Battery: Service Precautions





1 Take care to connect the battery cables correctly.
If the cables are connected wrongly for only an instant, this will suffice to damage the rectifier in the alternator.

Therefore, always connect:
- the positive battery cable (red) to the positive (+) terminal of the battery
- the negative battery cable (blue) to the negative (-) terminal of the battery.

When connecting an external current source, such as another battery, to the cars battery:
- always connect positive pole to positive pole
- always connect the negative pole to ground.

2 Never connect or disconnect the battery while the engine is running.
3 When boost-charging the battery, disconnect both battery cables.


WARNING
The battery contains acid.


4 Always wear rubber gloves and goggles when doing any work where there is a danger that battery acid might be splashed.



Important: If battery acid splashes into your eyes, rinse them immediately in running cold water for at least ten minutes.


5 Make sure that the battery is always kept upright and horizontal. The acid may run out and cause damage through corrosion.
6 Never place tools or other objects on top of the battery.
