5.6 Troubleshooting Coaxial Cable
If there is water or other conductive material in the conduit (ie.:
Excessive wire lube) it can change the electrical properties of
the coax cable and cause the system to perform poorly. Moisture
in the conduit may not be detected by the following test. The
only sure way is to inspect the coax and associated conduit for
trapped water.
1. Disconnect all three wires of the coaxial cable at the
electronic unit.
2. Disconnect all wires at the sensing element end of the
coax.
3. Using an ohmmeter, measure between two of the
coaxial cable conductors. Note any reading. Repeat for
all three conductors. All readings should show an open
circuit, (infinite resistance).
4. Check for continuity of each conductor. Short out
two of the coaxial cable conductors and measure these
two conductors at the other end. A reading < 10ohms
indicates a good cable. Move the short to the third
conductor and repeat.
