In this way, how does a turn signal circuit work?
How Car Turn Signals Work. Turnsignalsrequire electrical power in order to illuminate theturnsignal light bulbs. When the turn signal leverisactivated in either direction, a circuit is completedthatallows power to flow to the front and rear turnsignallights on the selected side.
Also asked, how does a 3 pin flasher relay work?
- Power Demands. A flasher relay is powered off oftheautomobile's 12-volt DC main. It is grounded (positive ornegativeground) to match the rest of the car's electricalsystem.
- Relay. The heart of the flasher is the relay.
- Flasher. The flasher is a thermostatic switch designed topoweron and off at a set rate.
Late model vehicles use an electronic flasherwithno mechanical parts. The flasher measure the amountofcurrent flowing to the turn signal bulbs. If thecurrentdraw is in the expected range, a solid state timingmechanism and atransistor turn power on and off to the turnsignalbulbs.
