| I think the vision puts out 45 amps? What does that mean.
I was out to day 57 had the grips on low very over cast day and cars just don't see me so on comes the HID and yes I had my heated jacket on. Going thew side streets is was charging at 14.2 and thats normal for my bike. Stopped at a stop sign the first time the amp gauged stayed at 14.0 never did above 40 for the next 7 miles came to the next stop signed and down to 12.2 left sign and up to 14.2 and I shut the grips off and the jacket next stop sign down to 12 again. Ran it up to 40 for a good 10 miles and back down to 12. At 70 it was up to 14 but I don't under stand the way the charging system works. Normally the HID doesn't make any difference or does the jacket.
By the way dunlop tires don't like wet leaves in corners. They tend to slid out on me. |

Ruskin, Fl | Wet leaves are like ice. I don't think any tires like them. The max output of the charging system is is 50 amps, but that is not a idle. The alternator puts out AC current and converts it to 12 volts DC. It only produces 17.5 volts AC at idle and 38.5 at 2000 RPMs. Mine will drop below 13 sitting at a light if I am holding the brake. |

Same here, if I am at idle with the brake lights on, it drops down to 12. If I rev it over 1k RPM it will raise back up to 14+. Most bikes that I know of don't start charging until they are over 1k RPM. |

| Hmm, the last time I looked at my Vision or for that matter any Victory Freedom engine they are running a stator/rotor setup and not an alternator. I may be wrong about the current but I believe that the current coming out of the stator/rotor is DC and it then runs to a rectifier which converts excess current that is not being used by the electrical systems into heat, hence the cooling fins on the rectifier. |

LaPorte,Tx. | John, there is a good chance the stator is going bad. Mine started to go bad on a return trip last summer. Volts dropped to ~13.5, I shut off he PIAA lights which on mine are 55w and the HID and the voltage jumped back up to 14.2v. By the time I got home, if I turned on the PIAA lights, it immediately dropped to 12v. The next day, the stator wouldn't put out any current. Take some short hops around the block, stay close to home until you get the issue figured out. I had over 50k miles on the bike when mine went bad. Good luck. |

Memphis | I've got an '08 approaching 50K on the odo and am keeping a close eye on the voltage meter. So far so good but the stator is constantly on my mind. (I'm still on my original battery also.) I talked to a Victory engineer at the AVR and he said they re-designed the stator with the 2011 models to make it more efficient. I asked if the new stator would retrofit to the previous models and he thought it would. I'm hoping my '08 lasts until the new ones get into the pipeline and then change it out under warranty if need be. Biggest hassle I've heard with the stator going out is it may take weeks to get a replacement. Just a heads up. |

I may be wrong about the current but I believe that the current coming out of the stator/rotor is DC and it then runs to a rectifier which converts excess current that is not being used by the electrical systems into heat, hence the cooling fins on the rectifier. Looks like the stator puts out AC and the R/R converts the current to DC.

Indianapolis, IN | Travelin Man - 2010-10-24 8:25 PM Hmm, the last time I looked at my Vision or for that matter any Victory Freedom engine they are running a stator/rotor setup and not an alternator. I may be wrong about the current but I believe that the current coming out of the stator/rotor is DC and it then runs to a rectifier which converts excess current that is not being used by the electrical systems into heat, hence the cooling fins on the rectifier. TM, I'm not responding to your comment to nit-pick, only to eliminate any confusion as it may play in to the original question and to clear up this same confusion that has been spoken here on the forum in the past. To put it bluntly, you couldn't be more wrong. 1. All the Vic bikes, as well as most modern motorcycles use a 3 phase AC charging system with a rectifier/regulator to convert the 17v-38v AC output voltage to 12 volt DC for the bikes DC electrical system. 2.The reason for the fins on the rectifier is because whenever you manipulate electrical current, particularly converting voltage you create heat due to inefficiencies. The fins are there to dissipate this heat so that the rectifier doesn't self destruct. 3.There is no "excess current" being produced by the alternator to get rid of, The charging system produces and supplies current based on demand by the componants using the electricity, up to the 50amp maximum of the alternator's capacity. 4. Some people like to get hung up on the terminology used to describe the parts of the charging system. Technically any charging system that is producing AC current as its primary product is an Alternator (AC-Generator). All alternators have two main parts, a moving part called a rotor, and a stationary part called a Stator. The stator is the focus of many a conversation because it is the most likely part to fail and therefore many people think the bikes generator is a "stator" and not an alternator. The other half of the alternator is built into the engines flywheel and therefore some overlook the other fundamental part, the "Rotor", because it is also the flywheel. Even in the Victory repair manual they refer to the charging system as an "Alternator, Permanent Magnet / 3 Phase / Full Wave Rectification". The only reason I am presenting this explanation is that rather than try to constructively respond to John's question you chose to belittle his choice of terminology, and worst of all you did it without any true understanding of the system that was referred to in the question. HMMMMM, my guess is that you haven't looked at your bike or its service manual at all when it comes to the topic of the charging system or you wouldn't have made the statement above. Now to respond to John, I second Vision Tex's response. The Vics have had a little bit of history of failed stators. I don't think it is uncommon for the voltage to drop on the Volt meter when you are at idle, particularly when accessories are turned on. But when the engine is running above say 1500 rpms, regardless of road speed, the voltage should be just above 14 on the gauge. This shouldn't take any time. It should run up to 14 or better within just a few seconds of revving the engine. Again keep an eye on the trend, especially when riding without accessories. If you are seeing anything below 13.5 volts with normal riding something is probably wrong. By the way there have been other threads on this same topic, do a search and read what others had to do. If I remember correctly a number of owners have had to have bad stators replaced. Good luck and keep us posted. |

Ruskin, Fl | I was confused about that too Travelin Man. I copied the specs right from the service manual. I had all ready typed stator, but the manual calls it an alternator. Figured I'd get called out on it. They do show the resistance specs for the stator, so I looked up the definition of "stator"
The stator is the stationary part of a rotor system, found in an electric generator, electric motor and biological rotors.
Depending on the configuration of a spinning electromotive device the stator may act as the field magnet, interacting with the armature to create motion, or it may act as the armature, receiving its influence from moving field coils on the rotor.
The first DC generators (known as dynamos) and DC motors put the field coils on the stator, and the power generation or motive reaction coils on the rotor. This was necessary because a continuously moving power switch known as the commutator is needed to keep the field correctly aligned across the spinning rotor. The commutator must become larger and more robust as the current increases.
The stator of these devices may be either a permanent magnet or an electromagnet. Where the stator is an electromagnet, the coil which energizes it is known as the field coil or field winding.
An AC alternator is able to produce power across multiple high-current power generation coils connected in parallel, eliminating the need for the commutator. Placing the field coils on the rotor allows for an inexpensive slip ring mechanism to transfer high-voltage, low current power to the rotating field coil.

| Okay, I checked my own repair manual and it looks like I'll be eating crow for dinner!
I guess I considered an alternator a completely separate component from the engine such as is used in a Honda Goldwing (GL1500 and GL1800 as the GL1200s did have a built in stator/rotor) or as in an automobile.
I should have known to stay away from any discussion regarding motorcycle electrics! |

Yep.
All I know is that our Vision is fully capable of running the HID headlight and two full sets of heated riding gear at the same time.

New Orleans, La, | In a You Tube video by Arizona Victory the host states that because Victory mounts the stator to the primary cover as far away from damaging heat as possible, why did/do so many early models suffer stator failure? Has Maw Vic resolved this with subsequent updates?I ask because mine just failed with 70K on the odo. :-(

Its a smarter way to the stator over that other V twin By the way charging has changed and bike is running and charging great |
