2.
The transducer isolation check is performed as follows (see Figure B):
A.
Disconnect the transducer cable from the electronics.
B.
Make the circuit connections illustrated in Figure B.
C.
Probe all the conductors and note the voltage with respect to the shield. All readings
should be less than 0.5 Vdc. The yellow (Y) wire should also be isolated from the green
(G) wire. Connect the "low" test lead to Y and probe the Blu and G wires with the "high"
lead. Again, the meter should read less than 0.5 Vdc; if not, consult factory for service.
Similarly, check the isolation between the Blu and G wires.
