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, fi rst 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 isolated ground terminal. (See Figure 1). Motor

should now run.

To reverse the direction of rotation:

1. Attach jumper wire from F-2 to motor terminals. (See Figure 2).

2. Attach wire from positive (+) battery terminal to 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

negative (-) battery terminal at the motor isolated ground terminal. This avoids burning the

motor

terminals.

CAUTION: Do 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 amps 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 ap-
proximately 65 to 70 amps. If after following the procedure outlined, and the test on the winch sig-
nifi cantly 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.
