Jump starting the engine from another car's battery (VW Golf 1)

To jump start the engine, connect the positive (+) terminals of the two batteries with a thick wire. Then connect the negative (-) terminals with another wire (figure 26). Instead of the negative terminal, the second wire can be connected to any metal part of the engine that has a reliable connection to the "ground". Remember that failure to observe polarity can completely disable the semiconductor devices of the electrical systems of both cars.



When connecting batteries, please note the following:

• 1. The external battery must have the same nominal voltage as the discharged one.
• 2. The connecting wires must be thick enough to withstand the starting current (about 300 A).
• 3. The wire clamps must have reliable contact with the battery terminals.
• 4. The wires should be connected to the discharged and external batteries at the same time: first connect the positive terminals, then the negative ones.
• 5. If the booster battery is installed in another vehicle, start its engine before starting the engine with the discharged battery to prevent the second battery from being discharged too quickly.
• 6. Reduce both engine speeds to 1000 RPM or less before disconnecting the wires.

Do not disconnect the vehicle's electrical system wires from the battery while the engine is running.
