One of the most common wiring problems is current leakage. This way you can create operating conditions for the motor, under which the battery voltage is measured.
Anti-theft system, immobilizer, central locking. Take, for example, power circuits.

Now you only need to find out which consumers are connected to this section of the electrical circuit, after which the wiring itself is diagnosed. The author of the video is Alexander Shestopalov. Contacts are oxidized or burned. If there are cracks in the case, it is possible that electrolyte is leaking out of them, which contributes to the destruction of the battery. If you do not know whether power is or should not be supplied at the moment to the section of the circuit under study, voltage.

A little history of Daewoo Matiz
This car model has been produced since 1998. To date, 2014, the third generation of Daewoo Matiz (M300) has already been released. Matiz of the first generation (M100? M150) and second (M200? M250) Hatchback has 5 seats. All models are equipped with a manual gearbox, and the consumer has a choice of engines: 0.8 liters or 1. After a slight restyling of the car in 2012 (the M200 model was released), in China it was called Chevrolet Lechi. Also there, the car once again underwent minor modifications and became known as “Baojun Lechi” with engines of 1.0 liters (69 hp) and 1.2 liters (86 hp).

Engine compartment mounting block
The engine compartment mounting block is located on the left side, near the battery.
Fuses under the hood
F1 (50 A) - ABS.
F2 (40 A) - constant power supply to devices when the ignition is turned off.
F3 (10 A) - fuel pump . If the fuel pump does not work when you turn on the ignition (you cannot hear the sound of its operation), check relay E, this fuse and the voltage on it. If there is voltage at the fuse, get to the fuel pump and check if voltage is supplied to it when the ignition is turned on. If it does, you most likely need to replace the fuel pump with a new one. When installing a new one, also change the pump module filter. If there is no voltage to the pump, most likely the problem is in the wiring or the fuel pump circuit breaker (for example, in an installed alarm system). The wires could be frayed under the seats, in the harnesses, or there might be poor contact at the joints/twists.
F4 (10 A) - ECU power supply, fuel pump relay winding, ABS unit, generator winding at start, terminal B from the ignition coils, speed sensor.
F5 (10 A) - reserve.
F6 (20 A) - stove fan . If the stove stops working, check this fuse, its fan motor by applying 12 V voltage to it, as well as the handle and cable of its drive going to the heater tap. If the heater blows cold, this cable could fly off; it is located on the driver's side near the center console under the dashboard. If the heater speeds are not adjustable, also check relay C under the hood. It could also be an air lock.
To remove air from the system, drive up a hill with your front end up, open the expansion tank cap and release the gas. On a hot engine, be careful when opening the reservoir cap. It could also be a problem with the heater core or clogged air intake pipes.
F7 (15 A) - heated rear window.
If the heating stops working, check the fuse, as well as the contacts in its socket. If there is poor contact, you can bend the terminals. In many models, due to the lack of a relay in the rear window heating circuit, the power button receives a large current load, so it often fails. Check its contacts and if it no longer locks in the pressed position, replace it with a new button. You can get to it by removing the dashboard trim or pulling out the radio. It is best to install a relay, thereby relieving the load on the button. In some models, a relay C under the hood is installed on this button, check it.
Also check the threads of the heating elements for breaks; broken threads can be sealed with a special glue containing metals. It could also be the terminals at the edges of the glass, a poor grounding connection, or the wiring from the rear window to the button.
F8 (10 A) - right headlight, high beam . F9 (10 A) - left headlight, high beam . If your high beams stop lighting when you turn on this mode, check these fuses, fuse F18, the contacts in their sockets, the lamps in the headlights themselves (one or two could have burned out at once), relay H in the engine compartment and its contacts, the steering column switch and its contacts. Often the contact in the switch connector is lost, disconnect it and check the condition of the contacts, clean and bend if necessary. Also check the wires coming from the headlights for breaks, short circuits and insulation damage. The negative on relay contact H may also disappear due to oxidation or burnout of the track in the mounting block.
To replace the lamp in the headlight, disconnect its connector with wires, remove the rubber cover (boot) from the side of the engine compartment, squeeze the “antennae” of the lamp clamp and remove it. When installing a new lamp, do not touch its glass part with your hands, as Hand marks will darken when turned on. The lamps in the headlights are double-filament, one lamp for low and high beams; for the dimensions, separate smaller lamps are installed in the headlights.
F10 (10 A) - right headlight, low beam . F11 (10 A) - left headlight, low beam . Same as high beam, except F18.
F12 (10 A) - right side, clearance lamps.
F13 (10 A) - left side, clearance lamps, license plate lighting lamps . If your side light goes out, check these fuses and relays I and their contacts. Check the serviceability of the headlight lamps, connector contacts and wiring.
F14 (10 A) - air conditioning compressor clutch (if equipped) . If your air conditioner does not work and the clutch does not move when you turn it on, check this fuse and relay J, as well as the power button and its contacts, and wiring. The movement of the operating clutch should be audible through a characteristic sound when the air conditioner is turned on. If the clutch works but cold air does not flow, the system most likely needs to be charged with freon.
Explanations for Daewoo Matiz diagrams.
At first glance, the electrical circuit diagrams discussed in the Matiz car section cause complete confusion. After the general diagrams of domestic cars that are familiar to us, the diagrams of foreign cars are a dark forest. However, this is not quite true. Taking the circuit apart into parts has its advantages. And if you carefully study this section on reading electrical circuits, then everything becomes clear and simple. Take, for example, power circuits. If you do not know whether power is or should not be supplied at the moment to the section of the circuit under study, voltage. Just look at the designation of the power cord and compare it with the table below. Let's say you are looking at the light switch circuit, you looked at the diagram, and it is connected to wire number 30. This means that power, its positive source, regardless of the position of the key in the ignition switch, is constantly present on this conductor. The same goes for the fuse for this circuit. By marking it on the diagram, we find out the maximum current load that it can withstand - in this case 80 Amperes, where it is located - in this case in the fuse box in the engine compartment and through which contact - in this case 1, which connector - here as an example connector C203. In addition, we immediately determine the color of the harness in which the desired wire is located. For specialists, it is not particularly difficult to remember the letter indices of the designations. Moreover, there are not so many of them. And in practice, understanding the diagrams every day, they quickly get used to and understand the usefulness of these notations. If you yourself want to find and fix a breakdown in any Daewoo Matiz electrical equipment circuit, this page will help you.
Possible wiring faults
What malfunctions can occur in the operation of the electrical circuit:
- Broken wiring. This problem can lead to current leakage; we have already described its diagnosis in more detail. To prevent wiring breakage when laying new wires, they must be additionally insulated.
- Short circuit. One of the less common problems is diagnosed using the same tester.
- Voltage fluctuations - it can be either low or high. Such malfunctions are usually associated with incorrect operation of the battery or generator, or, less often, additional devices.
- Contacts are oxidized or burned. Contacts usually oxidize as a result of prolonged use or when equipment operates in humid conditions. Oxidation can occur on the connecting plugs - this problem is solved by cleaning them with sandpaper or a wire brush. If we are talking about burning, then it is most likely caused by power surges in the network. Therefore, you first need to solve the problem with overvoltage, and then change the burnt contacts.
