THE DASHED LINES ARE CURRENT'S PATH IN FORWARD ROTATION.

SOLID LINES ARE CURRENT'S PATH AT ALL TIMES.

NOTE: DIRECTION OF MOTOR ROTATION DEPENDS ON WHICH SMALL

TERMINAL OF EITHER SOLENOID IS CONNECTED TO BATTERY'S

SOLENOIDS TO MOTOR CONNECTIONS

FIGURE-3

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

(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

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

. 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.

With 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, the test on the winch signifi cantly exceeds 70 amperes refer
to your Owners 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.
