Technician Safety Information



Ignition and High Tension Components:

WARNING: The ignition system operates at high power and voltages. It is dangerous to come in contact with the high tension circuit - the ignition coil, spark plug caps and distributor cap.

CAUTION: Avoid sparking when working on the fuel system, especially when working on injectors.




Switch ignition off before:
- Connecting and disconnecting test instruments
- Connecting and disconnecting connectors.
- Taking readings with an ohmmeter.

High Tension:

HIGH VOLTAGE:




Dangerous voltages are present at all points in the system, including connectors etc.

Battery:

WARNING: While the battery is being charged an explosive mixture of oxygen and hydrogen gases is formed. Smoking, welding, grinding or other activities involving sparks or naked flames are prohibited in the vicinity of a charging battery. Batteries must be charged in a well ventilated area.




When testing components it is important that battery voltage is normal (approx. 12 V). If necessary, a battery charger can be connected during testing.

Connect battery charger to the battery terminals. Charge battery for approx. 10 hours at the recommended cur- rent - maximum 6 A.

Example: If the battery is marked 520 A a charge current of 0.01x520=5.2 A is recommended.

A higher than recommended charge current can damage the battery.

NOTE: Boost charging (with a high current or voltage above 16 V) will damage the battery and is prohibited.

Cleanliness:




Cleanliness is particularly important when working on the fuel system. Clean fuel line connections thoroughly before disconnecting.
