Tony, You have blown a regulator in the alternator. The light wire is the exciter wire for the regulator and 12 volts is going into the alternator thru the light( #161 No sub )or battery light on the dash. Then when the alternator starts turning it nullifies the light and it goes out. If the alternator is turning at a good idle and the light is on then the regulator is bad. You may also see the light come on when you run thru a water puddle and it goes off. This is a normal typical problem .

Suddenly I realized my battery light was dimly lit while driving. Not sure how long because I only drive it on bright sunny days and the light is hidden behind the steering wheel. It comes on brightly with the engine off and the ignition on as it should. However just barely glows at an idle and gets brighter as you rev the engine. I checked as many connections as I could get to - battery, relays, fuses etc. all are tight and no changes while jiggling the wires. A volt meter across the battery reads 13.5 while the engine is running so I'm not too worried because it's charging the battery. There are virtually no add-ons like alarms or radio etc. Any suggestions? The book points to Alternator or regulator. Oh, and the belt is tight.
