Batteries drained to dead, what is nominal drain on truck?

LittleBill,
My ammeter says 10A max.
I ran it there initially for the reading in my first post, just to be sure I didn't blow something.
Once I saw it wasn't drawing a huge amount I set it to mA on the 30 range of the dial. It began at around
70 and settled down to .1 mA after about 30 seconds. Held it there for about 1.5 minutes and it stayed there.
