j110tlcur charging system question

[cosworthrs500]

I was out on the lake last weekend when the tach dropped to zero rpm with the engine running. I shut down and looked under the dash to make sure no connections came loose. Everything was solid. I then put a meter across my battery terminals and fired up the motor to find that it wasn't charging across any rpm range. My question is; can the stator fail and cause this no charge situation, or is it the rectifier that fails first taking out the stator. The reason I ask is the rectifier was replaced last fall… when it went bad last time the tach would randomly jump around, Now it just sits at zero. There is no change in tach operation when I put the gray tach signal wire to the yellow lead coming off the rectifier. The resistance on the stator brown/yellow to brown is 570ohms. Just trying to get some input before I order any parts.
Thanks,

My thought is that you are jumping to conclusions, assuming it is the stator. I'd be more apt to jump to the conclusion that it is the regulator/rectifier.

The rectifier was my initial thought also but I have bench tested it and all is ok… so I don't think I'm jumping to conclusions.
I guess I forgot to mention the bench test.

Both forward diodes are fine, only read one way
Resistance between both yellow wires and ground is in the 2.88M ohm range.
Red to ground reads over limit M ohm.
Gray to ground reads 10.16K ohms.
Gray to red reads over limit M ohms.
Gray to both yellows reads 2.29/2.27 M ohms.

This is why I'm leaning towards no output from the stator scenario. Just thought maybe someone has a similar experience.
I do not have a DVA adapter so I can't check the DVA voltage when running. I will swap out the stator this weekend with a used spare and see what happens
