Technical Service Bulletin for 发电机常见故障诊断(一) 439540 - Valeo Service

发电机常见故障诊断(一)

<p><strong>发电机不发电诊断流程</strong></p>

<div>•确认发动机工况：怠速，中等转速和高转速。</div>

<div>•确认用电负荷：低负荷（怠速无空调和灯光），高负荷（打开大灯，空调制冷到最冷，发动机水温正常）</div>

<div>•确认蓄电池状态：使用蓄电池检测仪进行离线测量（把蓄电池与车辆线路断开）</div>

<div>•检查车辆充电警告灯。</div>

<div>•检查车辆故障代码（对于通讯故障，首先排除车辆型号匹配和其他故障干扰）。</div>

<div>•使用万用表测量蓄电池电压（发动机起动状态），电压在13.5-14.5V，极限状态不低于12.15V。</div>

<p>使用钳形电流表测量蓄电池充电和放电电流（电流参考发电机标签或者维修手册） 。</p>


客户反馈发电机不发电或者发电电压过高

发电机诊断流程

<div>•确认发动机转速：怠速，中速（2000转每分），高速（3500转每分）。</div>

<div>•使用万用表电压挡测量蓄电池两端电压。（电压在13.5-14.5V,极限状态不超过15V）</div>

<div>•使用钳形电流表测量蓄电池充电和放电电流（电流参考发电机标签或者维修手册）。</div>
