There is a RPM that the exciter circuit has to see before the alternator supplies a charge. Below this RPM, there is no charge.
I have a GM 1 wire 160amp alt and have to be above 1200 RPM to charge. If your volt gauge is working, you will see it drop below 14v at idle and jump up with the exciter RPM.
If the batt connection was loose, you would see the fluctuance in the headlights when you come to idle and brighter with RPM.
