    • The system and method for determining the operational condition of an electric fuel pump (16). The test apparatus (22) is configured to perform first, second and third tests. During the first test, a low voltage, low current signal is applied to produce an inductive reflectance from the pump armature winding. During the second test, continuity is assessed in the coil winding circuit. During the third test, a higher power, short duration pulse is applied to create rotational movement of the pump armature for the purpose of detecting mechanical and/or electrical issues not otherwise discerned from the prior tests. An optional fourth test may be conducted in which the pump (16) is run for a short period of time at standard operating power to generate a current waveform. Collected test data is compared to stored reference data sets using a processor contained within the test apparatus (22). If collected test data corresponds within an acceptable threshold range to the reference data, a PASS signal is generated.
    • 用于确定电动燃料泵(16)的操作状态的系统和方法。 测试装置(22)被配置为执行第一,第二和第三测试。 在第一次测试期间,施加低电压,低电流信号以产生来自泵电枢绕组的电感反射。 在第二次测试期间,在线圈绕组电路中评估连续性。 在第三次测试期间,施加更高功率,短持续时间的脉冲以产生泵电枢的旋转运动,用于检测以前的测试中未另外识别的机械和/或电气问题。 可以进行可选的第四测试,其中泵(16)在标准工作功率下运行短时间以产生电流波形。 使用包含在测试装置(22)内的处理器将收集的测试数据与存储的参考数据集进行比较。 如果收集的测试数据对应于参考数据的可接受阈值范围内,则产生PASS信号。
