2003 Ford f150 king ranch trailer lighting problem
I am new to this and have searched but could not find a solution to my problem so I'm posting a new.
My 2013 Ford F150 King Ranch has a lighting problem on the boat trailer. On the trailer all the standard lights work. The right blinker also works. But the brake lights and left turn signal do not work. I checked the trailer switch and no power to that. So I checked the fuse box under the hood. The manuals says that #20 is what controls the trailer left turn signal and it's 10amp. So I replaced that fuse and it still has no power to that fuse.
Now fyi, I checked everything using one of those aligator lighting tools that attaches to a ground and has a pointer that lights up. So first I got a good ground and then checked the other fuses to verify the ground and the light came on on all of them. But on the new 10amp fuse I put in the #20 spot I got no light.
Is there something I can check using the aligator tester that would tell me what needs replacing. Not familiar with relays or what they are.
Thanks in advance. Mitch
