Safety rules
CAUTION!
To prevent personal injury or damage to sensitive electrical components:
^ Switch ignition OFF before connecting or disconnecting components or test equipment.
^ Connect or disconnect Battery only with ignition switched OFF to prevent damage to Mono-Motronic Engine Control Module.
^ Before disconnecting a Battery, ALWAYS ask for the correct radio code (if equipped with anti-theft radio).
^ If engine must be cranked but not started (for compression testing etc.) disconnect the Ignition Coil Power Output Stage (N157).
^ DO NOT use battery booster longer than one minute and DO NOT exceed 16.5 Volts.
^ DO NOT wash engine unless ignition is switched OFF.
^ Switch ignition OFF when arc or spot welding.
^ Before towing vehicles with suspected defective ignition system, disconnect terminal -1- (green) on Ignition Coil
^ When installing noise suppressors, use ONLY 1000 Ohm suppressors far high tension wires and 5000 Ohm suppressors for spark plug connectors.
^ DO NOT replace distributor rotor marked R1 with different type.
^ If vehicle is heated (paint booth), DO NOT start engine until cooled to room temperature.
