I have a drain of 4+ amp's and got it down to my trailer circuit. I've traced it in to the cab I bought a new controller thinking that it was my problem because when I unplugged it draw was gone,But the draw is still there even now with the new controller. Any help would be appreciated thank's

 

I've been helping too. It's got the draw on the 40A trailer fuse in the PDC. As mentioned the trailer brake controller has be replaced. Then we separated the trail light loom and no change so the draw is in the cab.

 

Addon.

 

We unplugged the PCM and central timer and 50A battery fuse. Draw is gone. Plug in any of the above the draw is back. So I'm assuming PCM and central timer have issues.

 

Another addon... just talked to the customer and just going to put a cutoff switch.
