Figure 3-8 Connect Winch Motor Cable to Controller (J2)
VERIFY WINCH OPERATION
First, verify that the motor power cable is connected to J2 of the Controller Assembly. After you
make the battery power connection to the controller, use the special magnetic slide switch to test
if the winch will pay out and reel in when the switch is activated. Placing the magnet side down
in the groove should result in movement of the winch drum. You should hear a click from the
relay contacts. The winch drum should move. Next slide the switch in the groove to control
direction of the cable movement. The sonde need not be attached for this test. To stop winch
movement, pull the magnetic slider away from the groove. This manual test verifies winch
movement. If the winch does not behave as described above, check all connections, check
battery voltage and repeat the procedure.
