No power to #25 wire (horn wire)

This is the wire that comes out of the wire harness on the drivers side. Any ideas ? Thanks !!

Isn't that a ground? completes the circuit by grounding, if that makes sense.

I'm pretty sure wire 25 only has power when the horn button on the steering wheel is pressed.

The 25 that comes out of the wiring harness goes to a fuse that is screwed into the dashboard, perhaps it is this fissile.

The horn wire is hot all the time and comes through a circuit breaker on the dash. The button in the wheel is the ground. It is the #25 circuit. Check power to and from that breaker, it could be a bad breaker or a bad wire.

Yep, going into the dash this week. Couple of gauges are real hard to read anyway.
I agree with rick. 25 wire is hot and the horn button is the ground when pushed on. Cheers

MY TM's only go back to early and A1's. How many breakers do a A2 have ? I found one wire #57 and another with no tag not plugged into anything..

A2 has 2 breakers, A1 has three, the third is the #77 circuit for the fuel pump circuit.

#57 is a ground and if it has no tag there is nothing I can tell you. the #57 is probably the dashboard ground if you are behind the dash where you see it. There should be a pigtail coming off of the dash that plugs into it unless the dash came from an A1.

hi

first look at the wiring diagram :idea: :?:
you wil see the 25 at the driver side between the steer and dash is gooing TO and FROM the fuse for the horn
at the driver side at the inner fender no 25 it is the connection to the horn button
at the passenger side at the engine side it is at the horn itself
at the driver side one no 25 is constand hot to the fuse
the other side go to the horn as 25
the button is the ground for the horn to make sound :D

the 57 wire is the ground for the flasher unit at C
also the ground for the dash
it get ground from the inner fender with a bolt near the alternator
wire 3 ground alternator and ground wire 91 left indicator also same bolt
