Default 12v on the engine block when starting? Help!

Okay heres the deal. When everything is acc everything is fine, but when you try to start the car the starter clicks and the engine block has 12v. If we keep trying to start it and something metal is touching any ground it gets red hot. But sometimes the car starts. We have tryed swaping starters and the starter relay. The battery is reloacted to the trunk and the under hood fuse box is inside the car now. The only thing we can think of is the remote wire for the starter is grounding out somewhere but where does that wire run?

Starter is shorted internally. Bench test under the same conditions to verify.

OK. What about the ground side? Do you have a GOOD SOLID ground from the motor to the battery? Have you tried disconnecting the solenoid wire at the starter and then cranking the key to see if the solenoid wire is the problem? I think if the solenoid wire was shorted, It would melt the ignition switch and kill the starter relay.
