A PDF diagram is not just for wiring; it’s a diagnostic map. Here are common errors the diagram can help you solve.
Before powering up, use a multimeter to check the resistance of the exciter field. It should match the manufacturer's specs (usually between 10 and 100 ohms). Initial Setup and Calibration
Wire F+ and F- to the exciter field. Polarity matters. Reverse polarity will cause the generator to build negative voltage or fail to build at all. The PDF indicates which color from the AVR goes to which exciter lead.
