No power after switching alternator. 2008 Hummer H3 z 3.7 l
Put in a new alternator. Car was dying just stopped in the middle of driving it. Killing the battery which is only a couple mo this old
we had to jump it to move and and it started up with a jump however , once the new alternator is installed I can’t get a drop of power no ac lights nothing . Battery tests around 12 to 13 volts. Did some checking with multimeter and seems power makes it to the fuse box and out the fuse box and to the alternator yet there is. zero power and jumping does nothing.
key is stuck in ignition.
I think I need some help here. I have no idea what we missed. It was able to jump vendors the switch and now it’s deader than a doorknob
any advice or conclusions if anyone has experienced the same things It’s Stuck half way in my garage and I got to move it thanks ☺️

If you took apart the fuse block, that is your problem. Many people do not know how to properly put the block onto the wire harness connectors underneath, You have to snap each harnes into the bottom og the fuse block, then snap the fuse block with connected harnesses back down into the tray.
Re-check your wiring.

Just tried again
So silicone spray would be okay. I can try that. I just did it again. Thinking I had it in the bag I was vet careful. The problem I think is my helper broke one of the pins on on of the cases and it’s making it more difficult the plastic pice that clips to hold it up. I’ll try some silicone. Would there be any other reason it wouldn’t start at this point. ??

Take a look at this old thread, it might help you understand that getting the fuse block and harness connectors is a highly focused task............ No Power, new battery, stuck key
Like I said before, you need to get all the connections to the underside of the fuse block in place and spot on BEFORE you attempt to snap the fuse block back down into the lower tray.
