Troubleshooting method for electric equipment of automobile inspection equipment

Date of release:2018-06-07 Author: Click:

If the motor does not rotate, there may be breakers in the wiper line and switch, the fuse of the scraper circuit fuse, the damage of the motor and so on. The fault maintenance methods of the electrical equipment for the vehicle inspection equipment are as follows.


Troubleshooting of 1. scrubber not working


When the scrubber is not working, the first check line is broken off and the fuse is burned. If the line connection and the fuse are all normal, the scrubber motor plug is pulled out and the voltage of the plug power terminal is measured by the DC voltmeter or the 12V measuring pen when the scrubber switch is switched on. If the voltage is normal, it is necessary to overhaul or replace the motor of the scrubber; if there is no voltage, it is necessary to check or replace the scrubber switch.


If only the scrubber does not spray water, then the nozzle or water pipe is seriously blocked. It should be dredged and cleaned, and the washing liquid o should be replaced.


Low water pressure of 2. scrubber


If the nozzle of the scrubber is sprinkled with water, but the water spray pressure is obviously insufficient, the water pipe and the washing pump should be checked and dredged. If the spray force is still insufficient after the water line is dredged, the motor of the scrubber should be overhauled or replaced.


Troubleshooting of 3. scrubber intermittent work


The scrubber works and does not work at the time. This is usually caused by the circuit connection and the bad switch. The scrubber motor line connection and the scrubber switch should be checked first. If it is normal, it is necessary to clean the line of the scrubber, the washing pump, and replace the washing liquid.


4. troubleshooting of defrosting


When the defrosting device does not work, check whether the line is broken off or not, and whether the fuse is burned. If the circuit connection and fuse are normal, the defrost switch will be short circuited to see whether defrosting can defrost. If it is still not defrosting, it is necessary to use special 7: repair and defrost gate wire; if defrost can be done, it is necessary to repair or replace the defrosting switch.
