What are the reasons and solutions for the failure of the fuel gauge of diesel forklift trucks?
Forklift fuel gauge failure is common in internal combustion forklifts that have been used for a certain number of years. Years of sun and rain have caused forklift sensors to malfunction!
1. Forklift fuel gauge oil needle cannot moveNo matter how much gasoline is added, the fuel gauge will always read "0", or the forklift needle does not move when the ignition is turned on. The reasons are: the fuel gauge power cord or the sensor between the fuel gauge and the wiring iron; the welded joint of the coil is disconnected, poorly connected or burned, causing the circuit to not work; the fuel gauge after wiring is reversed.
2. Forklift fuel gauge counts inaccurateIt may be the reason of the loose wiring, or the fault of poor grounding or poor sensor resistance. First, check the wiring and grounding, and then use the component exchange and comparison method to judge whether the old part is faulty, so as to determine whether to repair or replace it.
3. Forklift fuel gauge counts higher than normalThe fuel gauge always reads "1" or high, regardless of the amount of oil. The reason is that the sliding piece of the sensor is broken by the wire, and the contact between the sliding piece and the variable resistor is interrupted. In the above case, the resistance of the line will be large regardless of the position of the float, similar to the situation where the float is rising and the variable resistor is connected to the line, so the reading is always "1" or higher.
