ok did a 6.0 swap in a 98 z..car started and ran fine on jack stands, dropped it to the ground..i started the car and went to pull out and stalled the motor...now im not showing any voltage on the gauge, car will not turn over what so ever, no power for windows or anything...all the fuses in the panel where the ignition fuse is are not getting power whatsoever.....sounds like a relay behind the glove box is clicking like crazy....any ideas??

 

Are the battery connections clean and tight? Have you tried a different battery? Someone else will be sure to know this because this is a shot in the dark for me, but I think there's a fusible link between the battery and the fuse panel that could have blown. Based on the clicking sound I doubt that's it, my bets on a bad battery/battery connection/bad ground.

 

its a new battery,,,and i checked the connections on the battery....one thing i need to know is where all the grounds are....that will be the first thing i check when i get time
