City Car 119

When buying a second hand car, which should be considered not enough to examine the condition of the body and hear the engine sound. You have also known electrical system, including conditions such as bright lights when gassed, dimmed when the engine turns off, then, a room full of cables.

Cars with 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 drain current is reduced.

There are various ways that can be used to find out, whether electric second hand cars are generally adopt 12 volt direct-still relatively healthy or not. Of the many ways, the easiest and popular is the use voltmeter. For those who want to do themselves, also can use the voltmeter. However, previously, do the ways below.

1. Check the engine room when a lot of extra wires that 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 that require electricity and possibly taken with bypass model.

3. 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 Rev the engine speed. If the light rays, both in the headlights or the dashboard light of a significant or growing fast electric fan rotation, means 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, 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 would indicate a good battery voltage, i.e. 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 that allows you to check the mains voltage with no voltage difference more than 0.5 volts.

When system A / C (air conditioning) the car is turned on and audible sound ‘Sttt’ in long period, freon mark is reduced or discharged. “The Freon is a liquid, but in the system A / C turned into gas through the development process with high pressure. It was then that the nature of chemical substances contained tetra-flu or octane get colder,” said Hendrik, a specialist shop owner A / C Vent’s.

No adverse effects to the hardware A / C or car when freon out. Conversely, if the freon until the end means that there are errors in the hardware. “In the system A / C, freon will never run out. Up to happen, it means that there are components that are leaking (usually in the hoses, evaporator, condenser),” explained Hendrik.

To maintain the condition of the component A / C durable, do the draining freon once a year and try to use the original freon. There are several brands such Kalton freon , Klea, Duracool and more.

In addition to treatment once a year (or every 20,000 km), system A / C also takes care preventive to work a maximum and durable.

These preventive measures
1. Spin machine. Keep the rpm is not too high (below 4,000 rpm) while driving. Because the component A / C was not created to move in high rotation.

2. Turn off the A / C. When the car did not stop because of traffic jams (waited more than 10 minutes), preferably A / C turned off. This relates to the nature of Freon that had characters must always move by air circulation.

3. Do not be too long. Freon will evaporate and become its original (liquid) if old is not used. As a result, capacity can be reduced drastically due to vulnerable condenser make the connection A / C brittle.

4. Beware of sharp odor. The smell of smoked cabin attached to the back and attached to the evaporator. Increasingly accumulate and cause sour-smelling air into the cabin.
