stator?

[bikehandle]

I have had what I thought was a stator issue. I connected a multimeter across the pos & neg on the batt, and was getting 13.7 at idle and as I increased the rpm the volts would go down to about 13.2 at 5 grand then climb agian a little bit after. the best chargeing was at idle. I changed the R&R and it went down to about 12.9 volts from above at idle. I pulled the stator and checked it and all three legs checked good. no discoloration, no burned spots (I replaced the stator 7 years ago when I restored the bike) the only thing diffrent is I replaced the headlight with a 110 or 120? dont remember witch. so anyway why the low voltage? I thought when the R&R went, the voltage would spike and if it was low voltage it generaly was the stator? It has me baffled? (thoughts)?

Hard to say, best bet is to run the full Elecctrex test, but my first thoughts are either a bad battery, bad ground (how did the black wire at the r/r to wire harness connector look?).

or, if you pulled the stator out, did you check to see if it was grounded to the case first?

The stator was grounded to case. and the black wire looks new. the batt was new in july. all connectors are in realy good shape, I clean them every year. I dont understand why the voltage drops with increase of rpm. ???

Do the Ohms check on the stator, and make sure you have the 3 readings between 0.5 & 2.0.

[Walt_M.]

The stator should not be grounded to the case.

[QBS]

Walts right.  There should be no continuity between any of the three stator output wires and the engine side cover that the stator mounts on.  Such continuity indicates a bad stator.

Uhh...that's what i said... lol

I understood what Lucky was saying. I was making refrence to testing while in the bike and doing continutiy check. the main frame of the stator would have to get ground to case to work. but thanks anyway.

no actually, there should be absolutely no contact between the three stator wires and the stator body at all, so whether the body is grounded or not makes no difference.  The body of the stator is not a part of the electrical circuit.

[bikehandle]

Yes, thats what I said

[Lucky]

i'm getting a headache...

[bikehandle]

Sorry, Lucky.
I was just looking for some help.
Thanks anyway!

Oh I was just playing..

I'm confused about weather you realise that if any of the stator wires have any continuity to ground indicate a short..

of course the stator core itself is grounded, but that is no indication of weather the stator is good...

No continuity to ground on stator wires.First thing checked! I am starting to think it must be the r&r? the highest it charges is at idle, almost 14, then drops off with an increse in rpm down to about 13. then at 5 grand it increses a little.
check me if I am wrong but if one leg was burnd on the stator it would have low voltage at idle but would still increse some with rpm? instead of going the other way?
Hope you understand what I am getting at!

Could you give me a link to elecctrics flow chart?

Try this link for the electrex chart.

I'll bet you have a bad RR.

[bikehandle]

Thanks for the help!
I am haveing trouble downloading the electrex chart. this computer is older than dirt and not wanting to do pdf files. It looks like the fates are agianst me on this project!(but then whats new!)

You can also do an AC voltage check from your stator to see if it is functioning properly.  Test each of the three wires (while running) to see that output is the same and it will increase with rpm if it is good.  That pretty much confirms the R/R as bad if your AC voltage output is fine.

Louie, old buddy!
Great Idea! Its coming out in ac?or dc? I know, stupid but I gotta ask. My understanding of electricity ranks up there with my understanding of women and tax forms!

Sorry!
I cant read either! Duh!
