Thanks for all the replies to my previous query about a broken
TR4 horn. I believe I have isolated the problem:
1) the steering column has continuity all the way from horn
button to pinion gear
2) the steering rack housing is grounded
3) the horn works like a charm *if* I jumper between the rack
housing and the top of the pinion gear (just below the lowest
rubber bushing)
What's the deal?? I guess there is supposed to be electrical
continuity between the rack and the pinion gears to make that
final connection to ground, but it's not happening!!
Is there supposed to be _conductive_ grease in the steering
gears? Could someone have filled the rack housing with
_non-conductive_ lubricant? What is the RC constant of 90-weight
anyway? Am I losing my mind?
I've fallen...
