Testing

It is often to the technician’s advantage to leave the components intact in the electrical system, and by studying the electrical troubleshooting charts and sche- matics, determine which component is at fault. How- ever, this section will define given components, and the tests that can be performed on those components, when those parts are isolated from the electrical system.

For accurate resistance and/or continuity checks, elec- trically disconnect the component being tested from the circuit.

CAUTION

When testing electrical components with a volt-ohm meter or continuity tester, make sure that power to the circuit has been dis- connected.

Ignition Key Switch (Fig. 8)

The ignition (key) switch has three positions (OFF, START and RUN). The terminals are marked as shown.

The circuitry of the ignition switch is shown in the charts. With the use of a continuity tester, the switch functions may be tested to determine whether all circuits are being completed while the key is moved to each position.

POSITION		CONTINUITY AMONG TERMINALS

1.	OFF	G + M + A
		G + M + A

2.	RUN	B + L + A

3.	START	B + L + S
