Firstly, thank you! Here's where I went wrong. I could have sworn I saw you ground the PB wire itself, not not the spade it was connected to in the first video. You can imagine my self inflicted confusion at that, because I'm pretty good with electronics and the schematic read that the PB ran to the horn button. I'm going that on the garage pints I may have consumed. But.. here's where it gets weird, and nearly successful... I went and tested again, with no hook ups changed, exactly as you did in this vid. Voila! Cherubs descended from the heavens playing my working horns!!! Then I moved the steering wheel. And nothing. Damn you Prince of Darkness!!!!!! So I pulled the cap, ensured the pin was lined up with the plunger. Nothing. Then I cranked the wheel a few times left and right, HALLELUJAH!!!! Seems like a ground somewhere isn't quite good. Where do you think I should start looking and how? I believe the path is horn assembly to column, ground joined at the steering rubber U Joint thing, down the column.. to ... where? Correct if I'm wrong but my assumption is somewhere along that path, which eventually comes back to the PB wire, I have a loose something. Thank you for the great vids!!!
Work your way back up starting with the BP under the dash to the purple from the steering column. Then go behind the brush, the brush itself then the horn button you will find your fault
@@planet6parts Will do, and thanks again. Great stuff! What I can't wrap my head around is this: I've had two relays in there while testing. The original, and a new one. Nothing should have prevented this logically from working. Yet... What did the trick for some reason was me doing the exact test you did. I had my test light on the PY wire that will power the horns once the relay is tripped, and then I jumped from batt ground the W2 (PB) terminal. And suddenly, hazzah, it worked for the first time ever since I've owned it. There was some minor sparkage (that's a word now) and in my joy I touched the W2 terminal a number of times and suddenly it didn't work BUT the horn button was now obviously triggering the relay, but no horns. In desperation I wire up the old relay, IT WORKS AGAIN! It was at that point I moved the steering wheel, it didn't work, but eventually I yanked the wheel around it worked again, etc etc. I know there's a wonky ground somewhere, but WHY DID IT SUDDENLY WORK as I followed that test. I can't figure out what might have changed. In my industry we call this "FM" which stands for "F***ing magic, but the geek in me wants to understand what handle I clearly jiggled by doing this. These old cars are mysterious buggers.
Wow this was timely for me. IT's a problem cruising along and the horn doesn't stop, while driving down the road. I'M going to detach until I can determine if It's a problem with wiring in the collumn. By the way, what does the relay above (the one you are working on) . I cannot identify in the haynes manual. Any idea? Thanks much!
The other relay is the ignition relay and you will see a 3rd which is a od relay but only on the a type drives. I hope the video helps you resolve your issue but sounds like it's constantly grounded if it does not shut off.

Well I'm glad I could help. Sometimes it's just a bad spade or oil so not getting a good ground. Sometimes it's a pinched wire also. Trial and error
