(G 3.7A, G 5.6A and GS 5.6A Models)
See Graphic: wc_gr000944
Functional Output
6.10.1 Confirm that the voltage selector switch is in the 120V position.
6.10.2 Measure the three receptacles labeled 120V and confirm that voltage.
6.10.3 Measure the 240 Volt labeled receptacle and confirm that the voltage
is zero.
6.10.4 Turn the main breaker off and switch the voltage selector switch to
120/240 Volt position.
6.10.5 Turn the main breaker on and verify 240V at the labeled receptacle
and 120V at the three 120V labeled receptacles.
Switch Output
Worn, dirty, or damaged contacts can affect the operation of the
voltage selection switch and result in no, or low, voltage at receptacles.
Test the selector switch using an ohmmeter.
6.10.1 Remove all wires from switch, then open main circuit breaker and
check for continuity across switch terminals as shown.
6.10.2 Measure from middle terminal to terminal on either side. Meter should
indicate continuity (a) (contacts closed) to one side and no continuity
(b) (contacts open) to the other side.
6.10.3 Repeat for each of the three center terminals.
6.10.4 Change switch position and repeat the check.
Replace switch if testing shows terminals on each side are either both
open or both closed.
