- Always turn off the ignition before disconnecting the pin block in the vehicle's electronic circuit. It is best to disconnect the battery cable from the terminal so that there is no voltage surge that can damage sensitive electronic devices.
- Before carrying out electric welding work, disconnect the battery, and disconnect all connections of all electronic control devices.
- If the car, after body work, is sent to the spray booth, the temperature there can briefly reach 95°C. For a longer period of time (up to 2 hours maximum) the temperature must not exceed 85°C.
- The engine can only be started when the machine has cooled down to normal temperature.
The figures schematically depict (from left to right), how to connect the appropriate measuring device for voltage measurement (IN), current (A) and resistance (Ohm). A circle with an arrow depicts a measuring device, and «consumer» is, for example, a lamp, an electric motor, etc.
