Stator....ugh!??

Hello folks,

Let's start by telling you what we are dealing with here...


2006 900 Classic
brand new battery about 1 month ago

a few days ago it started a whirring kind of sound... i liken it to a wheel bearing good bad in a cage.

yesterday dead battery...crappy push start to get it home.. but i digress..

read the stator sticky on here ( great information by the way)

went about testing my stator this afternoon..

Fluke 87 meter
results as follows

Idle

12 volts
10.5 volts
13.1 volts

Roughly 3k rpms
15.3 volts
13.5 volts
16.5 volts

I'm thinking bad stator?

Tested the reg/rec.

Black probe to black,red probe to w1 = 0.L ( i think this is infinte)
Black probe to black,red probe to w2 = 0.L
Black probe to black,red probe to w3 = 0.L

red probe to black, black probe to w1= 2.047 ohms
red probe to black, black probe to w2= 2.077 ohms
red probe to black, black probe to w3= 2.126 ohms


this leads me to believe the rreg/rec is good.


please someone tell me if this is all correct?

Where would be the best place to purchase a new stator and gasket?

Anyone care to chime in on this for me?
I just want to order the stator and gasket right away so my bike isn't off the road to long.

In the stator sticky, perform the operation in section 6, test 2.

Also, in your reg/rect test, you are missing some tests and results.

Post back with your results.

I see where i missed the parts of the reg/rec test i will redo it tommow.
I didnt figure i needed to do the short to ground test after seeing the voltage results,but I will conduct that test tomorrow as well.

I'll post results again tomorrow.

Tested the reg/rec.

Black probe to black,red probe to w1 = 0.L ( i think this is infinte)
Black probe to black,red probe to w2 = 0.L
Black probe to black,red probe to w3 = 0.L

red probe to black, black probe to w1= 2.078 ohms
red probe to black, black probe to w2= 2.108 ohms
red probe to black, black probe to w3= 2.154 ohms

Black probe to red, red probe to w1 = 2.101 ohms
Black probe to red, red probe to w2 = 2.138 ohms
Black probe to red, red probe to w3 = 2.141 ohms

red probe to red, black probe to w1 = 0.L
red probe to red, black probe to w2 = 0.L
red probe to red, black probe to w3 = 0.L

Short to ground test

w1 = 0.L
w2 = 0.L
w3 = 0.L

I believe 0.L is infinte resistance so its not shorted to ground

I didn't do the violtage test again as i think i got that right the first time.

It seems to me that the stator is bad, but not shorted to ground and the reg/rec is good.

You could have one that is vibration sensitive in that it only shorts when the engine is running.
But by your AC readings (I am guessing that is what you gave in post #1 as you did not specify) it looks as if the stator is shorted.
Reb/rect. looks OK for the most common failures.

So I should just replace the stator?

Thanks again for the advice!

If you would like to verify the problem, you could remove the side cover, then put your black meter lead to the case and put your red meter lead to any white wire, set to read ohms, then tap on the stator, tug on the wires and see if you can get your meter to respond.
Here is where an analog ohmmeter shines. It is easy to see needle deflection vs. a display that jumps around. But give it a try because it is always nice to be able to zero in on the fault.
Post back with any questions.

I finally had some decent weather and got my stator replaced.
After the install I ran all 3 tests on it again and it checked out good.
I am thankful for all of the advice and help I recieved here.
I'm attaching a few pictiures of my old stator.
You can see the lovely burned to a crisp parts of the stator in the pictures...
Im hoping for some good weather in the coming days to get out and ride it some.

You have a good case there where the problem only shows when the engine is running.
No short to ground by the ohms test but AC voltage is low.
Also a good demonstration that "load" is not the problem here or else all windings would be cooked.
