Run the transducer cable back to the instrument. Avoid fluorescent
lights, engines, radio transmitting equipment and the speed
transducer cable. The transducer cable should also be kept clear of
bilge's, where possible, and be secured at regular intervals.
Note: The transducer cable must not be shortened. Shortening
of this cable will affect the performance of the unit. For further
information, please contact Autohelm or an authorised agent.
If the bronze through hull (Z118), in hull puck (Z117) or retractable depth
(Z120) transducers are to be used, the following modification must be
carried out to the transducer lead.
1.
Using a pair of wire cutters, remove the moulded plug from the end
of cable.
2.
Strip the outer cable back 38mm (1.5in).
3.
Using a pair of cable strippers, remove 10mm (3/8in) of insulation
from each wire.
4.
Using a suitable crimping tool, attach a 1/8in spade connector
(supplied) to each of the wires.
5.
Connect the wires to the instrument in accordance with the following
table.
