Introduction to Starter Solenoids
Starter solenoids are electromechanical gadgets which might be used to have interaction the starter motor with the engine’s flywheel. They’re sometimes mounted on the starter motor itself and are activated by {an electrical} sign from the ignition change. When the ignition change is turned, {the electrical} sign flows by means of the solenoid, which causes an electromagnet to tug in a plunger. The plunger then engages a gear on the starter motor with a gear on the flywheel, which begins the engine. Starter solenoids are an integral part of the beginning system and may fail over time, so you will need to know the right way to set up a brand new one if wanted.
Starter solenoids are available in quite a lot of sorts and sizes, relying on the applying. The commonest kind of starter solenoid is the pre-engaged solenoid, which engages the starter motor with the flywheel earlier than the starter motor is activated. The sort of solenoid is usually used on autos with guide transmissions. Different kinds of starter solenoids embrace the overrunning clutch solenoid, which permits the starter motor to proceed to spin after the engine has began, and the solenoid shift solenoid, which is used to have interaction the starter motor with the flywheel on autos with computerized transmissions.
