also i have tested for a draw and there isnt one.

 

Whats the key off amp draw?

 

im not sure...i am going to have it tested tomarrow and i will let you know....do you happen to know what it should be?

 

Really depends on accessories creating a draw, any good tech will be able to determine a reasonable draw for the truck. For instance if you have accessories that have a constant key off hot, you will have a larger amp draw. A factory truck without those accessories would be lower. Generally less than 35Ma.
