Description
Generac / Guardian Voltage Regulator – usually marked F9719 on part. Has (6) 1/4″ spade terminals for wire connections.
Replaces the following part numbers:
81918
83049

0F97190SRV
The 83049 series AVR has been discontinued by Generac / Guardian, and replaced with 0F97190SRV. It looks virtually identical and works the same at a lower cost!
A.C.Voltage Regulator
Used in all current production R.V. products except variable speed units. Also used on air cooled Home Stand-by units. 0F9719, 083049 and 083048 are virtually the same, except the 083048 has no cooling fins on the back of the regulator. These regulators can be interchanged, but the 083049 and 0F9719 are thicker due to the cooling fins and will require longer bolts to replace an 083048.
IMPORTANT:
After installing the new voltage regulator, determine if the frequency is correct. Set mechanical governors to 62Hz at no load. Electronic governors set to 60Hz no load. After determining that the hertz are correct, measure the AC output. The voltage should be 124VAC at 62Hz with no load or 120VAC at 60Hz with no load. If the voltage is either high or low, adjust the brass screw in blue trim potentiometer next to the red LED to the correct voltage.
