"If exciter circuit fails your voltages won't be that good."

True, if something shorts D+ at the alt to ground.

The common instrument panel trouble causes an open circuit, which keeps it from being pre-excited when it starts up, but once it has begun charging properly, the open circuit will not affect the B+ voltage.
