The lamp gets ground from the "I" wire only, and only when the alternator charges.
Incorrect, which is why your ign. switch idea is incorrect. As put by Peter Federick "The alternator light is the "indicator" in a voltage balance circuit -- it says there is current flowing through the alternator winding, not "balanced" by output. The circuit is usually not directional, so current flow from the battery to the alternator will cause it to come on (not chargine), but so will current flow from a short." It's def'n the alternator.
