current flow is from the top of the diagram

(current source) to the bottom of the

diagram (ground).

D

D Only those components that work together

in the circuit are shown. If only part of a

component is used in the circuit, then only

that part of the component is shown.

D Remember:

Entire component

Part of a component

DIAGNOSIS

If the diagram is accompanied by text:

- Read the Circuit Operation before

proceeding with the electrical diagnosis.

- Read the Troubleshooting Hints before

performing the System Diagnosis.

- Tests follow the System Diagnosis

- When performing the System Diagnosis,

be certain that all components

disconnected in previous steps are

reconnected unless otherwise directed.

See Introduction (i) for additional

circuit diagram symbols.
