3 Pin Flasher Relay Circuit

The flasher receives power from one of 2 fuses depending on whether or not the hazard switch is operated.

3 pin flasher relay circuit. Current flows through the resistive wire heating up. When you push the turn signal stalk down the thermal flasher connects to the turn signal bulbs by way of the turn signal switch. Clip the test light lead between the p terminal and the negative terminal of the battery. The heart of the flasher is the relay.

One is operated by a piece of wire or a bimetallic strip which expands and contracts as it is heated by the current. Connect the b terminal to. Initially the spring steel does not touch the contact so the only thing that draws power is the resistor. Each part should be set and connected with different parts in specific manner.

The relay is the electromechanical device that makes the operator. How does a three pin flasher relay work. The other is a relay operated by a transistorised circuit. The repetition rate or the flashing rate from this design is practically independent of the supply voltage ambient temperature or the load number of lamps connected.
