Bad Stator - confirm?

[allojohn]

Just to add to the confusion I turned the headlight off and and now get 13.80 @ 2,500 rpm. and 14.00 @ 5,000 rpm.

My head is spinning - I'm going for a cup of tea........

Yep, R/R disconnected and at idle (1,100 rpm).

OK 8 volts seems pretty high considering you are at idle, Jury is still out on those stator tests

In Revised Phase A tests is the red from the R/R disconnected?

No it is NOT disconnected. All connections should be as you intend to run it. You are measuring the amount of voltage drop there is in the conection when supplying maximum power.

Was that with R/R disconnected? What RPM?

If you don't have bad voltage drops in the Revised Phase A tests it is looking more like a bad stator.

I just checked the legs to ground voltage at idle and got around 8 volts on each.

Sorry they should all be publicly shared now. I just open this as a new account to start restoring files that were previously lost.

Thanks - got it.

I am confused though, if I keep the R/R connected how can I get the meter in there? All my connections are insulated spades.

That's not at all consistent with the other results you've posted.

You know you have to use the AC scale to read the stator, and the DC scale to read the battery and output of the regulator, right?

Not trying to insult you, but it looks to me that you're trying to read the stator voltage using the DC scale of your meter.

I certainly think I was using AC voltage. My meter has the ~ symbol when in AC mode. I'm disregarding earlier tests as bullsh!t.

Don't worry about insulting me - I know I'm a dumba$$ as far as this stuff goes. I just don't want to replace the stator and find it's not the problem.

Those aren't awe inspiring numbers- what kind of R/R do you have?

Electrosport - again about 6 month old.

I unusually don't leave the key on for 30 sec

I was fiddling around with the meter.

You are charging some so the next thing do do would be to do Revised PHASE A of Stator pages .

Sunday morning....

Battery right off charge.
Key off - 13.10
Key on - 11.90 (after 30 sec, lights on)
Idle - 12.20
2,500 - 12.80
5,000 - 13.00
Key off - 12.50

Resistance between legs 0.8 - 1.0 ohms
All legs to ground my meter reads OF (overflow, this is good right?)

That is GOOD.

Measured A/C volts at 4,000 rpm reads 65-70 between each leg.

While you were running did you also check if the leg to ground voltages were also zero.

My tiny mind is now thinking the stator is OK so maybe my nearly new battery is going bad?

I unusually don't leave the key on for 30 sec, only a few secs to read the meter so the drop to 11.9v might not be that bad. You are charging some so the next thing do do would be to do Revised PHASE A of Stator pages .
You need to measure the voltage drops between R/R(+) and Battery(+) and well as R/R(-) and Battery(-) at 5K RPM . These voltages should be less than 0.2V.

I don't think I did the tests correctly first time and am not comfortable with this multimeter yet. I'm reading the manual again. More to follow tomorrow.
Thanks for your help so far gents!

Simple proceedure with an ohm metere. Set to the lowest ohm setting (you should see the omega symbol on the dial) put the leads together and you should read close to zero. Across the stator close to 1 ohms. it should be very high going to ground.

[allojohn]

You do need to recharge the battery but it doesn't seem as it it is charging much at all.

If you are getting 0 ohms to ground on the stator test then you have a short and the stator is no good.
