Diagnostic Aids

The use of a diagnostic service probe offers many advantages in system diagnostics. The most important advantage of the diagnostic service probe method of diagnostics is the ability to observe the operation of a circuit without disturbing the components or connections. This is an important advantage since many circuit failures are vibration or connection related. The diagnostic service probe is designed to firmly hold multimeter test probes to allow for more accurate readings while the circuit is operating. Circuits with bad connections, grounds, or components are easier to diagnose while they are operating.
Diagnostic service probes are for use on 0.35, 0.5, and 0.8 sq. mm (22, 20, and 18 gage) wires only.





The diagnostic service probe must be left on the wire after use. The probe contains a sealant that will protect the wire from corrosion. Do not remove the diagnostic service probe after use.
