Technician Safety Information

CAUTION: To prevent injuries to persons and/or damage to the fuel injection and ignition system components, observe the following points.

- Do not touch or disconnect ignition wires when the engine is running or cranking at starter speed.

- The ignition must be switched OFF when disconnecting or connecting injection and ignition system component wiring, as well as test instrument cables.

- If the engine requires cranking at starter speeds but without starting, e.g. when checking compression, disconnect the harness connector from the Engine Speed sensor.

- Do not connect a capacitor (of any description) to the ignition coil terminal 1 (-).

- Do not replace the 1000 Ohms (identification: R1) distributor rotor with a different type even for Radio Frequency Interference (RF1) suppression.

- For RF1 suppression purposes only, high tension leads must have a resistance of 1000 Ohms and spark plug connectors must have a resistance of 5000 Ohms.
