Check:

Is the direction of rotation of the motor
correct?

Are cables satisfactorily fixed?

Are cable entry points to motor terminal box
satisfactorily waterproofed?
Spray the cable gland, cable entry points and motor
terminal box with anti-corrosive waterproof coating
"CRC 3013 Soft Seal" or equivalent.
2.7 POWER CONECTIONS TO DC MOTOR
The main power system is a two cable, ungrounded,
fully insulated, negative return system. The motor is
of the isolated earth type. This system is selected to
minimise electrolytic corrosion problems.
The DC motor has four power terminals, marked
"A1", "A2" , "D1" & "D2".
Terminal "D1" should be connected directly to "-"
terminal on the battery, see wiring schematic in
Appendix C.
Terminal "A1" should be connected to terminal "M2"
on the starter (solenoid) box. When powered, the
windlass should rotate clockwise.
Terminal "A2" should be connected to terminal "M1"
on the starter (solenoid) box. When powered, the
windlass should rotate anticlockwise.
See Table 2.1 to select the appropriate cable size for
power supply. The recommendation assumes that
the cable insulation has a minimum temperature
rating of
90°C.
Cable lengths given are from the battery terminal to
the terminal on the motor, via the solenoid box, and
then back to the battery.
Where a portion of cable runs through the engine
room, a size increase should be made as indicated.
After connecting the cables, spray all terminals with
anti-corrosive waterproof coating, "CRC 3013 Soft
Seal" or equivalent.
