Cause:
The motor controller is faulty.
Fault Isolation:
In the case of the lateral and vertical thrusters, simply thrust only one
thruster, in one direction, at a time until the symptom reoccurs. In the case of the port and
starboard thrusters (since they work together), first determine if the failure is in the forward
or aft direction. For example: If the failure occurred in the forward direction, you can
determine which thruster failed by utilizing the LBV‟s rotate function. Rotating the LBV
clockwise causes the port thruster to thrust forward while the starboard is thrusting aft. By
using this feature, the troubleshooter can run each thruster in one direction at a time. The
faulty thruster needs to be replaced.
Note:
This failure can occur with grabbers and external lighting when these devices are
being operated, but the fault isolation would be the same.
