When buying a used car that should not be simply examine the condition of body and hear the sound engine. Must also know the power system, such as light rays of which light and overcast when the gas engine anchor lap down. Then the room filled cable.
For cars with age above five years, generally have a lot of interference on the electrical system. In addition to the age of cable have been eaten and the ability to be reduced stream flow.
There are many ways that can be used to find out, whether the electricity the car - generally used car follow the direction 12 volt - are still healthy or not. Of the many ways, the easiest and popular use voltmeter. To want to do that alone, can also use voltmeter. But before doing ways below.
1. Check the engine room when a lot of additional cables that are not standard and not neat, it is likely problematic.
2. Note the positive terminal (+) battery, if many of the cable, the many accessories that require additional power and likely taken with the bypass model.
3. Precise electrical components such as lamp, AC, power window, and others. If everything works correctly, it means that the electricity is still good.
4. When the full load conditions, such as AC followed by light work lamp, audio, and other, increase engine cycles. If the light rays, both in the primary or in the dashboard light or significant increases electrical fan lap faster, there is a problem with the supply of electricity from the Alternator.
5. If it's still can be done like this. Check the battery voltage when the engine is not alive. Conditions of good numbers in the 12-13 volt voltmeter shows.
6. To check the Alternator, turn the engine and all electrical devices, such as large lighting, audio, AC, heating glass and others. Measure the battery voltage. Alternator is still healthy indicates that the battery voltage is 12.8 volt at the number.
7. Check voltage at some point the flow of electricity to be positive. Such as lamp, lighter, and other components. Look for the section allows you to check the voltage with the electrical voltage difference is not more than 0.5 volt.
