Vehicle Damage Warnings

IMPORTANT VEHICLE INFORMATION

- Always turn off the ignition or disconnect the battery for resistance tests. (If this is not done the tester may destroyed).

- Always disconnect the rpm sensor plug for compression tests. (If this is not done, hazardous high voltages and insulations damage to the ignition coil, high-voltage distributor and ignition leads may result).

- The specified ignition coil (refer to Order No.) must not be replaced by a different coil.

- Never connect a suppression capacitor to ignition coil terminals 1 and 15.

- Never connect ignition coil terminal 1 to ground for burglar alarm. (Ignition coil and control unit may be destroyed).

- Never connect the positive battery terminal or a test lamp to ignition coil terminal 1 (The control unit will be destroyed).

- Never disconnect the ignition lead from ignition coil terminal 4 to high-voltage distributor terminal 4 while the engine is running.

- Voltage flashover from ignition coil terminal 4 to coil terminals 1 and 15 must not occur. (Control unit may be destroyed).

- To avoid destruction of the control unit, the secondary circuit of the ignition system must be suppressed with at least 4K ohm, the original distributor rotor with 1K ohm suppression resistance having to be installed.

- Disconnect Digital Motor Electronics (DME) control unit only after turning off the ignition.

- Flashover or disruptive discharge in the area of the high-voltage distributor cap (poor insulation) may destroy the control unit.

- Never disconnect the battery when the engine is running.

- Battery polarity reversal could lead to destruction of the ignition coil and the DME control unit.

- External engine starting with than 16 V or with a boost battery charger is not permitted.

- When pulling off the connectors, e.g for mass air flow sensor, throttle switch, injection valves etc., make sure the inside gasket is not lost.

- Always follow the accident prevention regulations when working on the fuel system.
