam on and I slowly droop to 12.0 where it sticks. It's just strange that very similar bikes act differently. If I was even getting 13 VDC at idle I'd be ecstatic.
PS, what's the "quote" tags for our board? |

Jeep - I think it's really helpful to know what is going on with the stator. If you put an LED across the +12 and switched ground that controls the stator relay, you'll be able to tell when all three legs are in use on the stator. If you're only seeing 13v with all three legs of the stator being used, you've got trouble with either the stator or the regulator. If only two legs are always energized then maybe the relay is bad or maybe you have a bad connection somewhere. On my bike, all three legs are in use whenever I start the bike.
Froggy - Are you still using the stock relay? |

its \quote, basically the same as any of the color tags but with the word quote. Click Help at the bottom for more details and more tags.

09 CR with Erik Buell Racing Race ECM, 11k miles, harness put in at 6k, stator failed/replaced 7k. I don't see 14v idle once its fully warmed up and the fans and everything are kicked on, but its always been in the 13's then, so I never thought twice about it. While I haven't done the LED mod yet, I am certain my relay is working.
I have been using a battery tender as of late, just due to the shorter trips and heated gear.

Blk09r - Whose ECM are you using? |

Re: External grounding of VR, I measured the case here. Anony speaks the truth - it's not grounded to any of its wires. |

Blk09r - Do you use a battery tender?
Sparky - I tried the ground wire using the stock ECM. First impressions were positive.
When I put the Erik Buell Racing ECM back in the voltage issues returned.
I am waiting for an Erik Buell Racing reply to an email on this.
I have a Barker tune with my Erik Buell Racing ECM.
I won't get the muffler until Erik Buell Racing shows that it can keep my bike alive on the street with their ECM. |

Great info sparky! Thanks for actually testing! To be doubly sure, you could always fire up the bike and put a meter between case and bike ground, with the meter set up to measure current (both AC and DC). If current ain't flowing, then current ain't flowing... |

This is interesting because my first stator failed exactly 15 minutes after the Erik Buell Racing ecm swap.
I now have a new stator and just put the Erik Buell Racing ecm back in- I'm nervous.

are these voltage issues happening to your 08's or just the 09-10's. Ive got the RT-3 coming next month and planning on running the Erik Buell Racing race ecm, but i really hate to jinx the bike because so far i havent had any of the major issues. |

Danny - Negative on the battery tender. |

Someone let me know if I'm wrong, but I can't see any effect the ECU has on charging except for when it controls the third leg of the stator. I believe I read a while back that Erik Buell Racing uses the same code as the stock ECU to control the third leg. I can see where they might have the threshold set a little higher for the battery light to come on, but otherwise the regulator should be controlling charging voltage.
Am I missing something? |

Blk09r - That could very well be the difference, the part I don't like. |

Blk09r - I think you're right. Also, I think the Erik Buell Racing ECM runs the fans more so that will probably contribute to lower voltages. I don't have any problems on my 08, running the Erik Buell Racing ECM. I know the problems seem to be with the 09/10 models but I'm pretty sure the tune is the same so I don't think the race ECM is causing the problem. |
