Wiring diagrams - General information



Since the inclusion of this manual electric circuits corresponding to models of all years of release, it is not possible, in this section is collected and presented only the most typical of the schemes that require frequent access them.

Before you start troubleshooting electrical circuits check the condition of the fuses and circuit breakers (if any), as it is their burnout may be the reason of failure of the circuit. Make sure the battery is fully charged, and the tips of the wires are securely connected to its terminals (Head of Adjustment and routine maintenance).

During the test, make sure to clean all contacts, make sure that the terminals are not appeared broken off, and their attachment weakened. When disconnecting electrical connectors, never pull the wires - always pull the plug housing.

The table below shows a map of color-coded wires, taken on the cars of this brand.
