Bad stator? - May 16, 2008, 01:51 PM



Battery is not charging.Does this look like a bad stator?

Well you see, Norm, itís like thisÖA herd of buffalo can only move as fast as the slowest buffalo. And when the herd is hunted, it is the slowest and weakest ones at the back that are killed first. This natural selection is good for the herd as a whole, because the general speed and health of the whole group keeps improving by the regular killing of the weakest members. In much the same way, the human brain can only operate as fast as the slowest brain cells. Now, as we know, excessive intake of alcohol kills brain cells. But naturally, it attacks the slowest and weakest brain cells first. In this way, regular consumption of beer eliminates the weaker brain cells, making the brain a faster and more efficient machine. And that, Norm, is why you always feel smarter after a few beers.-Cliff Claven

Only way to test is via a continuity check. And depending on how many different windings you have, you have to do it correctly.


R.I.P. Eric. You were truly like a younger brother to me. May you live on in all those you helped and reached out to help. You are truly missed!

tfinch: well, actually, if he did, that's fine cause it's in the pockets!

: Mike, can you feel bubbles floating around in there?

tfinch: Bubbles! Yes! Gurgly bubbles!

yeah you'll need to check for winding resistance and insulation breakdown.

Everything should be outlined in the manual.

What are your symptoms that led you to suspect the stator?

I would always suspect something else before that. Did you test the voltage coming out of it when the bike was running...? That is the easiest thing to do first.

Hooked up a voltometer to the (new)battery when the battery was fully charged and I would watch the voltage take a dive like Sidney Crosby.I've replaced the battery,rewired the harness and replaced the R/R.I have already ordered a new stator,I couldn't figure out the testing procedure from the manual.I'd rather just replace the usual suspects than take the time trying to diagnose when I have no clue what I'm doing.

Can anyone look at that pic and get suspicious of it?

whoa whoa put away the credit card and take out the multimeter...

Throwing money and parts at electrical issues is always a bad way to go about trying to fix them.

Get the bike back together. Get the wiring diagram and start systematically with your voltage and resistance checks. A visual check on an electrical component can only get you so far.

I usually find the service manual electrical checks to be fairly straightforward. Just do them all in order as listed.

Yeah,I totally get you,but I'm an idiot and an even bigger idiot when it comes to electrical issues.Just easier for me to replace stuff and hope I get lucky.

The dark coils indicate more heat than usual. Meaning more than likely the stator or stator wires are shorted. Not sure if this stator is a three phase stator but the test are really easy to do with the stator installed.

But no sense in testing now since you are buying a new one. Good luck with it.
Does your bike also have a rectifier? You should replace both the stator and rectifier.
If you replace the stator and the old rectifier is bad, you will blow your new stator.
Just a though.
Carry on.

Yeah,got a new battery and rectifier/regulator.
