Ezgo txt overcharging issue

[Savoy43A]

Is there a way to check the S/G to see if the DF terminal is shorting internally??


Cart is running fine but when you check voltage at battery resting is 12.5 to 12.8 but charging with engine running is close to 19v -

- replaced starter generator
-replaced voltage regulator (2 times)
- replaced solenoid
- checked wiring installation and terminals
- green (DF) wire from S/G is good
- green (DF) wire removed the Volts are still close to 19volts, correct me if I’m wrong but shouldn’t it drop down to battery volts with green wire removed? Is there a way to check the S/G to see if it’s shorting the DF terminal internally?
