Ramsey Winch DC 34,9 - Manual (Page 18)

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 termi-
nals. 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 cable
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.
