After replacing the stator and rotor in my 09 1125R my first check prior to start up was for continuity between each phase and the chassis "ground". This is where the madness begins, brand new stator, rotor and I have continuity to the chassis. I put the + lead on each phase wire from the stator and the - lead to bar that the seat hooks to. What, if anything am I doing wrong. I did fire it up and voltage is what it should be. I really would appreciate any help with this before I loose whats left of my mind.

What is the meter showing? High or low resistance? M or K ohm or lower?

Are you measuring with the regulator attached? Or is this just the end of the stator plug?

Where did the stator come from?

The meter was showing no resistance, straight continuity to the chassis. This was straight out of the plug for the stator, no regulator. It's a Rick's stator, I just got it back after it failed. They rewound it under warranty, I do have the upgraded rotor. I also sent the regulator to them, they said it tested good.

The stator would not be putting out correct voltage or charging the bike if all 3 phases had direct short to ground.

Can you upload a picture of the meter with it connected showing this fault?

If you have continuity on the windings to ground, you will have resistance, even if it's only 0.1 ohms. What was your meter reading?
I agree with Terrys - you will not have full charging output if you have continuity to ground on all 3 phases of the stator.

I'll upload some photos this evening. Thanks for the info.

Each phase had the same reading, I did not mention earlier, I have eliminated the "Harley fix" by connecting the stator directly to the voltage regulator. The Active Intake Solenoid is still connected to the relay. Thanks again for the info

Someone please correct me if Iím wrong, but Iíve only ever seen three wires coming out of a stator. I believe the two ends of each series have to be joined in a certain sequence, to get three phase.

Was it Hildebrand that did a thread on rewinding a stator?
If you can find that one, or one of the other threads that cover rewinding a stator, it might be helpful to you.

What is on the other end of that four wire socket you are probing with the meter?

There are generally three whites coming out of a stator. They can be connected in any order. They used a 4 wire plug for the stator, only three terminals are used, the fourth is plugged so dirt doesnt get in. When taking apart the plug you gotta make sure the dead spot is the same on both.

I marked the plug prior to taking it apart to feed the wire up, don't trust my judgment enough to remember how to get it together correctly. The stator was rewound at Rick's due to the original one failing after 100 miles. They said the original one had to much wire around each winding which caused it to make contact with the housing and short to ground. Once I get a new gasket in, I'm gonna take it apart and hopefully I can figure something out with it.

Agreed that the three whites can be connected in any order, but my sometimes faulty memory is telling me that when you have a stator that doesnít have all six pigtails tied together into the three white wires, there is a certain sequence of hooking them together that must be followed. I could be wrong.
The service manual doesnít cover it.

Iím surprised that anyone would ship a stator with six loose wires hanging out, if that is in fact what happened.

PS When I was working on airplanes a while back, I was handed a three phase starter/generator off of something expensive, and asked if I could fix it without a service manual.

I got lost in the damn thing...about six hours later the boss asked me if it was done. I was totally embarrassed to say I had gotten lost in the circuitry, and hadnít yet figured out how it was supposed to work.

I called it a day, and didnít bill the boss for any of it.

Agreed that the three wires coming out of the case can be connected to the regulator/rectifier in any order. When a 3 phase supply is connected to a 3 phase motor it makes a difference, determines which way motor rotates. Reversing any 2 wires changes motors direction.
