Here is the answer from my 83 Owner's Manual: Page 9 Charge System Light An electronic low voltage indicator light circuit takes the place of a conventional ammeter. This circuit, with the light labeled VOLTS, actually monitors the charging system, rather than just the alternator. Activation of the light under heavy electric loads during idle, particularly in cold weather, is normal. The light should go out when the engine speed is increased. UNDER ANY CONDITION, IF THE INDICATOR LIGHT STAYS LIGHTED AT NORMAL OPEN ROAD DRIVING SPEEDS, THE DRIVER SHOULD HAVE THE VEHICLE ELECTRICAL SYSTEM SERVICED IMMEDIATELY. There you have it.
