Dongfeng off-road vehicle Electrical equipment Public Fault and Exclude-EQ2082E6D, EQ2100E6D circuit FAQ and exclude (1)

Dongfeng off-road vehicle Electrical equipment public fault and Exclude-EQ2082E6D, EQ2100E6D circuit often fail and exclude

First of all, the whole car is unable to force

Cause Analysis:

1. The battery is electrically unobstructed, short circuit or battery is disconnected.

2, the electromagnetic power supply is always open;

3, the current watch is being shed;

4, easy to volume linear or drop;

5, the wire joint on the total switch of the electromagnetic power source is loose, and the contact is poor;

6. The cab's indoor power is always closed or the wire falls.

Method of exclusion:

1. First, check if the collision line connector on the total switch of the electromagnetic power source is loose, no matter whether it is good, if the iron is not good,

Should be removed from the iron wire and placed the coating on the frame, then install the iron wire;

2. Check if the wire on the electromagnetic power source switch has electricity. If there is no electricity, the battery is faulty or the battery is not powered.

Exhaust, remove the battery cover, check if the battery is electricity, if there is electricity, please pay attention to check the battery

Whether the rod assembly is safe and reliable. If the load negative electrode, the generator diode must be destroyed, and the generator is required to be corrected immediately;

3. Check if the easy melting of the cab's electrical box is burned or fall off. If there is, it will be corrected;

4. Check if the line of the current table on the dashboard is turned off, if there is, it will be corrected;

5. Check if the power switch is damaged or if there is such a phenomenon, it will be corrected.

6. If the above inspection method is not excluded, the whole car is in powerless failure still exists, and then check the power supply total switch solenoid valve.

Whether there is a fault, if there is, the electromagnetic power switch should be replaced.

Second, the engine does not work (analysis and circuit of the circuit):

1. Ignition lock is closed;

2, the start relay is bad;

3, the starter is very bad. Method of exclusion:

1. Check if the \"ignition lock \" tab is dropped. If there is, it will be corrected;

2, unfold ignition lock to the start, measure whether the entry line on the starter relay is launched with the test light, if not, then

Start relays are bad;

3. If the starter is available, the magnetic switch on the starter is electrically conductive, but the starter cannot be activated, indicating the starter damage.
