19. Schematic electric circuits
General information
As it is impossible to provide in this manual all schematic diagrams for every year of release, the most typical schemes and those which are necessary most often are given below.
Before beginning troubleshooting in any chain, check safety locks and breakers of a chain (if they are) to make sure that they are whole. Make sure also that the battery is completely charged and check contacts of wires (see the Head Routine maintenance of the car). Checking a chain, make sure that all contacts are pure, plugs did not break off and were not disconnected.
