Normal or strange charging system symptom ?

[Eliseo Monteverde]

Hello GSR brothers !!!!
Here I?m again with eletrical questions.

One month ago, I replaced the stator and R/R unit.
The reads with the voltimeter at the battery terminals were:

At idling speed--13.5 V.
At 5000 RPM-- reads increased to 14.4 V.

That it sounded good.

...Today I checked the charger output again, and read was:

At idling speed----14.2 V.
At 5000 RPM ----reads decreased to 13.3 V.

Battery is always at 12.5 V when the engine is off.
I have the three yellow wires attached to the three alternator wires.
The black with white tracer lead from R/R is wired directly to the battery negative terminal.
The stator is producing 75 volts AC between each of the three legs when the engine is running at 5000 RPM.
Wiring connections, switch contacts, fuse holders, internal fuse box connections, grounds, are cleaned.
Battery is 2 years old.

The question is, if my R/R is dying or what is wrong?

Thanks in advance.

it could be the battery, 2 years old is getting pretty old for a motorcycle battery.
have you checked the electrolite level in the battery? (water level in the battery)
and have you installed a extra ground wire from the regulator to the ground terminal of the battery?

ground

Instead of running the ground straight to the battery, ground it to the R/R body and then run a ground from there to the battery

did ya check/clean all the connections in the charging system???
