anyone please tell me about replacing fuses in the facia fuse box - the 3rd from left has gone (says av ant ) or similiar where do i get these ? whats that one for? - cant find it in my manual.(1976 s3)

Try replacing with any of same rating. It might have failed of old age. If it blows then you are about to discover the joys of tracing faults in an italian car!. Actually the wiring diagram is one of the easier to follow assuming nobody has messed with the original circuits.

Iain, I have looked on my wiring diagram, 3rd from the left is marked fuse number 7, on the diagram there are three wires two red (one I think is thicker than the other) and one pink, the wiring seems to run to the horns via a solenoid/relay block which is under the wing near the alternator on a bracket on one connection in the fuse box. Do the horns work? They may be shorted out they do draw a fair current from memory, you could disconnect them both under the dash and reconnect one at a time.

There is a plug-in socket under the dash also connected to the same fuse, the feed side appears to a permanent live via the starter motor/battery, thick red lead. You might want to check the connector blocks that they are good condition, not damaged or melted. The pink wire goes to the clock, and onto the door marker lights.

I hope that helps, I have hopefully followed the routing of the cables and colours correctly.

The circuit diagram in the DT book on my disc does not show that the horns are fed through nr 7 fuse. It nees to be checked. Thee are more versions.

thanks - neither horn nor clock working!
will work on the horn
ive also found a male connector at the end of a thickish black wire - maybe it was in the socket that people mention - i cant find it
thanks
