Battery light remains on. 2012 kymco people gt 200i

[Garym0510]

Before starting 13.1
While starting 12.1
Running 13.8 up to 14.2
Revving stayed around 14
I don't have an option to turn off lights so they are always on.

@Garym, voltage shows normal values.
Now the real search starts.

Since the "rear" part, battery/regulator/generator seem to be healthy, next steps would be to check
-fuses (which one shuts your charging light off?)
-next suspects are handlebar switches
(you sure, NO light switch?)
-front fairing off, which connector switches off your charging light?
Each cable, switch, connector has to be opened to be eliminated from suspects list.
As mentioned already, there should be somewhere a corroded spot on a  +cable which touches ground and illuminates your light.

Pls see link, there is a similar story, to get an idea.

@Garym, one more try..
-up on your regulator are two connectors, one with 3 yellow cables and one with a red and green cable.
1st test
The one with 3 yellow cables comes from stator and produces AC, measure on this three yellow cables
(motor running, connector together, multimeter on AC)
- one yellow to second yellow
- second yellow to third yellow
- third yellow to first yellow
there should be at each try the same voltage shown on your multimeter. If there is one failing, then your stator is demaged.

2nd test
- measure on this second connector with red and green (motor running, connector together, multimeter on DC 20 V)
-there should be during idle an output of 13.5-14.5V on your multimeter, if below 13.0V or over 15V, your regulator is out of service.
-regulator gets pretty warm during idling, that is normal.
