Dead Short somewhere

[preachertom]

I have a dead short somewhere in my 1984 Peterbilt. I replaced the starter, because the parts store said it had a short in it, but it did not fix it. When you hook up the battery cables, the voltage meter goes up, and drains the batteries. I have searched and searched for this, trying every single light, etc, and havent' found it yet. Can anyone give me any ideas??? Please help! thanks. preachertom
