Bad electronic smellīad connection when it comes to electronics creates heat. Therefore, if you are looking at a battery that had died when working the day perfectly before, the ignition relay could have been the cause. This means the circuit will not open after you remove the key, and the battery will drain. When the ignition relay fails, it can cause the ignition system to be activated constantly, even when you have removed the keys from the ignition. When you switch off the ignition key, the ignition relay should also shut off power to all engine components otherwise, it will drain the car battery when you let the car stands over the night. This can cause the connection area inside the relay to become too small – which will cause the ignition to shut off and on super fast. Situations occur when there becomes corrosion inside of the ignition relay. If your dashboard is blinking like a table-flipping game, there may be an issue with the ignition relay. If your car shuts off while driving, the ignition relay can be to blame. Without these components, your engine will die imminently, so you can probably guess what will happen if it can’t deliver power to them. The ignition relay supplies power to essential engine parts like the fuel pump and the ignition coils. RELATED: Symptoms of a Bad Fuel Pump Relay & Location 2.
