earthing steering wheel column for horn


Recommended Posts

Is it the same as on the IRS cars with an earth from the steering rack to chassis? Don't rely on the splines at the U/J's for continuity either, use a link wire between pinch bolts.

Hi Neil,

firstly under the horn push button on tje steering wheel there is a spring loaded contact

Item  53    https://www.moss-europe.co.uk/shop-by-model/triumph/tr2-4a/steering-suspension/steering/steering-tr4-4a-1961-67.html

Also at each of the two rubber UJ there should be an earth link wire connect each side of the rubber to the steel steering rods.  These must be fitted

Item 71, the wire lead, needs to snake though the rubber doughnut hole from one side to the other, to make the ground circuit.

Also Item 94, the lead from the rack to the chassis, which is necessary if your steering rack is rubber mounted (some use the solid mounts).

The horn ring, Item 4, is "live", supplied by the black and purple wire from the loom under the steering column. Pushing the horn button makes the contact to ground via the stiff copper wire/spring that holds the button against the steering wheel hub, and thence through the steel inner column.
