So yes, we nearly know nothing about the starter solenoid that most people want to know. But not anymore! We made this guide for you, to help you know more about the starter solenoid. From what is it, to how to wire it, from how to replace it to how to repair it by yourself. Trust me, this is the best starter solenoid guide online. A starter solenoid is a combination of solenoid and switches Full name: Starter Solenoid Switch. As we all know, the starting of the engine requires external support, and the car starter is playing this role.

A starter solenoid is an electromagnetic switch that produces a magnetic field to connect and disconnect the battery to the starter motor assembly. The solenoid works on the principle of electromagnetism. It has three terminals or connections on the back of the solenoid cap. If you want to know the starter solenoid wiring diagram in simple words. This page explains very easily. On this powerful page, you will learn the solenoid wiring, especially the 3 pole wiring schematic for the starter solenoid in understandable language, so that you know what wires go to the starter solenoid. Numerous individuals frequently encounter confusion distinguishing the starter motor from the starter solenoid. The starter comprises pivotal components: a robust starter motor assembly and a strategically positioned solenoid. The starter motor assembly, a substantial cylindrical unit, serves as the powerhouse for engine cranking. In contrast, the solenoid, a compact cylindrical component situated atop the starter motor assembly, plays a decisive role in establishing and disrupting the electrical linkage connecting the starter motor assembly to the battery.

So, the magnetic field coil and the armature coil can get the electric current directly from the battery. Jan 14, jac mac. Terminal B and Terminal M are usually copper bolts with a thickness of 8mm or 10mm, the one with lug plate is terminal M, which is the power supply terminal of the motor field winding; the other one is terminal 8, which is the power line terminal of the car battery. Replies 22 Views 2K. Thus, the plunger is pulled back by the return spring force , and the contact plate is disconnected, the starter stops. Drive the starter pinion engaging in the flywheel ring gear. Also, the starter solenoid is not energized, and the drive gear is separated from the flywheel ring gear. Replies 18 Views 3K. Replies 2 Views 1K. The whole process of starter solenoid switch can be divided into 3 stages: Sucking, holding, return.

This is how a 4-pole starter solenoid switch is connected. One of the larger terminals is connected to the hot wire coming from the battery, the second large terminal is connected to the starter, the first smaller terminal S connects to the ignition switch, the second small terminal connects to either ballast resistor R or ignition coil I and is generally unused.

After switching on the starter, the starter solenoid makes the clicking noise, slightly moves but does not rotate. JavaScript is disabled. Pinion gear. Save my name, email, and website in this browser for the next time I comment. Facebook Linkedin. As shown in the following picture. Disengage the outer lead of the starter field winding Terminal C, see Fig. The movable iron core should be able to move smoothly. Sean S. Search forums. Simply connect the battery terminal anode and terminal B of the starter by a lead wire. Firstly turn on the switch, gradually increase the voltage, when the multimeter resistance scale indicates a resistance of zero, the indicated value of voltmeter V is the pull-in voltage of the switch. The location of the starter motor can be differed by car models, the following instruction is the regular way to replace a starter solenoid.
