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.

Do you have any aftermarket toys on the vehicle - stereo, amplifiers, fog or off road lights, winch, etc?

No I do not have any of that.

Try cleaning your battery terminals and checking that your grounds are tight and corrosion free. The ground from the battery to the chassis and from the engine to the chassis are most important, but not the only suspects.
