subject to suspicion. Successive cutting of the cable end until leakage disappears will prove successful in
many cases.
CAUTION! Prior to cutting the cable for any of the above reasons, a
careful visual examination should be made for any signs of physical
damage.
With both ends disconnected, the tow cables should measure between 100 Mega-ohms and infinity
between conductors with a 500 VDC Meg ohmmeter. When using a Simpson 260 Multi-meter, all cables
wire-to-wire or wire-to-shield should measure infinity. Any leakage on the multi-meter indicates cable
leakage.
6.3.8.4 Damaged Tow Cable Connector
The towfish has a trip line that prevents the vehicle from hanging up on a snag. When the line trips, the
cable connection to the vehicle disconnects exposing the high voltage pins to seawater. Pin corrosion will
start to occur as long as power is still applied. If the power is not immediately removed, and the cable is
not immediately retrieved and the connector flushed out with fresh water, there may be permanent
damage to the connector. This will require cable re-termination.
