FUEL LEVEL PROBE TRANSDUCER TEST
1. Check that wires are correctly installed according to the harness
wiring instructions and have not broken, shorted or come loose.
2. The following measurements are made by first fabricating and
then inserting a ‘bare wire jumper’ between each respective
transducer lead to harness terminal (i.e. red to red, black to
black, white to white). If any test fails, stop and contact the
factory.
3. Measure continuity (ohms) of each wire from transducer
connector pin to appropriate harness connector pin. There should
be very low resistance if the wire is intact. If resistance is greater
that 0.7 ohms, then stop and correct connections.
4. Perform the following tests with instrument power ON.
Shut off power and disconnect probe from harness (or
harness from IO interface).
