Hi all.I am restoring a beated up F4.This is the problem I am having at this moment.A brand new Honda original left switch( no cheap) was installed.With no signals F-R connected and the horn missing.With ignition on when I move the signal button to left or right I short the 10 amp fuse.Wiring looks ok.Any ideas on what the problem may be?.Thank you

 

The turn signal wire is shorted to ground - trace it through the loom.
