该测试测量冷却液开关两端的电压降。 测量测试点 (11) 和测试点 (7) 两端的电压降。 测试点 (11) 为正极触点而测试点 (7) 为负极触点。
电压降将导致冷却液指示灯点亮。 电压降必须大于 1.30 ± 0.15 伏。 灯点亮是了为说明有缺陷。
该故障可能的原因如下:
- 常开开关
- 带过高电压降的闭合开关
- 带焊接触点的开关
当发动机冷却液温度达到 38°C(100°F)时,冷却液开关断开。
该开关可阻止暖态发动机中起动辅助的使用。 暖态发动机中起动辅助的使用可能导致可能的损坏。
发动机冷却液必须低于温度 38°C(100°F),以使该测试有效。 必须先将暖态发动机冷却至温度 27°C(80°F),以闭合冷却液开关。
