As seen on old pictures of race cars, some of them had the wiper mounted in an upright position.

How was this done technically? Shouldn’t it be sufficient, when in stationary position, to reconnect the connecting rod of the wiper assembly displaced by 180 degrees? Or do I commit a fallacy? 🤔

I think the easiest way to accomplish this would be to disconnect the "parking" wire. Sorry, I don't recall which one that is but trial and error should be easy enough.

With the wire disconnected you should be able to stop the wipers on any position.

Rich, I don't think that will work. The wipers on our Alfas, move in the same direction. Those on the GT move in opposite directions.

Blue-black is always hot so thats your parking wire, and to @donrencos yes, changing the way its attached the mechanism to the wiper motor is the way to go

As quadrifolio wrote, either method - rotating the lever 180 degrees on the shaft, or pulling the "park" wire - would achieve what you're after. Pulling the "park" wire has the advantage of being easier to implement, but of course, then your wipers would stop wherever they were when the switch was turned off; most likely, right across your field of vision. Some trial and error would be required to get them to stop at the vertical position.

If having the wipers in your racing field of vision is such a big problem, why not just remove the arms entirely? It's easier to remove the arms than to reverse the location of the drive lever.

Thank you for the inputs, I will try with reversing the location. 👍🏻
In this case it’s not about bad vision, but I’m owning the car on the picture and I’m trying to get it back to its former appearance from its active time.

Unless you will always be at the track, you’ll be forever getting questions about ‘what’s wrong with your wipers?’
Won’t do much for your vision either...but hey.
Q for the racers out there, was it about stopping the wipers moving and distracting at top speeds, or a .001% improvement in aerodynamics?

 

[Alleggerita]

More important than aerodynamics is visibility with low mounted racing seat ...

Changed splines on linkage ...

It’s pretty simple just flip crank linkage the 180 as you mentioned, don’t touch any wiring. Done it to my 911.

Now it’s more difficult to do a single middle wiper like on a ETCC gtv6 or and E30 that’s parked in the middle. You need to monkey with a greater swept area with the bell crank geometry or get a bespoke motor for a single wiper.

that’s a natural high pressure area. That’s why the intakes are located there or sometime even cowl induction facing the windshield.

depending on the cars shape, the wipers can lift clean off the window screen at speeds. Ways to alleviate this pre-windtunnel era was to put aero spoilers on the wiper arms, burrowed them in the cowl or add a “bug catcher” blind diverting or diffusing the air as on a friends sprint speciale
