I have a 1990 chevy silverado with a 5.7 v8 and every time I turn the blinkers on my alternator gauge pulses and when I turn on the heater the gauge drops and when I use the headlights I replaced the battery and alternator I can't figure it out

have the alternator re tested as it sounds like it is failing under a load.
