Hi all. On my 01 F350, I have a short somewhere. I have two new batteries, and two new alternators. When I pull the ground wires off and hook up a meter, the draw on the A circuit is about 0.484. If I pull the radio it drops to 0.33. But that isn't milliamps. That circuit in the meter has a bad fuse. Only the A circuit works. It drops if I pull #22 under the hood. Battery box junction feed? What is that and where is it? I have tried all the fuses and relays under the hood and in the cab. Are there inline fuses somewhere to check?
Thanks for any help.
