hey i dont know whats going on but all of a sudden my horn fuse that controls my brake lights keeps popping i disconect the battery and it still pops as soon as i putt it in and hook up the battery>??? weird just started a day ago??

 

bump. im having the same problem in a 91 crx. stop/horn fuse keeps blowing instantly.

 

this circuit has only the horn and brake lights....

there is a white/green wire that feeds both.... check the horn switch area, brake light switch area, horn relay....find the short... it's probably a pinched wire-to-ground

the wiring diagram found in the shop manual is most helpful for isolating problems like this
