would you replace a stator with these readings?

[don_gibb6512]

Stator test:

Red lead of MM to output wire/ Black lead to output wire @ 5K rpm = 64v across all three wires

Ohm reading across all 3 pairs = .4 ohm

Ohm reading across 2 wires to engine casing = .4 ohm
Ohm reading across 1 wire to engine casing = .3 ohm

Looked, can't see anywhere that the wires from the stator are crimped, bad, nothing.

So it is making voltage...

Ohm reading across 2 wires to engine casing = .4 ohm

So it's pretty much shorted to ground, it can't make any voltage at all.

Your readings conflict with each other, are you using an autoranging multimeter incorrectly?

[bonanzadave]

Nope. 64V AC right ? Why do you ask ? Charging issues ? What is the DC charging voltage at the battery at or above 2k RPMs ?

There is another thread with the OP is doing exactly the same thing. They should take a video to see what they are doing wrong.

The video is a good idea. The DC V output at the battery was 12.8v at 5k rpms. The RR had a burnt spade connector to ground and the tests on it were indicative of a failed RR. Because of the readings I got was why I asked about the stator in the first place. I don't understand it either. It would seem that there is some kind of failure in the wiring to ground on the stator that would cause the Ohm readings to be the way they are but I'll be damned if I can find it.

EDIT NOTE: I apologize on my typo. This should have been 12.08v @ 5k rpms, not the original post of 12.8v.

It's an Electrosport stator, if that means anything.

Yes, it was 64v AC across the stator wires.

I'm using a Radio Shack 23 range LCD Digital Multimeter and to the best of my knowledge, I'm using it correctly.

I ran these tests 3 times to be sure I was consistent on the readings.

Thanks Would you replace this stator?

No. I would cut out those RR connectors. Replace them with some quality splices and try it again. Run a dedicated ground wire from the RR right to the - battery. If that dont work I would send a PM to Duane for a new RR.

U are measuring resistance between the legs to ground when the stator wires are open right?

12.8 at 5K RPM is doing something.

Could you please do a Quick Test?

Sending Duane the $ for a new RR tomorrow. I'm redoing ALL connectors in this circuit. What bites is that I did that the LAST time. Bought a Klein crimper, used dielectric grease and soldered the connections that didn't HAVE to be removed to do testing. Used new wire, new connectors, tried to do everything right and yet this still happened. ARGH!!! The Stator papers say that the ohm readings across the pairs on the stator should be .5-2v but mine was .4 and the ohm reading from the wires to ground are bad if it reads anything between 0-100 ohm. Since mine are .4 and mostly .4 on the wire to ground, I assumed that the stator was bad. Is this not the case? What does that say about the Stator paper results then? I'm confused.

Don

Going to bed. Gonna shoot pool tomorrow night and do something that I'm actually good at. Cheers.

There are two methods of wiring a stator Delta and Y.

I'll say this maybe there is an issue.

If your stator is wired in a Y configuration it is possible for it to be grounded and still produce power. That is because the center of the Y is considered a neutral and even though it is generally left floating, maybe it is being grounded as part of the way the stator is wound.

The GS1100E manual shows a Y configuration.

Maybe that part of the test should be removed as now I'm not certain if it allways applies especially in a Y configuration.

If you read any voltage (while running and unplugged) from stator wires to ground (casing) buy a new stator.

sorry his reading are fine; check the manual if you don't believe me.

Just check factory manual and the readings below are not in there. This is a ground in the stator halfway thru one coil. Should be tested while running to conform. If he doesn’t want to do a running test, don’t.
Ohm reading across 2 wires to engine casing = .4 ohm
Ohm reading across 1 wire to engine casing = .3 ohm

I'm taking about this statement you made above. Yes the issue of stator shorts to ground is being discussed and I raised the possibility that it is Y configuration stators.

It is a Y (wye) configuration. And it will put out AC power from wire to wire if not plugged in to the regulator. My point is a ohmmeter isn’t the best way to check windings, ohmmeter could read metal filled oily residue or moister. Voltmeter won’t lie on a running test. I’m done.

I agree, trying to measure 0.5 ohms with $10 ohm meters and dirty connections is none to good. Also it is hard to mistake 60-80 VAC.
