Electrical Problem!

OK, I have no clue what is going on here. and its making me a little upset. I spent last night installing the drive line in my SD. as some of you know I've totaly over hauled the power train and installed a manual transmission... well last night I had every T crossed and ever I dotted (mechanically.......) and then I tried to start it and no go.
I started the car last week without the drive shaft, and it started just fine. so I don't understand what could have changed between now and then.

First I checked the battery for voltage. None. so then I put a charger on it thinking it when dead since last week. the charger sparked then popped it breaker. So i disconnected the battery cables and put the charger on it. this time the charger did nothing. so then I got another battery. when I hooked it up, major sparks... OK i have a major short.
I disconnected the cables from the starter, there is no short in the cable from the battery to the starter.
I then started disconnecting and testing each wire. all the wires seem to be fine, except this one.


when I test the voltage from the positive side of the battery to this wire I get 12.5 same as if i tested from positive to ground.



When I test Ohms to ground I get 2.4



Is this normal? where does this wire go? its the large red wire leaving the distribution block.

Have you tried putting all this back together and unhooking the alternator? I know that is the only piece of the electrical system that you have introduced since last starting the beast. Perhaps something is not quite right there? Other than that I'd have to flip through the wiring diagrams.

A key-off "major short" can be only the alternator and its solenoid or the starter. If those seem OK them maybe you pinched a wire somewhere.
