Part 1: Removing a Bad Starter
(1).Disconnect the battery.
You will not need to remove the positive cable on the battery.
Always disconnect the battery before servicing the electrical system in your vehicle.
(2).Jack up the vehicle if need be.
Ensure you jack the vehicle up on firm, level ground.
(3).Locate the starter.
The smaller cylinder attached to the starter is the starter solenoid.
A wire should run directly from the positive terminal on the battery or from the fuse box under the hood to the top terminal on the starter solenoid.
(4).Disconnect the wiring to the solenoid.
In some cases, it may just be clips you need to disconnect for the wiring.
On some starters, you will need to loosen bolts or screws that hold the wires in place.
(5).Remove the starter retaining bolts then the starter.
Be sure to use the correct size socket, otherwise you risk damaging the bolts.
(6).Compare the new starter to the old one. Slide the starter into place.
If the two starters don’t look mostly identical, it may not be the correct starter for your vehicle.
New starter solenoids often come with four terminals, but can be used with only two.
Fault Check:
The starter often has failures and phenomena that cannot rotate or rotate slowly. In this case, check the following aspects:
1. The battery has no electricity or the electricity is weak, so the starter cannot rotate or rotate slowly.
2. The starter thread is loose or off, and the switch or adsorption switch fails.
3. The brush is worn out or the brush surface is not correct, and the spring is weak, resulting in poor contact of the rectifier.
4. Excitation coil or armature coil is short-circuited or disconnected.
5. The rectifier is fouled and the mica sheet is protruding, causing poor contact between the brush and the rectifier.Organization maintenance
In the process of starting the engine, the starter must draw in 344~400Ah from the battery. Therefore, in order to prevent the battery from over-current or damage, the starting time should not exceed 5s. In winter, it is easy to start difficult to start. Multiple starting times should not be too long, and appropriate intervals should be left in each starting.
