8.1 ELECTRICAL DIAGNOSTICS (HW3000/L MODELS)
General Electrical Check
Check for Tripped Duplex Circuit Breaker(s)
Outlets Above the Breaker Indicate
Resolve Overload Problem to Ensure Safe Operation
After Electrical Load Resolved Wait Several Minutes
(for Thermal Breaker to Cool) Push to Reset Breaker
If Cannot Reset, Replace Breaker
Start Engine and Run at No Load
Check Engine Frequency = 61.5 to 63 Hz
Adjust Governor, if necessary
(see Manual Section "Governor Adjustment")
If Frequency Still Out of Range,
see Engine Diagnostics Section
Check Voltage Output at NEMA 5-20R 120V
Perform "120V Circuit #1 Check"
Check Voltage Output at NEMA 5-20R 120V
Perform "120V Circuit #2 Check"
