Analysis of Lighting Circuit Problems in Excavator Circuit System Malfunctions

What is the biggest fear when buying an excavator? Of course, it is the various constantly emerging fault problems, although the excavator circuit system and computer can now provide a large part of fault prompts. However, some faults involve a wide range of issues, especially the two most headache inducing problems of the excavator's circuit system and oil system.

Here, Huacheng Second hand Excavator mainly discusses some common problems in the circuit system and how to easily troubleshoot them. Resolve the fault as quickly as possible.

The lighting system is the simplest circuit problem for excavators. When there is a malfunction in the lighting system, the first thing to distinguish is whether it is a problem with the light source. If the light source problem is ruled out, it may be due to a damaged high-voltage fuse. In this way, simply replacing the blown fuse can solve the problem easily. If the lighting system of the excavator flashes, circuit fault detection is required. Some common lead-acid batteries can also cause circuit faults, especially when checking for oxidation or electrolyte leakage in the battery connection. If the battery problem is severe, it is recommended to replace it in a timely manner.

The internal faults of the battery are mainly reflected in the sulfurization of the electrode plates, the detachment of the active material from the electrode plates, the short circuit of the electrode plates, and the reduction of the faulty electrolyte. When maintaining the battery, checking the electrolyte density and liquid level, and ensuring proper charging can effectively avoid the above situation.
