ford f150 voltage jumprs on dash gauge
When the battery voltage gauge of Ford F150 instrument panel is lower than the working conditions of the controller and needs to supplement the power, the system will display "undervoltage". Generally , it can be charged immediately . This is a protective device designed to prevent the battery from over discharging. The battery cannot be over discharged.
If a fully discharged battery is charged again, it will reduce 5-10% of the total capacity. Therefore , the electric vehicle should be equipped with a protection circuit against over discharging.Classification by battery voltage gauge: the undervoltage protection value of 36V electric vehicle is 31.5v , and the undervoltage protection value of 48V is 42V undervoltage protection , which means that if the vehicle voltage is lower than the protection value , the controller will stop working to prevent over discharge of the battery .
The original design of single grid 5-piece and 6-Piece system can be changed to 6-Piece and 7-piece system, 7-piece and 8-piece and 9-piece system. The battery capacity can be improved by reducing the thickness of the plate and the separator and increasing the number of plates. Increase the amount and proportion of lead oxide, the active material of the positive plate.
From the appearance , the ford f150 dash gauge voltage jumper is a small metal rod (jumper post) embedded in the motherboard , sound card , hard disk and other equipment , as well as a small clip (jumper clip) sleeved on these metal rods. The function of jumper is to adjust the on-off relationship of different electrical signals on the equipment , so as to adjust the working state of the equipment , such as determining the main board voltage , the master-slave relationship of the driver, etc . When the jumper clip is sleeved with two jumper posts at the same time, it indicates that the two jumper posts are connected. If only one or no jumper is sleeved, it indicates that it is disconnected. It is very important to adjust the jumper . If you jump wrong, it will crash slightly and even burn the whole equipment seriously. Therefore , when adjusting the jumper , you must carefully read the manual and check the jumper name , jumper column number and on-off relationship.
