Diagnosis
Note. If you probe a wire with a sharp instrument and do not properly seal the wire afterward, the wire corrodes and an open circuit results.
Diagnostic test probes are now available that allow you to probe individual wires without leaving the wire open to the environment. These probe devices are inexpensive and easy to install, and they permanently seal the wire from corrosion.
