I just put my engine back in my car and i have a dead short somewhere. If i put a volt meter on the + battery cable (not connected to battery) and the + terminal on the battery i get 12.5v (the negative terminal is connected). I also have continuity between the + battery cable (unconnected) and the - battery terminal(connected). The alternator and starter are okay and are not shorted out. All ground cables are disconnected from the engine block. Where could this short be coming from? If i have to test each wire how can i do this?

thanks

The short you are speaking of could be something as simple as the light on the hood or the juice required for keep alive memory of the computer. To find the short pull the fuses one at a time and check again. When the short goes away you have isolated the circuit. I would also measure the actual current draw of the short. If it is small there is a good chance it is one of the above and therefore normal.
