Test wires and socket associated with GEN 1 indicator light by testing for continuity between switch
terminal A2 and socket XDS1, and switch terminal A3 and socket XDS1. If multimeter does not indicate
continuity exists on both of these wires, replace light and wire assembly (paragraph 4-25, b.).
Test wires and socket associated with GEN 2 indicator light by testing for continuity between switch
terminal B2 and XDS2 socket, and switch terminal B3 and XDS2 socket. If multimeter does not indicate
continuity exists on both of these wires, replace light and wire assembly (paragraph 4-25, b.).
Test ground wire by touching one probe to switch box load terminal LO and touch remaining probe to AC
GROUND terminal E2 on switch box. If multimeter does not indicate continuity, replace associated wire
(paragraph 4-25, e.).

Set multimeter for continuity testing.
Set switch lever to GEN 1 position.
Touch one probe to switch terminal A1 and remaining probe to switch terminal L1. Repeat test between
terminals A2 and L2, and terminals A3 and L3. If multimeter does not indicate continuity exists between
each pair of terminals, switch is defective. Notify higher level of maintenance.
Set switch lever to GEN 2 position and repeat step (3) above, substituting terminals B1, B2 and B3 for
A1, A2 and A3.
