(2) Check continuity of overload contacts between points L1 and L2, and Ml and M2. If continuity exists from both
checks, go to step (3). If open circuit exists, reset or replace overload contacts.
(3) Check continuity of wires between points 1A2and M1, M2 and I2, E1 and E2, E2and H2, H2 and R1, H1 and R2, R2
and S2, S1 and Q1, Q1 and P2, P1 and N2, and N1 and 1A1. If continuity exists from all checks, replace magnetic
starter (1M). If open circuit exists from any check, repair or replace faulty wire(s).
e. Close (ON) circuit breaker P10 or P11 at main switchboard and check voltage at inputs to contactor 2M
across terminal pairs 2A1 and 2A2, 2A1 and 2A3, and 2A2 and 2A3 for 440 Vac. If voltage across all terminal
pairs is 440 Vac, go to step g. If voltage across any terminal pair is not 440 Vac, repair or replace wire(s) from
inputs of 1M to inputs of 2M.
CAUTION
Before checking reverse operation, insure that anchor cable is unwound at
least 15 feet to prevent winch damage. This can be done with or without
power. (See TM 55-1930-209-14&P-1 para 16-21, 16-22.) See caution on free
falling of cable.
f. Position ON/OFF switch to ON position and depress reset and reverse buttons. Check output voltage of reverse
contactor (2M) across terminal pairs 2B1 and 2B2, 2B1 and 2B3, and 2B2 and 2B3 for 440 Vac. If voltage across any
terminal pair is not 440 Vac, go to step g. If voltage across all terminal pairs is 440 Vac, go to step h.
g. With reverse button depressed, check voltage at magnetic coil of contactor (2M) across points J1 and J2 for 440 Vac.
If voltage is not 440 Vac, go to step (1). If voltage is 440 Vac, replace magnetic starter. (1) Open (OFF) switchboard
circuit breaker P10 or P11 and make continuity checks as follows:
WARNING
Make sure anchor winch control panel is electrically dead before making
continuity checks. Redtag main switchboard circuit breaker P10 or P11
with: "WARNING DO NOT ACTIVATE. REPAIRS BEING MADE."
(2) With REVERSE button depressed, check continuity of reverse between points F1 and F2 and check
continuity of FORWARD switch between points Q1 and Q2. If all checks indicate continuity, go to step
(3). If any check indicates an open circuit, replace faulty switch(es). (3) Check continuity of overload contact
between points G1 and G2. If continuity exists, go to step (4). If open circuit exists, reset or replace
overload contact.
(4) Check continuity of wires between points 12 and J1, J2 and G1, G2 and K2, K1 and F2, K2 and F1, and F2
to 02. If continuity exists from all checks, replace magnetic starter (2M). If open circuit exists from any
check, repair or replace faulty wire(s).
h.
Check continuity of wires from contactor 1M to contactor 2M between points 1B1 and 2B1, 1B2 and 2B2, and 1
B3 and 2B3. If continuity exists between all checks, go to step i. If an open circuit exists, repair or replace faulty
wire(s).
