When buying a used car (mobkas), it should be considered not enough to examine the condition of the body and hear the engine sound. it must also know electrical system, including conditions such as bright lights when it is gassed and dimmed when the engine turns off, then, a room is full of cables.
Cars over five years of age are generally more susceptible to interference on the electrical system. Besides the cables are due to brittle with age, ability of drain current is reduced.
There are various ways of being able to used to find out, whether electric cars are generally used car to adopt 12 volt direct-still relatively healthy or not. Of the many ways, the easiest and popular is the use of voltmeter. For those who want to do themselves, it also can use the voltmeter. However, previously, do the ways below.
1. Check the engine room when a lot of extra wires are not standard and not tidy. There is a possibility, this is problematic.
2. Note the positive terminal (+) battery. If many wires, it reveals a lot of additional accessories requiring electricity and possibly taken with bypass model.
3. Check Thorough electrical components, such as lights, air conditioning, and power windows. If everything works well, it means that electricity is still good.
4. Test when the full load conditions, such as AC followed by turning on the lights, audio, and others; then increase the engine speed. If the light rays, both in the headlights or the dashboard light of a significant scintillation or growing fast electric fan rotation, meaning that there are problems with electricity supply from the alternator.
5. If you're still curious, do this. Check the battery voltage when the machine is not alive. Good condition is indicated by figures in the voltmeter show 12-13 volts.
6. To check the alternator, start the engine and all electrical devices, such as large lighting, audio, air conditioning, and heating the glass. Measure the voltage at the battery. Alternator is still healthy, it would indicate a good battery voltage, ie the number of 12.8 volts.
7. Check the voltage at some point that becomes the flow of positive electricity, such as coils, lamps, cigarette lighters, and other components. Find the section allows you to check the mains voltage with no voltage difference more than 0.5 volts.
