What does your voltage gauge do while all this is going on?

Is this a plug and play? Any other parts needed?

alternators are plug and play. I'm getting mine rebuilt now. Remove back screw first. Then loosen the front 3 bolts. slide the alternater and pulley bracket forward about an inch. Use Left hand to feel for the clip. R hand with small screw driver to flip the lip off the red wire plug. pull alternater and pulley off. Takes 20 min. Reverse order and drive away.

Have the exact same issue on my 02 35th, but the voltage gauge doesnt move from past 13 volts...if you give it a little gas...it flickers bad...
Any thoughts on my particular issue...
Just got the car in January
