Tony -

thanks so much - great advice - I know I have power to the relays because it clicks when I push the horn button....so I assumed I had power to the horns but needed to verify.....

and so here's how it turned out (ie, here is the difference between people who don't know ANYthing and those who have done all this stuff before!):

1. Tried to see if there was power to the horns, but the multi-meter I was using was apparently kaput. so went to get a new mulit meter (which ended up being a while-you-are-in-town shopping excursion!).

2. Got the multi meter, and went to bench test the units - the shorter unit made NO sound, the longer horn made a little "ip" noise - that is all.

3. tested continuity - nada on either - For those who don't know, I used the multi-meter ohm settings to see if there was any needle movement when touching the contacts on the horn. Polarity does not matter - either side for red/black on the multi-meter leads, we are just looking for the needle to move.

4. recalled a comment about the adjustment screw from a link on repairing the 964 3.2 horns - and went about turning the screw on the back of the horns. Bear in mind, mine is a '76 tub, I had NO idea if the horns were the same as the 964 horns or not - turns out, NOT, the screw that the link said to turn 'counter clockwise' made no difference until I turned it 'clockwise' to the point that I had some continuity - whereupon the horn made a 'mew' noise when bench tested.

5. feeling somewhat bolstered in my confidence, I set upon tuning the horn to its loudest noise level while powering the thing and turning the screw. ahhhh - a really aggressive neutered sheep noise has been attained! "MEEEeeeeeWwwwww!"

6. Onto the shorter horn now - with my new-found knowledge of the 'adjustment screw' - and bingo - we have NOISE!

7. Replaced the horn assembly structure back onto the chassis, saving the attachment of the longer horn to the frame for later so I could get to the screw that holds the whole thing to the frame.

8. One final snug up on the screw that holds the longer horn to the frame - and - SNAP, I torqued the screw off. sigh. wire-ties for now, but I have noise that should astound people that i"m honking at since no one has probably EVER heard such a sound - a combination of an angry neutered sheep and a piccolo! Victory is mine.

The LEARNING POINTS:

1. ask for advice, and read the stuff that is out there. Had I not read about the 3.2 adjustment screws, I'd have taken the damn horns apart or purchased new ones.

2. make sure your kit is in order. duh. who knew multi-meters went bad? sigh.

3. do the easy stuff first - had I fiddled around with the adjustment screw I would not have needed to take the horn assembly off the chassis....

4. THANK THOSE WHO CONTRIBUTED TO THE SOLUTION!!

And so: Thank you everyone - another great session and another victory! I now know a little bit more about these great machines! And thanks for the wiring / current flow diagrams - that adds to the knowledge base for the '76 model year 911 cars!

all the best -
