Wiper Parking

So I had the instrument cluster out (no fun) to replace the 3 rocker switches, upon reassembly the gas gauge stopped working. I knew the wires had gone back exactly so it must be the sender I thought which just a few weeks ago I had to repair. The float had let enough gas in that it didn't float. A hot soldering iron reflowed the plastic, fixed.
The float and the electrical part of the sender was OK, figured had to take the instruments out again (really didn't want to) just in case.....well hidden amongst all the rats nest of wires was a second red wire, unplugged. On a chance I swapped the red gas gauge wire with this other red wire and the gas gauge worked!
So where does this other red wire go, If you look down to the rocker switch one spade was empty, I tried it there and the wipers parked. But not in their proper location, I think 30 yrs ago I must have disconnected the parking.
So time to see the parking issue. it's easy to get to the wiper assembly and remove it. It was nasty, paint over spray, and the worm gear grease emulsified brown slurry.
Bosch motor is in very good condition, but the output shaft is worn and has play. I could reassemble with the worn shaft but....

Anybody have a good assembly ?????????

Try APE? I have a Berlina structure in my Super with the original single speed Bosch motor, if I remember the conversion right from 20 years ago.

Ape is sending a Milano motor/gearbox assembly which is supposed to swap in, in the meantime I reassembled the old unit and figured out the wiring...it works and parks but it's bangs a lot from the worn shaft.....we'll see.

One version of the wiring per the orange owners handbook, (everywhere I look they are slightly different), the thing is the wipers work and park fine with the foot switch #21 disconnected.......I'll have to try it with the B/W wire disconnected.
Just for ref next to it is a pic of the wiring for a Ti Super. Same dash rocker switches and foot switch but different wiring???? go figure.

While waiting for the Milano wiper motor from APE, I remembered Classialfaparts.nl in Holland and sure enough they list a new wiper for the TI and Supers. reasonable too, so there is an option if the Milano doesn't fit or whatever.

The car is a 64 TI, and I confirmed the wipers switch wiring is NOT per the orange GIULIA TI owners handbook but like the green GIULIA TI SUPER handbook!

I received the Milano motor from APE, disassembled and cleaned the sticky grease off and lightly lube it. It's a 2 speed and I decided to run it at normal speed rather than fast.
The mod required to adapt it to the wiring per the schematic for the TI SUPER shown was quite simple.
Note the dash switch has a Red and Green wires in the top 2 spades, and Blk/Wht and Green in the lower 2 spades. These are not changed. Verify the Green wire gets power when switch is off, red gets power when switch is on.

1) Cut off the Milano connector.

2) The Milano motor mod, unsolder and move the Green wire over to the Blu/Wht terminal.

2b) Open the plastic cover and clean the insides, while in there, working on the inside of the cover, carefully cut off the copper contact arm from the Black wire close to the cover.
Lightly grease the contact disc and snap the cover back on.

3) The Blu/Wht wire should then be extended with a length of RED wire ( from the old motor so it has a spade end).

4) The Blu/Red wire (difficult to see the thin red stripe) should be extended with a length of Green wire from the old motor ( so it has a spade end).

Note: The Blk/Wht wire is not used in my car , the foot switch is disconnected. Therefore the the lead from the car is left disconnected. In the future I'll try and have the wash/wipe function working but the car has a Dodge foot washer pump (bolts right in) that doesn't have wiper connections.

5) Connect to the car and test. Red to Red, Green to Green. When off it should park...Blk/Wht not connected.

Pics show Before and After Milano motor mod. Just green wire moved over, and cut off the copper contact arm from the Black wire under the white plastic cover.

Thanks for the very useful info on the modifications. Good to know on a used replacement motor. BTW, if you decide to swap the assembly from your old motor, try to get one from the same Bosch part number since the pulleys may not be the same size.
The subject covered in this thread seems to apply to various models and it would be useful to move it to the general electronic section.
Cheers, James

The linkage mechanism is the same only the motor and gearbox are now from a Milano, uses the same 3 bolt holes on the linkage.
FWIW here is the p/n from the original 1964 motor/gearbox.
