HOW TO know if you alternator is bad
Hey guys, so we got this Audi TT as our next build project and we noticed that something was not right. It definitely needed new alternator. Check out the video to see how we came to the conclusion that the Audi needs new alternator. Always check the alternator fuse. Check the voltage of the battery with the car running (keep your hands away from moving parts). Check wires and read OBD Codes before wasting money on new alternator.
