05 Avalanche key off amp draw

Where can I find the maximum "key off" battery amperage draw for my 05 Avalanche. I have 2.5 amp draw, all fuses are out, any suggestions?

My late model vehicles, Jeeps, Ford trucks, have all
drawn in the 8-10 MA range with the key off. The
industry requires that a battery must hold enough
charge to start the vehicle after 30 days of sitting.

I'd pull the relays too, checking the draw on each one.

A shorted diode in the alternator can cause this draw and the alternator will still work.
