Automotive Flasher Circuit Diagram

An automotive flasher circuit is a simple electronic circuit that is used to flash the turn signals on a vehicle. The circuit consists of a few basic components, including a flasher relay, a resistor, and a capacitor. The flasher relay is responsible for generating the high-voltage pulses that cause the turn signals to flash. The resistor limits the current flow through the circuit, and the capacitor stores energy that is used to power the turn signals when the flasher relay is not energized. The following is a diagram of a basic automotive flasher circuit: ``` [Image of a basic automotive flasher circuit] ``` The flasher relay is represented by the symbol with the two coils. The resistor is represented by the symbol with the zigzag line. The capacitor is represented by the symbol with the two parallel lines. The battery is represented by the symbol with the plus and minus signs. The turn signals are represented by the two light bulbs. The operation of the flasher circuit is as follows: 1. When the turn signal switch is turned on, the battery voltage is applied to the flasher relay. 2. The flasher relay energizes and closes its contacts. 3. The current flows through the resistor and the turn signals. 4. The turn signals light up. 5. The capacitor charges up. 6. The flasher relay opens its contacts. 7. The current stops flowing through the resistor and the turn signals. 8. The turn signals turn off. 9. The capacitor discharges. 10. The process repeats itself, causing the turn signals to flash. The speed at which the turn signals flash is determined by the value of the resistor and the capacitor. The higher the value of the resistor, the slower the turn signals will flash. The higher the value of the capacitor, the faster the turn signals will flash. Automotive flasher circuits are typically very reliable and can last for many years. However, they can occasionally fail. If the turn signals on your vehicle are not flashing properly, the flasher relay may be the culprit. You can test the flasher relay by replacing it with a known good one. ## Automotive Flasher Circuit Diagram Tutorial This tutorial will show you how to create an automotive flasher circuit diagram. We will be using the following components: * A 12V battery * A 12V flasher relay * A 100 ohm resistor * A 1000uF capacitor * Two 12V light bulbs

Step 1: Connect the battery to the flasher relay.

The positive terminal of the battery should be connected to the "86" terminal of the flasher relay. The negative terminal of the battery should be connected to the "30" terminal of the flasher relay.

Step 2: Connect the flasher relay to the resistor.

The "85" terminal of the flasher relay should be connected to the positive terminal of the resistor. The negative terminal of the resistor should be connected to the "87" terminal of the flasher relay.

Step 3: Connect the flasher relay to the capacitor.

The "87a" terminal of the flasher relay should be connected to the positive terminal of the capacitor. The negative terminal of the capacitor should be connected to ground.

Step 4: Connect the light bulbs to the flasher relay.

The positive terminal of each light bulb should be connected to the "30" terminal of the flasher relay. The negative terminal of each light bulb should be connected to ground.

Step 5: Test the circuit.

Turn on the switch and the light bulbs should flash. If the light bulbs do not flash, check the connections to make sure they are correct.

Troubleshooting Tips

If the light bulbs do not flash, here are some troubleshooting tips: * Make sure the battery is properly connected. * Make sure the flasher relay is properly connected. * Make sure the resistor is properly connected. * Make sure the capacitor is properly connected. * Make sure the light bulbs are properly connected. If you have checked all of the connections and the light bulbs still do not flash, the flasher relay may be defective. You can try replacing the flasher relay with a known good one.
