6.9 Checking Voltage at Plug—GP 2500A
See Graphic: wc_gr003146
Electric shock hazard. Only qualified personnel should conduct this
test.
By starting the troubleshooting procedures at the generator output
plug (d), you can determine whether the problem lies within the
generator or the circuit supplying the receptacles. To check the voltage
at the output plug, carry out the following procedures:
6.9.1 Remove the two screws which secure the end cover to the generator
and remove the end cover.
6.9.2 Start the engine.
6.9.3 Using the AC voltage setting on the multimeter, measure the voltage
between the red wire and the white. There should be 120V±10%.
• If zero (0) volts is measured, it indicates a problem with main
winding 2 or the rotor winding.
• If 120V±10% is measured, main winding 2 and the rotor are func-
tioning; continue.
6.9.4 Using the AC voltage setting on the multimeter, measure the voltage
between the brown wire and the blue wire. There should be
120V±10%.
• If zero (0) volts is measured, it indicates a problem with main
winding 1.
• If 120V±10% is measured, main winding 1 and the rotor are func-
tioning; any problems with the receptacles receiving voltage are
in the circuit to the receptacles.
