Steering wheel turns light switch rod
When I drive my Model A'30 and turn a steering wheel, it also turns the light switch rod. Because the light switch rod turns it switches the lights on and off.
What could be a solution to this problem ? |

Re: Steering wheel turns light switch rod
There should be a small brass bushing at the top of the light rod. If that is missing it can cause your problem.
Bratton’s has them. This is from their website: “ This bushing slides up the horn rod to the top under the switch handle disc. This keeps the rod centered in the steering wheel. If this is missing, the horn rod drops to the bottom of the steering wheel hub, resulting in the lights turning on and off as you turn the steering wheel.” https://www.brattons.com/media/catal...6/5/0/5050.jpg

Re: Steering wheel turns light switch rod
Thank you Ray. So to install this bushing I will need to take apart light switch spider and bracket at the bottom of light rod, remove the light rod and put the bushing at the very top ?

Re: Steering wheel turns light switch rod
Yep. With a sedan or open car you can do that pretty easily. If it’s a pickup or a coupe, you have to maneuver the steering column into a position that allows extraction of the rod, which usually requires removing the whole steering column.

Re: Steering wheel turns light switch rod
These bushings are very cheap so buy a few and experiment. Could be you could cut one side and gently open it up. When you cut it cut the "return" at the top so the sleeve does not buckle .It might be you have the bush installed and the steering wheel hub is grabbing the light rod . I have had this problem and had to use a "dremel" abrasive wheel to slightly enlarge the steering wheel hole . I have done this several times over the years with different cars . I think this is most likely your problem .Just looked at one and it has a slit down one side anyway so maybe could open up gently I will try it .

Re: Steering wheel turns light switch rod
Had a similar problem a few years back - the steering box had been overfilled with grease that had gone most of the way up the inner column causing a certain amount of "stiction" betwixt column and light rod.

Re: Steering wheel turns light switch rod
Thanks for posting this. I've had this problem for a while, but it recently/randomly got much worse. I added the bushing from Brattons, cleaned/oiled & straightened the light switch rod and it works perfectly now, no friction at all between the steering wheel and light switch. Previously a normal turn would turn the switch all the way from one side to the other, flashing all the lights in the process.
For anyone who needs to do this, I removed the bail on the bottom of the steering column/switch, removed the switch, then removed the two bolts at the bottom of the steering column. Squeeze the spring at the bottom of the steering column, and a slotted collar will drop off the bottom of the rod, releasing the light switch rod. Pretty simple, took maybe 30 minutes in all. I straightened the rod by rolling it on a flat surface (tool box drawer) and looking for bends. Gentle bending was all it took to straighten it. I removed the two bolts from the bottom of the steering column which allowed just enough play to install the rod without bending. I ordered two of the bushings, they were both split, so you could probably install without pulling the rod. Glad I ordered two, they are so thin I squished the first one just opening the bag. Thanks for all the input above...it's nice to have a car where a significant issue takes less than 30 minutes to fix! |
