Most heavy trucks have one, two, or three cables going to the generator. Below we explain how to identify these wires and connect the alternator to your car. One wire: For generators with a positive lead connected to the alternator, ground is connected to the housing.
The three types of cables in a three-wire generator are the positive battery cable, the voltage sensor, and the ignition cable. The positive battery lead is connected to the starter motor. The voltage sensor cable is connected to the battery and the ignition cable from the alternator to the key switch.
- Terminal battery voltage sensor S.
- IG terminal Power switch that turns on the voltage regulator.
- Terminal L Close the hazard warning flashers circuit.
- Terminal B main generator terminal (connected to the battery)
- Full field bypass with F connector for controller.
This wire is connected to the battery directly or via a terminal in the main battery circuit. It usually connects to the battery side of the fuse block. Its purpose is to monitor the system voltage and increase or decrease the charging rate based on system load and / or battery condition.
Terminals R and F are the reference or voltage measurement terminal and terminal block.
The cable is connected to the L terminal of the generator. The power cord is used to turn on the voltage regulator. This cable, once disconnected, should be approximately 12.5 volts with the key inserted.
The two wires connected to the generators are the positive and negative wires. When connecting our generators, use Fig. 2 to connect these generators correctly. There is a jumper to connect the (S) terminal of the generator to the (B +) terminal.
A generator is a vehicle component that transfers energy from the power system to the battery for vehicle accessories such as radios, headlights, and air conditioning fans. A wire called an exciter creates the voltage needed to run a generator every time a vehicle is started.
The battery charging cable connects the main hub to the battery. In these systems, the battery charging cable only charges the battery, it does not supply electricity to the on-board network. On many other cars, the generator output lead goes directly to the battery (or the POSITIVE battery lead next to the starter solenoid).
You can confirm that it is a network by opening the case and looking for the letters SE on the voltage regulator. If it is already installed in the car, you will need to polarize it the first time for this to work. You only use a jumper to power port #. 1 or n. 2 on the side.

Number 1 or R or relay terminal.
The alternator is driven by a belt driven by the rotation of the engine. This belt rotates around a pulley attached to the front of the engine crankshaft and is typically responsible for driving a number of other components, including the water pump, power steering pump, and supercharger.

Fuses are installed to protect the wires from overload, which means that the air currents (amps) from the load (the device) exceed the capacity of the wire (gauge or meter). In these circumstances, a generator only needs a fuse if the battery or the alternator itself suffers a fatal short circuit.

Registered. Rule of thumb. When the motor turns clockwise, which it does, each pulley driven from inside the belt rotates clockwise and each pulley driven from the back of the belt rotates counterclockwise, like the water pump.
