First of all, the whole car is unable to force
Cause Analysis:
1, battery electrical, ablation or internal disconnection;
2, the power is always opened;
3, the front packaging joint of the angle plate is loose, and the contact is poor;
4, the total switch solenoid valve is loose, contact difference;
5, battery pole line card is not tightening, loose, and poor contact;
6. The power supply switch is separated;
As shown in FIG.
EQ2102G side view
Method of exclusion:
1. Remove the battery cover and check if the battery has a test or multimeter battery. If there is electricity, check if the battery pole line is equipped with correct, reliable, reliable, when the battery is a positive and negative column, due to circuit short circuit, generator diode will be decomposed, need to be corrected immediately;
2, if the battery is powered, please check if the power switch solenoid valve is loose, the contact is poor, if the iron is not good, you should remove the iron wire, pull the paint on the frame. iron wire;
3. Check if the cab harness and the frame harness joint are loose, the contact is poor, if it should be corrected;
4. Check if the power switch is damaged or the head head is falling off. If this phenomenon is present, it should be corrected;
5. If the above inspection method is not excluded, the vehicle is in powerless failure, then the power supply switching solenoid valve is required to replace the total power switch solenoid valve.

Second, the starter does not work
Cause Analysis:
1, starting insurance;
As shown in Figure 2, the circuit components within the ignition lock are faulty;
3. Adverse contact in front of the cab;
4, start relay is bad;
5, the starter is damaged.

Method of exclusion:
1. Check if the starting insurance burns, if burned, need to replace the fuse;
2. A screw the ignition lock to the start, use the test lamp to measure whether the starting line on the ignition lock is electrified, if no electricity, the ignition lock internal component has a circuit breaker, and needs to be replaced. If there is electricity, you should check if the ignition lock is unobstructed. If it is not available, it will indicate that the fuse box bunch contact is poor;
3 Description of start relays;
4, if the starter relays are good, the magnetic switch on the starter also has electricity, still unable to start the starter, indicating that the starter is damaged.
