I'll be connecting 5 wires to the solenoid. Have you encountered a similar issue? Here's a schematic to assist you. The two huge eyelets are connected to the upper large lug. The single little wire will be connected to the solenoid's smaller eyelet on the right side. If you're staring at it right now, here's a diagram to assist. The two big black wires go to the upper large lug on the left side. The one little white wire goes to the solenoid's smaller eyelet on the right side.
Hope this helps!
The red wire connects to the starting solenoid's battery (large) terminal. The purple wire connects to the solenoid's "S" terminal. The yellow wire connects to the solenoid's "R" terminal. All three wires must be connected for the starter to work.
When you turn the key to start your car, the computer sends a signal through the red wire to the starter, which engages the engine and turns the keyless-entry remote transmitter activated. As long as all three wires are connected, the starter will keep running until you shut off the power by pressing the brake pedal or turning off the ignition switch. If you leave the red wire connected but remove the keychain remote, the starter will still run because it receives power from the battery through the white wire.
In addition to connecting the red wire to the battery, many owners also connect the black wire to the battery. This is necessary when using an auxiliary electric fuel pump or any other accessory that draws power directly from the battery. If the black wire is not connected then the pump will not operate when you turn the key to the ON position.
Finally, some owners connect both terminals of the battery ground connector to the chassis of the car. This is recommended by most battery manufacturers as an extra safety measure to prevent someone else from getting a shock if they touch one of these wires.
A starter-mounted solenoid typically has three terminals and three connections: The "B" terminal, sometimes known as the "battery" terminal: The connector that links the solenoid to the positive battery cable directly. The terminal labeled "S" or "start" receives electricity from the ignition switch. The third terminal is usually bare copper but may have some form of protective coating.
Starters are used in engines without electric fans or power steering to provide auxiliary electrical power when the engine is not running. They are also used when installing new batteries because there is no need to connect the negative side of the old battery to the vehicle's metal body when replacing it with a new one. This prevents shorting out these negative plates. Instead, all you have to do is connect the "B" terminal of the starter to the "B" terminal of the new battery, and the vehicle will be ready to go again!
Some vehicles use an electronic control unit (ECU) instead of a mechanical starter. These units are much less prone to failure than their mechanical counterparts and require little maintenance. They can also start vehicles with weak batteries or after they have been disconnected for some time. On these types of starters, the B terminal would be connected directly to the positive battery cable and the S terminal would be left blank. Mechanical starters are still used in conjunction with ECUs to provide backup power in case something goes wrong with the electronics.
Solenoid for the starter. A typical starting solenoid has one small connection for the starter control wire (shown in white) and two big terminals: one for the positive battery cable and the other for the thick wire that powers the starter motor itself (see the diagram below). The terminal for the positive cable is normally marked "START".
The connector on the starter solenoid may be different from the one shown here; check the manual for your vehicle's starter system for complete details.
Starter circuits are now usually powered by electricity instead of a spinning metal disk called a "disk starter". Modern starters use electric motors that are controlled by electronic modules called "starter switches". These units are located near the battery and monitor the voltage between the battery and the starter motor. When power is applied, the starter switch closes the circuit and allows current to flow through the starter motor and gearbox. This turns the motor which then turns the gearbox, which finally turns the wheels via a differential mechanism.
When you turn the key to start your car, you are actually engaging the starter relay which connects the battery to the starter circuit. The starter relay may be labeled "KEY ON", "ACC", "AIR BAG", "HORN", "AUDIO", or something similar. It should be located inside the passenger compartment under the hood or behind the dashboard next to the ignition switch.
However, if the starting solenoid is independent, you'll have an extra set of connections. The starting cable links the starter to the solenoid, and the battery cable connects the solenoid to the battery in that scenario. In any scenario, the negative connections serve as ground wires to the chassis. The positive connection serves as a power source for the starter motor.
In addition to these connections, there are three more cables that must be attached or connected to the vehicle's electrical system for the engine to start. These are the brake light cable, the fuel line cable, and the ignition key cable.
The purpose of the brake light cable is two-fold. First, it allows the starter motor to work when the brakes are applied. If the cable is not present, then no lights will come on when you push down on the accelerator pedal. This can cause confusion during morning rush hour traffic when your car is acting like it has no issue getting started.
The second purpose of the brake light cable is to provide power to the head lamps when the engine is running. If this cable is not present, then the headlights will not come on when you turn the steering wheel slightly left or right. Again, this can cause confusion during morning rush hour traffic when you need to make a right turn out of a parking lot or garage entrance and cannot see what's beyond the edge of the space.
Installation of a Battery Cable on the Starter In a nutshell, the red cable connection clamps onto the positive terminal and the black cable connector clamps onto the negative terminal. This is true regardless of whether you are changing the battery or the starter. If you need help with this task, feel free to call us at 888-209-0907.
These questions are often asked by new drivers: What does a dead battery mean? How will knowing this help me fix my car? And most importantly: Where do the cables go on a dead battery?
If your car's battery is dead, this means that there is no electrical power going into the battery nor coming out of it. Most likely, the battery is unable to deliver any charge to the other components of the vehicle through its cables, so they will not work. In order to determine if the battery is actually dead or just in need of replacement, we will need to look at some basic information about your car. Some vehicles have batteries that are located under the hood while others have them in the trunk. Regardless of where the battery is located, all it takes to check if it is alive or not is to turn off the ignition switch, which should disconnect the circuit connecting the battery to the rest of the engine. If the battery is dead, it will be impossible for it to provide electricity when you turn the key to the ON position.
