    I ran a load in this morning and the blinkers were working when I left home and went to turn off the highway and I got nothing tried the hazards they didn't work either. got it home and went through the fuses and wiring and don't see nothing, could it be the signal lever switch? I've never had a problem with it cutting out or anything before it quit, any other ideas I've never conquered anything like this

    Check fuse/breaker F2-D, should be 20 amp. This powers the flasher then it is straight to the signal stat.

    interesting I don't think I pulled that one I checked all the other breaker ones and not sure how to check relays, I better go check that fuse before I buy this new turn signal switch lever I ordered
