how does an electric solenoid valve work

Manufacturing and water treatment plants make good use of hydraulic solenoids. Sometimes, they're not - and need to be replaced. Or perhaps your starter solenoid's the real culprit here.Īny mechanic should be able to give your solenoid a test if (s)he's got a circuit tester or multimeter handy. The culprit might be a dead battery or a compromised alternator. Instead, you hear an unpleasant clicking noise.

Has this ever happened to you? You're sitting in your car and just turned the ignition key, but the engine won't start. At least that's how it's supposed to work. Within a couple of seconds, your once-dormant car engine comes alive. And a 'pinion' gear wheel engages with a disc called the 'flywheel.' The circuit between the starter motor and the car's battery is completed. Electric current in the solenoid wire attracts a movable iron rod. Once it's activated, several things happen. Turning the ignition key relays electricity from your battery into a starter solenoid. Solenoids allow us to magnetize wires and then demagnetize them whenever we like (pretty much). Basically, we can have our cake and eat it, too.
