Test Procedure For Motor - RAMSEY WINCH RAM-LOK DC 34,9 Manual De Funcionamiento, Reparación Y Mantenimiento

TEST PROCEDURE FOR MOTOR

The Ramsey Winch motor is a (4 pole-4 coil) series
wound 12 volt or 24 volt DC motor.
The 4 pole-4 coil feature provides high torque at low
speeds.
To test the motor to determine if it is functioning
properly, first securely fasten the motor to a bench
or work surface so it will not jump or move around
during test procedure (the starting torque of motor is
high).
1. Connect a jumper wire (at least a number 6
wire) from F-1 to "A" motor terminals (See
Figure 1)
2. Attach a wire (at least a number 6 wire) from
positive (+) battery terminal to F-2 motor ter-
minal. Ground negative (-) battery terminal to
motor isolated ground terminal(See Figure 1).
Motor should now run.
To reverse the direction of rotation:
1. Attach jumper wire from F-2 to "A" motor termi-
nals (See Figure 2).
2. Attach wire from positive (+) battery terminal to

TEST PROCEDURE FOR MOTOR
F-1 motor terminal. Ground negative (-) battery
terminal to motor isolated ground terminal (See
Figure 2).
NOTE: Always attach battery wire solidly to motor
terminals. Make and break the connection of the
negative (-) battery terminal at the motor isolated
ground terminal.
CAUTION: D

COULD BECOME DAMAGED
The motor running idle on the bench will draw 55
amperes and must run free and easy. If the ampere
draw is more than 60 amperes and the motor runs
rough or has a strange sound, it should be replaced.
With the motor attached in place on a winch (less
cable on drum) the ampere draw should be approxi-
mately 65 to 70 amperes.
If after following the procedure outlined, the test on
the winch significantly exceeds 70 amperes, refer to
your Owner's Manual for trouble shooting sugges-
tions on the mechanical portion of the winch.
See Figure 3 for the solenoids connection to the
motor and the battery.
