Warning: Before working on the electrical system, read the precautions given in Chapter 3 from this Section.
1. The electrical system is 12 volt negative ground and consists of a battery, alternator with integrated voltage regulator, starter motor and associated electrical wiring and components.
2. The battery is a maintenance-free type, charged by a generator that is driven by a belt from the crankshaft pulley. Starter - pre-engagement (with freewheel pre-engaged), has a built-in traction relay. When starting, the traction relay moves the pinion gear in engagement with the flywheel ring gear, and then supplies power to the starter motor. When the engine starts, the freewheel prevents the motor armature from rotating from the engine until the gear disengages from the flywheel.
3. When working on the electrical system, extra precautions must be taken to avoid damaging semiconductor devices (diodes and transistors), and avoid electric shock. Therefore, take into account the following points
4. Always remove rings, watches, and other metal objects before working on the electrical system. Even with the battery disconnected, discharge may occur if the component is grounded through a metal object. This may cause electric shock or electric burn.
5. Do not reverse the battery connections. Components such as a generator or others that have a semiconductor circuit part may be damaged.
6. When starting the engine with heavy gauge wires and an extra battery, connect the batteries positive to positive and negative to negative. This also applies when connecting the charger.
7. Never disconnect the battery terminals or the alternator plug while the engine is running.
8. Before electric welding on a car, it is necessary to disconnect the battery and alternator wiring.
9. Never use an ohmmeter with a hand generator to test circuits.
