After stator replacement
Here's the story: Replaced the stator -- bike (VN900 classic) started fine, but with lots of extra noise - grumbling, almost grinding noise at the front of the motor -- went for a 10k test ride, lots of power and responsiveness -- got back, still lots of noise -- unplugged the regulator/rectifier and started the motor, NO MORE GRUMBLING NOISE?? -- plugged reg/rec back in, noise is back -- took the whole thing apart again and pulled out the stator, ran the motor for a couple seconds, with and without the reg/rec plugged in and no noise either way.
I think this isolates the noise to the generator/stator. I see no bare wires, no shorts anywhere. So here are my questions;
- the rotor has a slight bit of play in and out - very slight - could that be a problem?
- the connection plug that Rickstator sent for the 3 white wires coming out of the stator seemed really loose and open - can shorting happen there (outside the oil chamber)? Should these connections be soldered?
- There was no simple way to determine which white wire from the new stator was to be connected to which white wire in the wiring harness; they are all the same. Does it matter? If so, how does one decide what the match is?
I know there a lots of posts on stator issues. I couldn't find answers to these questions. Here's hoping someone can help.
