Wanted to take my bike to work today for the first time this year and when I went to start it all I got was a couple slow revolutions and that was it. Had to hook up a charger for a coupke of minutes and it took right off. Checked the volts reading on the new speedo and it wouldn't go over a 12.9v charge rate a 2000 rpm.

So the first thing I did was check the new Cycle Electric stator and it looked good. .1-.2 ohms and no short to ground so I decided to start the motor and check the ac out put. Should have been between 36 and 40 volt ac @2000 rpm. I only got 12 v so, having another stator in the tool box I decided to swap it out only to find that this one put out even less @10.5 volts @2000 rpm.

So I preceded to make some phone calls only to get a little more disappointed to find that no one could give me any relative experience in this situation. So I decided to get a new oem rotor and give it a shot. $140 and crossed fingers. To my amazement my charging system was now putting out 14.2 @1500 rpm.

Hard to believe that the magnets in the rotor became de-magnetized.

Has anyone ever ran int this before. The only real loss was time invested. Never heard of this before but I gues if it can happen it will.

So tomorrow I get to ride to work. Ye Ha!!!!!!

 

I've seen one of the stator bolts come out and trash the magnets but I've never heard of them losing their magnetism.

That's a new one to me!!!

 

Usually the voltage regulator is the more common failure in the charging system.

 

Yes very common, but not this time.

 

WOW!

That's a first for me dude. Never heard of one doing that.

Griz

 

Can happen if you drop the rotor or smack it with a hammer...

 

Could you be a little more specific as to what will happen if you drop or smack. The only thing I could think is broken or loose magnets. Somehow mine became demagnetized.
Thanx...

 

If a magnet is struck or hammered it loses magnetism. Not sure but I think that's why the manual reads not to use an impact when removing primary chain equipment.

 

Thanx, Totally unaware of that.... That would explain it then.......

 

Never had a problem taking mine off with an impact.
