Ok so I have a 2014 Toyota Tundra SR5 I replaced the alternator and battery. But the volts were still jumping. So I replaced the alternator for the 2nd time and i am still getting the volts to jump and the guys at O’ Reilly’s just returned my money and told me to go to autozone if I wanted another alternator and mins you both alternator were remanufacture. So before I try for a 3rd alternator and a new one this time( haven’t bought it yet still thinking about it). I check the fuses and relays they seem good. Any ideas before I take it to the dealership.
