Default 2004 2500HD amp draw

Havent driven the truck in a while. Today the one year old battery was dead. Got it charged and put it back in. I have a .2 amp draw. When I connect the amp meter in line with the negative cable, I get .75, and after 10 seconds or so goes to .2 and stays there.

I pulled every fuse one at a time inside and under the hood with no change. Any ideas?

Could a relay be stuck? If it weren't -6, I would go back out there and check.

EDIT-After thinking about that for a minute, the power to the relay should be fused, and I pulled them all one at a time.

Try cigarette and radio fuse. I had a similar issue. Is your vehicle equiped with OnStar? Make sure your not opening any doors at all, which can cause the computers to wake back up.

I will check those again this weekend. It was really cold and I was going pretty fast. I had the door open to pull fuses, but the latch was closed so the truck thought the door was closed.

When I initially put the meter in line with the negative battery cable, the draw is .75 amps. After 10 seconds or so, it drops to the .2 amps. I left it like that for 15 or 20 minutes, and still .2 amps, so I am assuming everything that is supposed to be sleeping is sleeping.

The hood was open, but I have no under hood light, and I didn't see any electrical connector on the latch.

I feel for you. I had a similar issue with a .35 amp draw. Went through all the fuses to no avail. But I must have missed one fuse on my first try because on the second try I found that pulling the fuse for the audio amplifier (Bose) dropped the parasitic draw to .002 amps. A new amp and all is well.

Its the ipc/dic fuse. I am going to send the cluster out for repair.

Before I found that fuse, I pulled the inline 20a fuse that came with the racetronix hotwire kit. No change in draw, but the fuse is burnt yet still working. I have a walbro 450 in the tank, -8 and -6 fuel lines. I am not even working the pump hard yet, the truck is otherwise stock. Truck will be turboed soon.

Anyways, can I safely add a bigger fuse? 30 amp? Should note that fuel pressure is 51 psi, as high as I can get it with the orifice thats in the aem adjustable fpr. I bought different orifices, but never got around to changing it to a smaller size. Not sure if that would have anything to do with it.

Any advice on the hotwire fuse? Signed up for the online support forum, but have not been approved yet.... I don't want to call a dealer because I bought the kit direct from racetronix.
