Is it the Lares 209 coupler? If so it’s non conductive, I tested that before fitting mine. Daft question, did remove the blue link wire? Didn’t really see the point of that. If you did remove that, then perhaps you have the outer and inner column shorting somewhere? Hope you get it sorted Sent from my iPhone using Tapatalk
In later Bays, you need the link wire to earth across from the inner column to the steering box/chassis.
Yep. Our earlier buses need the coupler to insulate - the wire down the column passes through it to attach on the box side. The outer column is the other path oop the column. Not that mine works, I gave up and fitted a switch on the dash.
The Early setup was a bit barmy. Kick the steering column or thump the wheel, and the horn goes off when you go round corners. Classic design
But if you try to hotwire it with the steering lock on , the horn goes off as it is grounded by the locking pin ... which may have been a serendipitous but dubious "safety/security feature"
