why does my voltmeter jump whenever i use my turn signals and my battery drains after being parked for a couple of days. Ive already replaced battery terminals battery and starter. Any ideas?
Have the alternator tested.
Yeah, it sounds like your alternator, or the voltage regulator inside of it is going bad.
To be honest i've had several cars that do that and nothing bad has happened. My current one did that before and after an alternator change and my dad's 94 chevy 3500 has been doing it for years. If anything the alternator has proven it's work due to my dad leaving interior lights on all the time and needing a jump.
