D.8.1 Testing the Towfish

The towfish block diagram is shown in Figure D-13.
D.8.2 Checking the Telemetry Link to the Towfish
Turn the TPU on and check the LOCK LOSS and ERROR lights. The lights
should be off. If they are on or flickering, there is a problem. Again, a telemetry
link problem could be one or more of the following: towfish fuse failure, cable
assembly problems, miswire, open, using too long a cable, using wrong type of
cable, or a failure in the towfish.
