switches as required (WP 0074
00).
3. Remove tophandler junction
box cover and ensure that
circuit breakers F41, F42, and
F43 are not tripped. Check
wire from circuit breaker F42
to
connector
X181
for
damage.
a. Reset circuit breakers as
required (WP 0076 00).
b. Replace damaged connectors
(WP 0111 00).
4. Remove junction box X184
cover (located on right end of
