Fist yes I searched cant find what im looking for/
I recently did a H/C/I swap on my 01 SS. I was careful to not break anything ir pinch any wires. start the car (brand new battery) idles but the gauge is about at 12. go drive it a bit now its about 10ish I stop to get gas fill up and click its dead. get a jump barely starts stumbling and sputters but I limp it home, fast forward to yesterday I go buy a new alternator start it up and its at 12 yet again, let is idle for a while never goes above 12. Go out this morning start it up volts are about 9 let it idle about 10 minutes hoping it goes up, nope so turn the car of wait 5 seconds try and start and click wont start Help please I checked the fuses in the car they're good brand new batt and new alt

 

there is a little wire connected to the alternator make sure its in all the way. it might be loose or the wire is damaged.
