Our new steering wheel (leather and mahogony) arrived last night VIA UPS!!
Upon removing the old wheel I found a loose pin lying there - I've no idea where it came from. Also, I thought it strange there was no spring - and the horn does work! Anybody have a good picture of a circa '81 steering wheel assembly - with the hub removed? I saw one about a month ago here - can't seem to find it in the archives.
OK, I installed the new wheel and it looks great - now the horn doesn't work. From the image Jim sent it looks like I may be missing part #4, the insulator.
Sheez - the horn worked before I removed the steering wheel. I made sure I accounted for all the pieces as I took it off - and put everything back the way I found it.
Can anybody explain how the horn works on my '81? Could the problem really be the missing insulator?
What are the pin measurements. Or take a picture of the pin next to a ruler or a dime.
Part #3 in the AIM drawing is called the Eyelet may be the pin you are mentioning. The Eyelet has a Spring #2 under it and it is spring loaded up through the Hub Asm and up through all of the steering wheel and telescope parts. It then contacts a stamped L shaped leg on the Contact Asm Upper #7. When you press your horn button (#9, #10, #11) it presses on the Contact Asm. The Contact Asm closes and goes metal to metal providing a ground that closes your horn relay and blows your horn.
If the eyelet was not spring loaded it might or might not reach the leg on the contact asm (depending upon build tolerances.) If it doesn't touch the leg - no horn.
The plastic collar or Insulator #4 holds things together and keeps the eyelet central. Without the insulator the eyelet might touch other metal parts in the steering wheel and hub area. Then your horn will blow continuously.
