| I have a 1994 Chevy Corsica with a 6 cylinder engine. In recent days a red
light that is shaped like a battery on the instrument panel has began coming
off and on intermittently. It comes on for a few seconds to a couple
minutes, then stays off for a while. When it comes on, my headlights get
very bright and my heater blower goes very fast. The battery is good. I took
a voltmeter and measured the voltage at the cigarette lighter socket. When
the battery-shaped indicator light is off and everything's normal it reads
14 volts. When the red battery-shaped light is on it reads 16 volts. The car
runs fine either way. This happens during both hot and cold operating
temperatures, light and full electrical load, and there doesn't seem to be a
pattern. I also hear a faint whining noise coming from somewhere when the
light is on. I thought the alternator was dirty so I sprayed it with a
garden hose and Joy dish soap, but that didn't change anything. I thought
about the voltage regulator, but can't find it. Does anyone know what is
going on here and if it's okay to continue driving the car? Thank you.
