When you buy a car, you do not own a car but actually you owe a car, your "baby" needs to be pampered same way as your child. Each and every part or system must be taken care of either by repairing it or replacing it and the top of it is to know the pros and cons of every parts or system. One such important system is the electrical system of your Toyota Land Cruiser. Ah…actually the electrical system is not specific to any Toyota car model but is similar for all of them. Toyota Avalon, Toyota Crown, Toyota Tercel, Toyota Paseo…all of them runs on electric system.
Toyota's electric system comprises a storage battery, alternator, starting motor, lighting system, ignition system, controls and other accessories. Of all, alternator is a vital component of an electric system of your Toyota.
What is a Toyota Alternator?
A Toyota alternator is that vital part which delivers power to charge the electric battery and let all of your power hungry components to work together for the generation of a precised voltage and amperage. The major power hungry components are a rotating magnet or a rotor, an iron core or a stator, a set of rectifiers or a diode bridge, slip rings and brushes, and a small pulley.
Symptoms of a faulty Toyota Alternator
- Toyota car's light will badly lit.
- A large grinding sound can be heard may be because of a failed bearing inside your alternator.
- If not a single component is working and if you feel that your luxury is stalling then it's probably a bad alternator.
- Irrespective of the age of your Toyota battery i.e. its work tenure, it may become dead because of a faulty alternator. Before assuming that its dead never forget to check the connectors. In case if a connector has lost its footing over the battery terminal, then it may result into a bad connection hence no power supply through the circuit.
- Alluviation of dirt or corrosion around the battery terminal may also result into a bad battery connection.
Easy to do diagnostic test for your Toyota Alternator:
***Almost every vehicle on the road is a 12 volt DC (direct current) electrical system.
- Get a voltmeter, set it to DC and connect it your battery (red lead or wire to the positive terminal and the black to the negative).
- Switch-off everything that's electrical in your car, raise the RPM to 1,000.
- The voltmeter should register 14 volts; anything less than 12 is trouble.
- Now switch-on everything electrical including the headlamps, AC, radio, again raise the RPM to 1,000.
- Voltmeter should read 14 volts, anything which is significantly below 14 volts, signals a failing alternator.
Though it's difficult to find when an alternator may die or start malfunctioning for the reason that your Toyota may still run to few miles by consuming the stored power in your battery. So, to be on a safer side, it is suggested that you should check the tension in a drive belt of Toyota alternator whenever you are changing the oil.
