Ramsey Winch RE 50,7 - Manual (Page 11)

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 terminal. Ground
negative (-) battery terminal to motor housing
(See Figure 1). Motor should now run.
To reverse the direction of rotation:
1. Attach jumper wire from F-2 to “A” motor terminals (See
Figure 2).
2. Attach wire from positive (+) battery terminal to F-1
motor terminal. Ground negative (-) battery terminal to
motor housing (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 housing. This avoids burning the motor
terminals.
CAUTION: D
O NOT RUN THE MOTOR FOR A LONG PERIOD OF TIME
IN FASHION MENTIONED ABOVE
,
BECAUSE THE MOTOR 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 rope on
drum) the ampere draw should be approximately 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 suggestions on the mechanical
portion of the winch.
See Figure 3 for the solenoids connection to the motor and the
battery.
