Dongfeng off-road vehicle Electrical equipment common fault and exclude-EQ2082E6D, EQ2100E6D circuit often failure and exclude
First, the whole car is powerless
Cause Analysis:
1. The battery is electrically powerless, shorted or the battery is broken.
2, electromagnetic power supply is always open;
3, the current watch is falling off;
4, easy-flux linear or falling off;
5, the iron wire joint on the total switch of the electromagnetic power source is loose, and the contact is poor;
6. Cab indoor power supply has always turned down or the wire is falling off.

Method of exclusion:
1. First, check whether the collision line joint on the total switch of the electromagnetic power source is loose, whether it is good, if the iron is not good,
Should be removed from the iron line and put the paint on the frame and then install the iron line;
2. Check whether the wire on the total switch of the electromagnetic power source has electricity. If no electricity, the battery is faulty or the battery is not electricity.
Exhaust, remove the battery cover, check if the battery is electricity, if there is electricity, pay attention to check the battery
Whether the pole line assembly is secure and reliable. If the negative electrode is loaded, the generator diode must be broken, and the generator is required to be corrected immediately;
3. Check if the easy-to-fusement of the cab electrical box is burnt or fall off. If there is, it will be corrected;
4. Check whether the line of the current table on the dashboard is off, if there is, it will be corrected;
5. Check if the power switch is damaged or if there is such a phenomenon, if there is this phenomenon, it will be corrected.
6. If the above-mentioned inspection methods have been excluded, the full vehicle powerless fault still exists, then check the power supply total switch solenoid valve.
Is there a malfunction, if there is, the electromagnetic power source switch should be replaced.

Second, the engine does not work (the reason for the analysis and circuitry):
1. The ignition lock is off;
2, the starter relay is bad;
3, the starter is bad. Method of exclusion:
1. Check if the ignition lock tab is falling off. If there is, it will be corrected;
2, screw the ignition lock to the startup, measure whether the starter line on the starter relay is fired with the test light, if not, then
The starter relay is bad;
3, if the starter relay is available, the magnetic switch on the starter is electrically, but it cannot start the starter, indicating the starter damage.
