KEY INFORMATION

CIRCUIT DIAGRAMS e Circuit diagrams are arranged so that current flow is from the top of the diagram (current source) to the bottom of the diagram (earth). e 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.

® Remember:

Entire component

Part of a component | Ll TERMINAL NUMBER DESIGNATION 50 Battery voltage: Ignition Switch in position Ill

30 Battery voltage: supplied constantly

15 Battery voltage: Ignition Switch in position Il or Ili Battery voltage: Ignition Switch in positions I, II

31 Earth See Introduction (i) for additional circuit diagram symbols

- 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.
