no turn signals at RV plug "HELP"
I need some help from a friend, I have lost both left and right turn signals at my RV plug. I still have running lights and trailer brakes. I also still have my turn signals on my truck. I can't find which fuse controls them, so any help would be appreciated

Look for a 20-amp fuse, #9, in the Battery Junction Block (under-hood power distribution box).
It's the fuse for supplying current to both of the trailer turn-direction relays, also in that block.
The coil for each of those relays is run straight from the truck's lighting circuit, so if the truck's blinkers are working, it's reasonable to assume the relays are also working (at least "clicking"). There's just no current being supplied to the contacts, so there is no current out to the seven-"pin" trailer plug.
Find Fuse #9. Look at Page 222 in your Owner's Manual for fuse locations.

I don't think either a 250 or 350 would make any difference in his wiring diagrams.

Old timers disease finally wins
Bud, You're correct that I don't have a clear picture of the workings of the brake system. I didn't realize that you needed the forward momentum to activate the trailer braking system. What happened is that I plugged a trailer into my truck plug that had the brake wire and the ground wire reversed. I assumed that either the EBC or a fuse had blown out. I corrected the problem but the trailer is gone for a couple of days. I will check the brakes when it returns and let you know. Thanks for your time. Wayne Adams
