Alert me when someone posts in this thread:

Thanks, Eric! One of the first things I did after buying the Sonett was research all the resources I could find. I have the Service Manuals, joined VSCNA, and then bought Ashcraft's Saab Electrics book. I bought primarily for the wiring diagrams but it has much more and is definitely worth the $75. It mentions in the book that you should blow up the schematics and then get your coloring pencils out. I digitized them broke them up into small pieces and digitally colored the wires. After I did that and sat down with my friend to figure out various circuits, he tells he's colorblind! But doing this exercise certainly made me familar with all the wiring.

Perhaps we should have an annual New England Sonett gathering to discuss the crazy things we have found and how we have resolved them (or may be just meet at the annual Lars Anderson Swedish Car Day.

In any case, yeah, I realized the wiring on the horn was the simplist wiring in the car but when it didn't work and I saw the wiring going into the column my head started to spin. I suggested to my friend who is helping me basically waht you said and he thought that just couldn't be because it would fail eventually!!!

I think I understand what you are saying but I am still in disbelief and have to question you to make certain I understand. The wiring is on the outside of the column and wrapped around the column??? How does it get from the center of the column to the outside? I don't recall seeing any single black wire coming through the firewall. In fact, I do know that the harness that comes through the fire wall and runs down the engine compartment near and below the relays and circuit breakers is carrying the BLACK ground wire from the column because it come out of the harness near the headlight and goes directly to my horn (only have one).

I believe what you say but I am thinking that is not what I have. I have posted several illustrations and one photo in my member gallery. The photo is of a steering column that a guy in Brockton has for sale. That photo seems to confirm what you are saying because you can see the wire looped around the column at the bottom. However, it was in the column so where does it come out? The other illustrations I have in my Gallery show the column and a VW column and how it is done by them (which makes sense). The illustration of the Sonett's column shows the wire in the center of the column but never shows it coming out!! because they don't show the whole column. So check these out (if you can, I don't think I understand how the Gallery works. The photos are in a folder appropriately named.

The thing I think is really humorous about this is that I have always bought Saab because of their creative and practical safe designs as well as their quirkiness but this car screams Middle School Invention Convention (not even at the level of a High School Science Fair).

Thanks again!!
