Okay so i came to figure out that my tractor isnt charging at full capacity but it is charging, So what would cause this? the VR? when the battery is unpluged the lights are dim but still on and when i checked it with a bolt meter it was at 12.5 volts which is far off from the 13.6 volts i should have? so whats up with it and how do i tell?
 
Thr generator/alternator make be putting out all it can-full capacity. Say it is 12 amps max and the light are drawing 18 amps. Nothing wrong. Check the voltage with the battery in and the lights off. I grew up with a 36 ford that could keep up with the lights but if I ran the radio too, the battery ran down and I was stranded.
 
Hello Pat CT,
With engine running at fast idle battery voltage for a 12V system is 13.8 to 14.2 volts at 70 degrees F. Fully charged battery at the same temperature is 12.6V
Check battery voltage at fast idle, it should be 14V + or- .2V at 70 degrees F.

Hello Pat,
If you checked the voltage with the engine runnimg and it was 12.5V that is battery voltage, your system is not charging!.

it has to be charing somewhat? becuase the voltage hasnt droped at all in the 2 weeks ive been constantly using it? with and without the lights. and when i disconect the battery the lights still work? so it has to be somewhat?
 
With the battery disconnected and the lights on. The generator should be able to carry at least 10amps and hold 13.8V.
I suspect the regulator is set too low. In addition the belt is likely slipping due to being glazed and the pulley being worn.
Over tightening to try and compensate is just going to burn the bushing/bearing out of the pulley end of the generator.
