Trailer Brakes

[Cdunnje]

Hi all, the age old question, why aren't my trailer brakes showing connected and functioning. I have a 2015 Ram 3500 with factory controller, bought unit used. I have a socket tester, bumper mounted and bed mounted plug receptacles have tried both plugs, tester shows no signal with gain on 10 and slider fully over. I am getting a light pulsing on tester and when I put Vdc tester to brake I get zero voltage but the same ligh pulsing. Any thoughts? I've checked fuses or at least as many as I could identify seems to be 5-6 of them. Thanks, really appreciate, worried dealer would look at me as if I had two heads. Jeff

Sorry that I can't help with a Ram, but Fords have 2 sets of fuses--the ones for the trailer are all under the hood. Does the Ram have a second fuse box?
Are you saying you have connected to the trailer and it doesn't recognize the trailer? Or are you saying you can't get a tester to show power?
Do you have a friend with a trailer to hook to and see what happens?
And most of these connection problems end up being a bad ground...

Also, welcome to the forum.

Thanks Joe for quick response, I was hooked to trailer and it showed trailer not connected, I bought plug in tester and checked receptacles and it shows no signal from controller, I hooked up voltmeter to receptacle and could not get any Vdc signal with slide on controller all the way over. Both with the plug in tester and voltmeter I am getting a pulsing light, very faint, but no light in tester , no volts showing on meter

Does sound like it is the controller--any hitch shop will have a tester that will show all functions by lightup, might take it by one of those and have them look at it. Just to confirm your thoughts.

Thanks Joe, I'm going to check fuses one last time in case I missed something then run it by shop
