The volt gauge normally reads 15 volts. When I run the lights & heater fan, its drops to 9 volts. I hear a whistling noise that appears to be coming from the alternator. It returns to 15 volts when I shut them off. Also, the battery seems to be slowly discharging. Could this be a problem with the alternator?
