Connect negative battery cable.
Statt and operate generator set at rated frequency and voltage.
Move AC CIRCUIT INTERRUPTER switch to CLOSED position. AC CIRCUIT INTERRUPTER light should
light.
Adjust 5,000 ohm potentiometer clockwise and at the same time observe multimeter and AC CIRCUIT INTER-
RUPTER light. AC CIRCUIT INTERRUPTER light should go out at between 1.7 and 2.3 VDC indicating that
AC circuit interrupter relay is open.
Shut down generator set.
Disconnect negative battery cable.
Replace reverse power relay if operation is not as above.
Remove multimeter and test circuit wires. Reconnect wires 158B, 158C, 161A and 161B at reverse power relay.
Raise and secure control panel.
Connect negative battery cable and close battery access door.
Removal.

Inspect ion.
Shut down generator set,
Inspect relay K11 for cracks, loose mounting, and other damage.
Testing.
Shut down generator set.
Remove voltage sensing relay, paragraph 2-59.3.
Set multimeter for ohms and check for open circuits between terminals 1 and 3, and terminals 8 and 6 of voltage
sensing relay.
Check for continuity between terminals 1 and 4, and terminals 8 and 5.
Connect multimeter between terminals 2 and 7 of relay and check for between 1260 and 1890 ohms.
Depress reset button and check for open circuits between terminals 1 and 4, and terminals 8 and 5.
With reset button still depressed, check for continuity between terminals 1 and 3, and terminals 8 and 6.
Replace voltage sensing relay if indications are not as above.
If no repair is needed, install voltage sensing relay, paragraph 2-59.4.
