Hi, I took apart my steering wheel to repair the metal wings. I have a 220 with the semi rectangular volvo logo at the center, and the too thin somewhat triagular/rectangular metal (too soft)activators. I am using this vague description so as to i.d. the mech in the interiore. There are 4 screws with springs that hold the above mentioned assembly in place.

I can't remember how the ground wire attaches to this assembly???

I checked GCP for their schematics but there was not enought detail. Is it just an eyelet arount the screws attached to the spade connector? I really can"t remember how this was put together. Any suggestions welcome.
Thanks patrick.

The "bow-tie" steering wheel should have a male spade on the metal portion of the emblem assembly. The wire coming up thru the steering column needs a (shielded) female spade terminal.

Patrick;

If it's the standard Amazon Wheel, wire does not directly connect to the switch assembly...it connects by way of the spring loaded plunger assembly (36,37,38,34). If force required to activate horn is too low, foam (23), which hold sides of switch (22,25) apart, needs replacement.

the 68 220 mech really does not work this way. For starters the center of the steering wheel is a plastic rectangle and there is no push button contact thingy. I have had the s.w. you have pictured above but my present one is different. Specifically the black wire ends in a female spade connect which has to connect to "something". That something is the mystery. I took it all apart last fall and it all seemed clear to me then, I put all the bits in a bag, but I susupect I had one broken bit that I chose not to put in the bag. Since then I seem to have lost some brain cells, (banged my head at least twice on low ceillings in basement that's my guess!). Basically this might be really simple but I am not getting it. My mech has 4 machine screws aprox., 2cm long that have threads for only the 1st 0.5cm, the smooth part of the screw passes through the length of a cylindrical spring. The screw bottoms out in the steering wheel, the center section is held away from the s.w. by the pressure of the springs. I will need a K words to do this justice, I will find a pic somewhere. Thanks for the input.

You've described the "Bow-Tie" type steering wheel found on early 140 models (up to 1972). I had one on my original Volvo 145 (1994-1997), but my Amazon is a 1967 so I can't go check for you directly.

Look up the schematics for the early (1968-1972) 140 series and you should at least find the right picture. Similarly the 140 wiring diagram from that time period should also help (what grounds where).

Good luck!

I have a different model than you, but when I went to do my horn I was at first very confused. IIRC, the wire running through the steering column is ground for the horns and the horns are already connected to + somewhere else. You complete the circuit by pressing the plate on the steering wheel which grounds the wire coming through the column.
