SUBJECT:
PROPER PROCEDURES WHEN PROBING WIRING FOR
DIAGNOSIS ON ALL CADILLAC MODELS
Occasionally, proper diagnosis of an electrical problem requires probing electrical circuits for voltage or resistance measurements. Most often this can be
accomplished by probing the metal terminal at a connection point. However, there are times when it is easier to probe individual wires with a sharp
instrument.

NOTICE:
If a wire is probed with a sharp instrument and not properly sealed afterward, the wire will corrode and an open circuit will result. Refer to
Figure 1.
