Trailer harness problems

I was testing my trailer lights with my 96 f150 and at first everything worked except the pass side turn signal of trailer.Then I got my 12v test light and tried to see if I could get it to blink in one of the holes on the harness.Anyway maybe I shouldnt have done that because now I only have running lights,no brake light or turn signals.The alligator clip was on the ground of the harness and when I touched one the holes it sparked(test light didnt light up),after that only running lights.I was looking in my Haynes manual at the <a href="http://motorhaven.autoanything.com/"><a href="http://motorhaven.autoanything.com/">wiring diagram</a></a> and it shows fuses located under the hood.Did I just blow a fuse?The truck lights all work though,just only running light power to harness.BTW it got dark and I havent looked under hood yet.
