Good advice, thank you. My Fluke doesn't show percent, but it supposedly does measure duty cycle. It was giving me a reading between 5.7 to 6.3 volts, which based on what I'm reading is between 57% and 63%? Not sure if that's accurate, but that's what I'm seeing. Does that mean it's running lean at idle?
