A solenoid is a coil of insulated wire wound around an iron or steel rod. Its job in your car is mainly to transmit electrical current from the battery to the starter. If it is broken, power will stop flowing from the battery, and the circuit will fail. As a result, your vehicle won’t start, even when you jump it or change the battery. You may also hear a clicking noise as you try to turn the key.

If you think your solenoid may be faulty, you should visit a professional mechanic to do some testing, as inexperience handling solenoids and their associated components can lead to shocks. A mechanic will try to bridge the connection between the battery and starter to allow power to flow. Voltage checks will also be conducted, since improper voltage can reduce the solenoid’s work output.

In addition to the starter, solenoids are also used to operate chokes, valves, throttle control levers, and clutches. Troubleshooting any problems in these areas will require different tests. First, the mechanic will scan for broken parts, a blown fuse, frayed wires, or loose connections. While a technician cranks the key switch, another will watch the solenoid and inspect the shutdown system. If the solenoid does not pull in, the mechanic will adjust the linkage assembly. If the solenoid is faulty and still causes your electrical system to misfire, you will be better off replacing the part.
