I have a 1976 280z and I bought the car with a '82-'83 zxt engine installed in it. All wiring was taken from the zxt. I wired everything up to the swap guide I found on here. I think I have everything correct. After all the wiring, hooked up the battery terminals and after a second or two the fusible links started sparking. I unplugged the battery terminals immediately. I thought it could be the alternator so I unplugged the wires to the alternator, but still same problem. I then took a volt meter to the engine block and valve cover with the positive terminal connected to the starter and I got 12 volts on the block and everywhere else that needs to be ground. Except for the chassis. It had 0 volts. I haven't had a chance to go through all of the wiring so I was wondering if anyone could help give an idea to what it could be. Thanks
