5.0 TROUBLESHOOTING
Problem Possible Cause Solution
Windlass does not rotate.
No electric power to controls.
Make sure the isolator switch for the
windlass controls is ON.
Check the fuse on power supply to
controls.
Make sure the wiring is correct and
check it for damage.
If there is more than one type of control
(pendant unit, footswitch, helm switch),
check them all in an effort to isolate the
problem
Check isolator switch and fuse on
Variable Frequency Motor Control, if
supplied.
Check the power supply to controls
from the source, step by step, and
identify the point where it stops.
Incorrect or incomplete wiring.
Check wiring against diagrams
supplied.
No power supply to the capstan. Check power supply lines.

Faulty thermistor relay
To confirm, check resistance between
terminals 21 and 22. If it is above 500
ohms, contact Maxwell.
Damaged thermistors on the motor To confirm, check resistance across
thermistors, it should be between 50
and 500 ohms. When doing that, do
not use voltage.
Windlass is not able to pull
the specified load.
Motor voltage does not match the
power supply on board.
Check name plate on the motor. If
confirmed, contact Maxwell.
Hydraulic relief valve not set
correctly.
