Tag and disconnect electrical leads to voltage reconnection switch (16, FIGURE 2-16).
When removing the voltage reconnection switch, use extreme care not to drop
the attaching hardware down on the generator unit. Serious damage to equip-
ment could occur.
Remove screws (11) and (14), washers (12), nuts (13) and (15), and voltage reconnection switch (16) from
output box assembly.
Remove screws (17) and mounting bracket (18) from output box assembly.
Testing.
Remove voltage reconnection switch, paragraph 2-64.2.
Set multimeter for ohms and check voltage reconnection switch for continuity. Refer to Electrical Schematic
FO-1 (S-8 Circuit Schedule) to determine switch circuits made to corresponding switch positions.
Check continuity of switch circuits in all three switch positions.
If open circuit is indicated in any switch position, voltage reconnection switch is defective and must be replaced.
If replacement is not required, install voltage reconnection switch, paragraph 2-64.4.
