Frequently Asked Questions (FAQs)
1. What relay stops car from starting?
The relay that stops a car from starting is the starter relay. It completes the electrical circuit and boosts the battery's current. If the starter relay is faulty, the electrical signal won't reach the starter motor, preventing the engine from turning over.
2. How does an ignition relay work?
An ignition relay acts as a circuit completer or breaker between the car's battery and the starter motor. It increases the battery's current, reducing the amount of current needed for ignition. This helps ensure efficient starting of the vehicle.
3. Will a car start without an ignition relay?
No, a car cannot start without an ignition relay. When the ignition key is turned or the start button is pressed, a large current is generated. The starter motor requires significant current, which cannot be controlled directly by the ignition switch. Without an ignition relay, the system would burn out and the vehicle would not start.
4. Can a bad ignition relay drain the battery?
Yes, a bad ignition relay can drain the car's battery. The ignition relay is responsible for ensuring that electricity flows from the battery to the different components that require power. If the relay is faulty, it may cause a drain on the battery and make it difficult to start the ignition.
