Steering wheel ground for horn pad Posted by Pete [Email] (#2000) [Profile/Gallery] (more from Pete) on Tue, 2 Jul 2002 16:33:35 Members do not see ads below this line. - Help Keep This Site Online - Signup |
Does anyone know where the steering wheel / column are grounded? Recently my horn stopped working on my '88 900T, so I removed the steering wheel cover and the lower stalk cover underneath. I determined that power is coming through the slip ring to the horn switch pad (able to honk when shorting power wire to known ground under dash). There is also continuity through the horn switches. However, I discovered there is no ground at the steering wheel or column for the horn pad ground wire that plugs into the steering wheel (can't activate horns when jumping power wire to ground wire, and no continuity between steering wheel/column and known ground). Since the wheel/column assembly are mounted through bearings & u-joints (bad grounds if any) I'm thinking there must be some other means of grounding the wheel/column. I pulled a steering wheel off at the wrecking yard and did not see any brush or slip ring that would ground the column/wheel assembly, only the slip ring assembly for the power lead.
Does anyone know how the wheel/column assembly is grounded? Is it somehow done through the metal bracket for the stalk switches? I don't know what else to look for, and the Bently manual only shows ground at the wheel, no details.
Thanks.
