One side of the "idiot light" is wired to the coil side of the switch, regardless of whether the light is used to excite the #1 pin on a Delco alternator or simply as a "key on" light.
With a "key on" indicator the other side of the lamp would be grounded and the lamp would glow until switch is turned off or the bulb burns out.
