Battery Draw

[shotmark]

Hi all,

I have a 2014 Chevy silverado.

 

I just had a draw test done, with all the fuses pulled out of the engine bay, driver side, and passenger side.

 

its still getting a 45 mili amp draw with all that disconnected, im stumped.

 

I have an aftermarket radio installed ( it has the E-Z gm hook up wiring & has been installed for over a year)

and

an after market remote start which has been on the truck for two year, since i got it.

i haven't had a problem like this before, i dont know what could be drawing off the battery.

45 mA doesn't sound that bad, especially with vehicles these days and all the increasing electronics. Is there a problem with the truck discharging the battery? I've come to understand that anything under 50mA is acceptable these days for a KOEO battery draw. When my 2003 Silverado had a parasitic draw from the cluster, it was pulling about 150mA and would drain the battery in about 7-10 days if I didn't drive it. After I fixed it, it went down to about 40 mA and I never had any more problems. Since that truck was an LT, it had the memory seats, memory mirrors, auto climate, etc among other things. All those modules draw a bit of power to keep the memory and settings, and everything I read indicated that 40-50 mA for even that truck, was acceptable.
