What it does

In a Ross Hill SCR house each engine-generator set runs its output through a control section that regulates excitation. The exciter PCB is the card in that loop: it takes the voltage regulator's demand and drives the exciter field accordingly. When it degrades, the symptom shows up at the generator, not at the card: voltage that will not build, drifts under load, or hunts.
