Personally I'd like to see you re-measure the voltage coming out of the stator "without being connected to anything" (out of circuit) @ 5000 rpm.

Ok thats the first thing I will do when I get home from work ..now its a little tricky to hold the throttle to keep the revs at 5000 rpm while doing test .but if I putthe choke on that gets me just above 4500 rpm will that do ? Or should i adjust idle a little so rpms are axactly at 5000
 
Masking tape and a sharpe.

Label a pair, label the second pair 2, label the third ;)....

Meaning what ? Lol

Meaning some electrical noise may be interfering with your electronic meter readings causing them to bounce around or you are using the wrong scale for the readings you are making. rustybronco's last suggestion for reading between the three pair of stator leads on the 200Volt AC setting at 5,000 RPM may tell you a lot. If the stator reads differently on the three stator leads or low you need not bother with the R/R at this time. It should read about 70 VAC on all three pair combinations.
 
Put the leads in a pair of wires, start bike, rev engine, look at meter. Wash rinse and repeat for the other two pairs :)

Put three dots in a triangle on a piece of paper. How many times can you connect the two leads from the volt meter up to those three dots? ;)

When I did this teat last nite , all the numbers were in the 20's once the number was 50 ..
But ill be happy to run the test again ...
 
It's the jumping around that bothers me... Shouldn't be doing that.

Make sure you have a good connections AND, remember what I said about the wall socket? There was a reason for saying what I did. Care to guess why?
 
My '78 and '79 with split Rectifier and Regulator both cooked it's stator. This test will give you the best answer as to its condition. Always double check your results and leave your pride at the door. There are no stupid questions except the ones you don't ask.:D What he said about the erratic readings. Maybe it's time to do all the required harness, plug switch and ground maintenance. It might eliminate some tail chasing. Check your plug caps, they would be the first suspect for radio frequency noise.

There should be 9 ways to test these wires ? No ?

Well we would like to see how accurate the tester is ??
 
YEP, and to see if it's jumping around.

Three... When the meter is in the A.C position lead polarity means zip. Alternating Current goes positive, then negative, then positive, then negative.... W-R-R ;)

The only thing remotely frustrating is when you don't read what we say. Everything is said for a reason.

Can't help if we don't have the answers we require.
 
What's so confusing? put your imaginary 'leads' on the points I described in that drawing. That's exactly how you will be connecting the 'real' leads up to your bike.

Questions?

Im trying to give you all the answers to your queations ..
When I get home I will pulla socket from the wall and take a reading. Then wil label wires from the stator A, B & C and try the test over ..
Again thank you

Rusty, this is the reason I allway just focus on quick test until a direction can be found. The average joe coming to Gsr and electrical problems just has a difficult time with following the few or revised stator pages.

In addition it has been well stablished that the only stator test that is even close to being conclusive is the leg to front stator tests. The rest are only conclusive if they fail. If they pass it does not mean much.


This particular poster has some very strange quick test results and a separate r and r. I see no reason to leave that old pair of r's on the bike and so no point to test it with until it is replaced.

Jim, rather than replacing both units at once, I'm trying to show him how to test the stator.
He has a R/R that is known good and will fit so that's one portion out of the way. BUT, if he can't make sense of how that R/R should be connected to a stator that has five wires then I will try and make him understand as best as I can.

We got him settled down, he knows what we've asked and I've relinked him to the quick test in your signature.

Got to get him comfortable with what he doesn't understand first.

Oh, and to me, measuring the stators output 'is' a quick test. :)
