5. Opens normally occur at connectors, terminals and splices.
6. Use the diagnostic service probe and a multimeter to diagnose circuits that contain 18, 20, or 22 gage wires. The diagnostic service probe causes a
minimum of disturbance to the circuit wiring and connections.
Sneak Circuits
Understanding sneak circuits can help in quickly diagnosing electrical problems that can, at first, seem very complicated.
A sneak circuit can be defined as an unplanned complete circuit. This type of failure is different than a short circuit.
A sneak circuit can occur when more than one component is using the same ground path or power feed. Sneak circuits can happen if a common ground is
lost, a fuse is blown, or a wire is grounded between components.
