12 volt wiper hook up

[supernotch]

i'm putting back together my 63 notch and am having trouble with the wipers. it's a 12 volt wiper and i want to get it working off my push button but not sure where to hook up the brown wire.

is this going to be possible, is there a way to bypass something to make it work

brown usually equals ground wire

it was hooked up to a 12v switch but i want to utilise the pushbutton. we first hooked it up just using the 3 wires then the brown as an earth but it would just turn on without using the switch and you couldn't turn it off.

If I remember correctly, one of the wires is the 'park' for the wipers so that no matter where they are in their sweep cycle, they return and 'park' when you turn them off. And using both speeds with the push button switch isnt possible. You will need to decide on having one speed with the push button switch or two speeds with a separate two speed switch.

The push button switch can handle the 12 volts as many others on here have stated. They were a pain in the ass back in the 60s and were frowned on by VW service staff due to mainly the headlight area burning contacts and were costly to replace. The addition of relays to headlight high and low beam fixes that problem. Put one on parkers as well if you like.

As for the wipers, this is the connection on my 64 with pushbutton. This was a NOS unit fitted to the Notch when restored around 2001:

53 purple trace on switch to black on 12 v wiper motor

53b yellow trace on switch to yellow trace on 12 v wiper motor

53a black switch/fuse box to purple trace on 12 v wiper motor.

Not sure if the single speed wire from the motor is the high or low speed but maybe I did connect to the high speed one. Also, I seem to remember another wire from the wiper, maybe a second brown that has to be capped rather than connected. Connect the above only and see if it all works including the variable speed with the top disc on the switch.

As for driving in rain they are satisfactory at best compared to modern cars and after all, my car is only driven a bit as there are only two known roadworthy ones of this model left in Australia.

I was working with a 1967 wiper motor that I plan to use in my 1964 push button Notch when I convert to 12V. I could not get anything to work and had to go back home and search the forum.

Just as DHanna writes in an earlier post the factory seems to have flipped the colors for terminal 53 and 53a somewhere between 1964 and 1967.

The thing is, the 67 wiper motor is a 1 year only part. It's a variable single speed motor, while 68-70 are 2 speed motors. Those will work just fine with the PB switch. For the 2 speed motor you need the 2 speed switch, and then use the PB switch to power it.
Just something to keep in mind.

I swapped the two wires and the wipers work perfectly.

Thanks for the clarification, HenrikL.

And thanks to DHanna for the very useful information!
