Troubleshooting the Electrical Circuit
Electric shock hazard:
Disconnect the cable puller from the
power supply before servicing.
Failure to observe this warning could
result in severe injury or death.
See the wiring diagram. Use a continuity checker to
check the electrical circuit. Lack of continuity in the fol-
lowing procedure indicates that a repair is necessary.
1. Unplug the puller.
2. Set the switches to ON.
3. Place the probes of the continuity checker across
the following terminals of the cable puller and force
gauge. All of these pairs of terminals should have
continuity.
To check the switches:
A and B
Q and R
S and T (220 volt models only)
X and Y (220 volt models only)
To check the connectors:
G and A
H and D
I and J
K and S
L and O
M and N
U and N
V and R
W and K (120 volt models only)
W and T (220 volt models only)
To check the bridge rectifier:
C and D
E and F
To check the ammeter:
O and P
To check the motor:
C and E
If the motor fails this check, inspect the motor compo-
nents (brushes, armature, and wires). Replace any parts
that are worn or damaged. Replace both brushes if
either brush measures less than 3/8" long.
