Short in wiring?

using a low range dc amp clamp, there should be <200 - 400 ma static draw depending on your electronics

it takes time for Modules to sleep after key off

a place to look for a high draw is the Alternator

I can help you determine amp draw circuit-by circuit if needed

I think this guy has been reading too many text books. Current draw is different for every truck, especially when you start factoring in gps's, qualcomms, hidden vehicle trackers, and a dozen other things you find in a typical truck these days. Only 200 - 400 ma sounds more like a car to me. However it is not a bad idea for finding battery draining gremlins...


Something like this comes to mind.

Not a bad idea for things that draw power, but 1/3 the wiring on a truck these days is also sensors and signal wiring. A clamp meter will not always be so useful on those.
