Hey guys, our 2000 7.3 keeps draining the batteries after a few days. Come to find out there is 5 volts constantly on the “S” wire on the stater relay. So came back to fuse #20 under the dash and it has 5 volts on it there a well on the left side of the fuse. When I turn the key over, I do get 10 volts on the right side of the fuse. I unplugged the clutch sensor and still 5 volts. I even unplugged the wires going to the ignition switch. Any ideas where I should check next?
