How are the circuits in the truck, from the battery to the key door to the starter, connected?

1.First of all, the negative pole of the battery is connected to the iron, and then the positive pole is connected to the large binding post of the starter, 2Starter large binding post connected to generator, 3

Starter large binding post power lock, 4Electric lock start relay, 5The starting relay is connected to the small binding post of the starter.

The steps are as follows: first the negative pole of the battery is connected to the iron, and then the positive pole is connected to the large binding post of the starter.

The starter is connected to the generator with a large binding post.

The large binding post of the starter is connected to the electric lock.

Electrically latching start relay.

The starting relay is connected to the small binding post of the starter.

Circuit: A conductive circuit composed of metal wires and electrical and electronic components, called an electrical circuit. Add a power supply to the input of the circuit to create a potential difference at the input terminal, and it can work when the circuit is connected.

The presence of current can be detected by some instruments, such as voltmeter or ammeter deflection, bulb light, etc.; According to the nature of the current flowing, it is generally divided into two types: the circuit through which direct current passes is called "DC circuit", and the circuit through which alternating current passes is called "alternating current circuit".

First, pull a live wire from the battery and connect it to the live wire of the starter. Then find the direct connection cable at the key door interface. The interface docking starter operation is a direct connection.

Separate the direct connection, pull one to the second line of fire of the starter, and the other to the first line of fire. If there is an inner iron in the starter. Just connect the wire to the bolt of the front cover of the starter on the iron, and the experiment will start the ignition.

The negative pole of the battery is connected to the iron. The positive pole is connected to the main fire line of the starter... Electrically lock the main live wire.

Which gear of the electric lock is generally connected to the starting relay. Then from the relay to the starter line of the starter. It depends on what car you have...

It just so happens that I'm repairing truck appliances. If you have any other questions, please contact 、、、

Hereinafter. The negative electrode of the battery is ironed.

The positive pole is connected to the large binding post of the starter.

The starter is connected to the generator with a large binding post.

The large binding post of the starter is connected to the electric lock.

Electrically latching start relay.

The starting relay is connected to the small binding post of the starter.

First of all, it depends on what kind of car it isThe negative electrode of the battery is ironed. 'The positive pole is connected to the starter suction switch, and the large wiring is attached'''The starter suction switch, the small wiring is connected to the starting relay'''The starting relay is connected to the electric lock.

1.Shouhe takes the negative pole of the battery first, and then the positive pole is connected to the large binding post of the starter, 2Starter large binding post hair extension Zen socks with motor, 3

Starter large binding post power lock, 4Electric lock start relay, 5The starting relay is connected to the starter and the binding post is good.

1. When the battery is out of power, first see whether the positive and negative electrodes of the battery are oxidized, and if there is oxidation, the terminal post should be sanded and cleaned with sandpaper, and then reconnected; Charge or replace the battery. Guess the Min battery is out of power, it may be caused by the generator not generating electricity, forgetting to turn off the light after stopping, after starting the engine to see if the lead Wang power generation indicator is Huai Zhaozai is extinguished, if not, it means that the generator is insufficient, the generator should be checked and repaired according to the situation.

2. Check the connection line and joint part of the battery and the starter, whether there is a loose connection, the fastening should be checked, and the sound of "answer" is generally that the starter magnetic switch is broken, which needs to replace the starter magnetic switch.

3. This situation is rare, the internal resistance of the engine is too large, and the starter cannot pull the engine.
