Diagnosis & Testing: Notes

NOTE: Before testing components, be sure battery is properly charged, all wires are sound and connections are secure. Inspect distributor cap and rotor for cracks or carbon tracking. Turn ignition "OFF" when connecting test equipment or when replacing parts.

CAUTION: Before replacing "defective" parts such as the ignition coil, distributor or electronic control unit, check that the electrical system is operative. Particularly check the oil thermoswitch on the right-hand side of the oil pan and the relay which it controls. Also check all wiring and connectors.
