1.Product Introduction

The most common causes of damage to the computer board of the excavator are water inflow and mechanical impact. In addition, lightning stroke, welding surge, pin corrosion, internal component ablation, etc. will also cause damage to the computer board. The usual way to prevent welding surge is to disconnect the power supply of the whole machine, that is, to cut off the battery switch. Some manufacturers even require users to disconnect the computer board from the machine harness before using electric welding. The most common cause of pin corrosion is the poor sealing performance of the large plug of the computer board, which leads to water immersion, and eventually leads to pin breakage or poor contact.
