Electrical System Description:
The electrical system of the VAZ-2114 is a single-wire negative type. This means that the negative (-) cable coming from the battery serves as the common ground for all devices. The positive (+) wire runs from the battery to the devices and is connected to ground through the control switch. All electrical components and devices are powered by the vehicle’s alternator.
Main electrical system faults:
* Slow starting or failure to start the engine due to a low battery or a faulty starter.
*Lighting problems such as dim or unlit headlights can be caused by faulty bulbs, fuses or relays.
*Poor windows, mirrors and other amenities may indicate problems with the wiring or motors.
* Problems with the engine management system can result in reduced engine performance, fuel consumption problems, or even engine failure.
Precautions when working on the electrical system:
* Disconnect the battery before carrying out any electrical work.
* Only use fuses with rated power.
* Make sure all connections are secure.
