basis. While most testing is done to ensure soundness of the engine, it is significant to examine the battery, ignition and on-board systems as well. Failure of any of these critical components leads to a complete vehicle breakdown and loss of valuable time and money.
Increasing complexity in automotive systems leads to rising demand for electrical power. In turn, this leads to greater demands on the battery of the vehicle. Regardless of the automobile being electric or dependent on an internal combustion engine, ensuring battery reliability is of utmost importance. This requires regular monitoring of battery diagnostics while the automobile is running.
Since a battery discharges even when not in active use, its health deteriorates over time. Battery diagnostics helps in identifying a depleted or faulty battery, thus avoiding a system breakdown.
The latest approach to conducting battery diagnostics is measuring its state of charge in terms of current-delivery capacity and its state of health in terms of the remaining percentage of battery life while the vehicle, with its various electrical loads, is in operation.
A timing light is used to set the ignition timing of a vehicle. When it is attached to the ignition circuit while the engine is running, it identifies timing marks, thus enabling setting the timing of the ignition system.
