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 swap. When the ignition swap is turned, {the electrical} sign flows by means of the solenoid, which causes an electromagnet to drag 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 might fail over time, so it is very important know how one can set up a brand new one if wanted.
Starter solenoids are available a wide range of sorts and sizes, relying on the applying. The most typical kind of starter solenoid is the pre-engaged solenoid, which engages the starter motor with the flywheel earlier than the starter motor is activated. This sort of solenoid is usually used on automobiles with guide transmissions. Different varieties 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 automobiles with computerized transmissions.
