Vehicle Damage Warnings

^ Always turn off the ignition or disconnect the battery for resistance tests (if this is not done, the measuring device may be destroyed).

^ Always disconnect the speed sensor plug for compression tests. (If this is not done, dangerous high voltages and insulation damage to the ignition coil, high-voltage distributor and ignition leads may result. In addition, the remaining spark plugs of the 2nd ignition circuit could ignite.)

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

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

^ Never connect ignition coil terminal 1 to ground for the burglar alarm. (The ignition coil and control unit could be destroyed.)

^ Never connect battery plugs 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 during operation.

^ Voltage flashover from ignition coil terminal 4 to ignition coil terminals 1 and 15 must not occur. (The control unit could be destroyed.)

^ In order to avoid destruction of the control unit, the secondary circuit of the ignition system must be suppressed with at least 4k Ohm, whereby the original distributor rotor with 1k Ohm suppression resistance must be installed.

^ Disconnect the DME control unit and ignition output stage plugs only after turning off the ignition.

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

^ Never disconnect the battery when the engine is running.

^ Battery polarity reversal could lead to destruction of the ignition out put stage, ignition coil and DME control unit.

^ External engine starting with more than 16 V or with a boost battery charger is forbidden.

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