Battery Drain

My 2001 Limited Powerstroke X seems to have an amp draw problem when the truck is off. It may even be intermittent, hard to tell. The truck is equipped with dual optima red-tops, so they can handle a bit of abuse without showing signs of a problem, which is why I'm not sure if it is intermittent or not. If the truck sits for a few days, it has a tough time starting. I pulled both batteries and the alternator and had them tested on a machine - no problems there.

Were there any common problems with these trucks drawing juice when off? It's a limited, so there are plenty of bells and whistles to do funky things. I figure chasing a mystery amp draw is a potential nightmare - I'm hoping there may be some common components that others may have had problems with.

I don't know of any common problems on your vehicle, but you can remove the ground on both batteries and with a test light connect one lead to the removed ground wire and the other test lead to negative side of one of the batteries. If the light lights, you have a current drain(load on battery). This can be done with one battery in circuit as long as other battery not in circuit. If the bulb is lite up, you need to start pulling fuses til it goes out. Nothing in truck can be on (radio,dome light,anittheft,etc)or test is no good. The fuse pulled when light goes out is the faulty circuit.

Do not attempt this with engine running.
