Ive been having major fluxuation in my battery gauge even with a 130 amp alternator in. I can barely turn on the radio,windshield wipers and the lights without it being near the red. Also after 45 mins of driving around the gauge reads my battery is real low and the needle is near the red. What could be the problem?

Is it a new alternator? If not unhook the battery when the car is running if it dies you need an new alternator.

Brand new ones can be bad/malfunctioning also. Trust me I know.

Check your ground wires to frame/block.

You can get the alternator tested to make sure it is charging properly.
