mover and input power supplies before installing or servicing voltage
regulator. Use a voltmeter to verify that power is off before contacting
conductors.

the generator shaft is rotating. Shaft rotation produces voltage in
generators even when no excitation is applied. Residual voltage is
present at the generator leads and regulator connections even when
the regulator fuse is removed.
