Zoolander - if it was doing the same without the harness (and I recall you saying it was) then it's not going to be the pin or the relay oranything else associated witht he harness and the dealer should know that.
He's also talking out of his backside if he says it's "normal" as it certainly isn't.
Best bet is to recheck the ACV from the stator when the bike is hot, just in case there's a short in there that's only apparent when hot..
I'm sure you remember how to do it LOL... Get the bike up to the point where the DCV is dropping at idle, shut the bike off, disconnect the plug, start the bike up and measure the ACV across the 3 pairs.
Whatever you do DO NOT reconnect the plug when the motor is running, the stator REALLY doesn't like that...
Your dealer sounds awful - I feel for you... |

Apparently, a Grand Imperial Wizard (District Buell rep) look at the bike herself and deemed it "normal for Buells". I should get that in writing and notarized.
I rode it for about 30 miles, but this time I didn't have the screen showing the voltage. It didn't break down on me and I never peeked at the readings. Ignorance is bliss, I guess. I guess also that it's fixed.
It's tough dealing with these issues when I don't get a chance to ride all that often anyway. I just want to be able to get on and go and not worry! Anybody want to buy one for cheap? lol |

with the FH0012A regulator and the harness installed on mine it always stays between 13.8 and 14.2V even when outside temps are over 100 degrees, both fans are running, and i'm stopped at a light. The only time it hasn't was a couple days ago when it started only going up to a max of 12.8v and sometimes it would drop down into the high 11's. Ended up being the harness relay. Even though it tested out ok and was clicking on engagement the heat under the seat had damaged the cheap relay HD was using and it wasn't actually engaging. Replaced it and it was right back to staying at 14v. Oh and when the relay dis-engages it isn't just cutting off one leg of the stator it is effectively removing two phases, switching the system from three phase to single phase. |

What makes you think it removes 2 phases? Is yours wired differently than what's specified in the service bulletin or is this your opinion? |

you must have three wires or lines if you are looking at your standard generator for three phases... two wires makes one phase. wires are A, B, C three phases are AB, BC, AC... if you only have wires A and B then you only have phase AB. |

The relay only interrupts one wire of one phase, I believe. Let's say it disconnects A from AB. That leaves BC and AC untouched. How is that interrupting two phases? |

if you disconnect A then how can you have AC? You have to have a minimum of three wires in order to have a three phase output. Also with three phases at 50VAC you only have 25VAC at each line, this is how in a house you can easily run 220vac. Normal outlet is one 120vac line, one neutral, and one ground. To get 220vac you simply replace neutral with another 120vac line. Two 120VAC lines makes a single 220vac outlet(Basically). If i'm wrong here someone please chime in and correct me, i'm not an electrician but I just got back from Afghanistan where I did have to spend a lot of time wiring generators, AC units and different power outlets from a generator where some stuff was 110 and some were 220 but the generator only put out 208Vac 3-phase. |

FYI, ref http://www.electrosport.com/technical-resources/te chnical-articles/how-motorcycle-charging-system-wo rks
One thing to realize is that the 3 phases are connected internally as shown in this diagram assuming this is representative of 1125s:  .
Therefore two wires, say B & C will realize the output of 2 phases of AC current even though wire A is disconnected by the relay. Do you agree? |

They are connected on the inside but the wire being disconnected on the output means you get nothing from it. This system doesn't have a neutral or ground connection to the generator so the only way to complete a circuit is line to line. One complete circuit is a phase. i.e. A-B, B-C, A-C. Also they are not all firing at the same time, only 1 phase is producing power at a time, by removing one line you are removing one part of two complete circuits thereby removing two phases. Therefore when the relay disengages the generator is only realizing 1/3 of the total power load. |

My bike's (1125CR) voltage was all over the place. it would charge to 14.1, then it would go down to 12.2, sometimes less. This problem was amplyfied when the hi beams were on. I had it into a harley shop in south eastern British Columbia, and they fixed it up in a day!! Surprised the crap out of me. The best HD shop I've been to.
what they did was change the battery and a selenoid and relay. I'd love to tell you which ones, but they never wrote it on the invoice. since they did that, it will only drop to 13.5, which is normal.
I'd get the dealer to go online and figure it out, that's what they did for me.
Good luck |

I fixed this problem today! I changed out the Relay connected to the end of the sub-harness attached to the sub fame (looking at the rear of the bike under the seat left of the battery). I switched out the relay with (advanced auto parts) "BWD R3074Z" this relay has a hole that you can attach to the side of the sub-frame with a zip tie!
If anyone needs pictures I can pull my front and rear seats off and take pictures for you! |

i think that is the harness relay you changed. I mentioned earlier in this thread that mine was charging low and when i changed the relay it completely fixed mine too. Might be worth it for people to check their relays first thing if they are having low voltage issues. |
