The Yellow Battery Charging light is staying lit on my LX277. The battery is remaining fully charged and has been checked at an Auto Parts store. This tractor has the Kawasaki FH500V 17.5 hp motor. The battery cables measure 1.2 ohms resistance. The output from the stator, white leads on the voltage regulator, is showing 33VAC high idle and 13VAC at low idle. The battery registers 12 VDC when the tractor is off and when it is running. The red lead off the Voltage regulator grounded to the engine also reads 12 VDC. Is there something wrong with the Voltage Regulator?
