问：安装新交流发电机后，电池灯微弱地亮起

你好呀。您测试了电池吗？使用数字电池测试仪，可提供当前电压，冷机放大器和健康状况。终端上有腐蚀吗？这可能会给电动干扰带来机会并引起人们的关注。但是，这听起来确实像交流发电机或皮带有故障。检查适当的皮带张力和皮带状况，以确保其不滑。如果打滑，请根据需要进行调整/更换。如果检查确定，则交流发电机可能有故障。即使是新零件也可能是错误的，并且适当的负载测试将发现它是否确实有故障。 When you rev the engine, the alternator spins accordingly and can provide additional voltage/amperage which is probably why the light starts out dim and gets brighter when you do this. I suggest having a qualified technician perform an inspection to avoid replacing unnecessary parts. Your Mechanic has several available technicians that can assist you with a充电系统检查。
