Another wiper motor wiring query.

Post by monkey » Tue Sep 09, 2014 9:04 pm

Can someone confirm what type of wiper motor I have?
I'm guessing it's a 2 speed unit, but haven't got a clue! It's a 64 bus, but I was expecting a different unit than what's fitted.

My challenge is that it's fitted and attached to the linkages etc. and I can't read the terminal numbers to attach the wiring. Hopefully someone will be able to confirm what the terminals are from top to bottom..

Well, it's not a Bus wiper motor, so I can't compare the terminals to the motors I have. I'll look at the various Beetle motors and catalogues I have. I would think the terminal protruding out at the bottom of the picture is the earth (31).
Could you get a dentist's type mirror up there to read the terminals?

That's what I thought too!

So I gently loosened off the motor so I could check out the terminals. They are (from top to bottom):
54D
31B
54
31

I've dropped Peter good an email to see if he can advise me, as its one of his looms.

A bit of investigation shows that it's from a 60's bug.

Hopefully Peter will confirm that I wire to the switch in the standard way.

Well done!
The two 54 terminals are the speeds of the motor, and the 31 b is the switched earth.

Does that mean I need a 67 2 speed switch then?
Also, the loom piece provided by Peter has 4 wires, brown, black, black and yellow, black and purple. Wouldone of these earth bothe the switch and the motor, or do they need their own seperate earths.

What a pain it is when people swap over stuff from other years and models... :roll:

You don't 'need' a two speed switch as you could wire just one speed, the main thing is matching the terminal numbers from the switch to the motor, or finding the conversion chart online if the switch has different terminal numbers to the motor ( eg 53 and 53a are 54d and 54)

Otherwise you get strange earth/fuse blowing issues :roll:

I'll get confirmation from Peter G anyway, but it looks to me like I just follow the circuit as per the 66 and earlier diagram:

http://images.thesamba.com/vw/gallery/pix/398182.jpg

One question though. The switch earths through being bolted to the dash board, and (I believe) that the spare pin (31) shown as an earth in the diagram is for earthing other items that need an earth. So could I earth my wiper motor through the switch? That would utilise all 4 wires in the loom piece nicely

Looking at that link, it would appear that the motor you have is single speed. I was basing my comment that you had a 2 speed motor on the fact that August '65 up Bus motors are 2 speed with terminal 53 = fast speed and 53b = slower speed, so assumed that your 54 and 54d were the equivalent.
So, if it's single speed you don't have to concern yourself with a 2 speed switch.
Totally agree with your comment re swapping parts about between models and years. I think it is often due to people being impatient/expediency.The correct parts are out there, of that I'm convinced, it's a case of tracking them down!

Ok. Final question...
Can anyone confirm what the terminal numbers on the switch is?

Image

From the diagram i have seen it should be:

54D 31

31B 54

Image

Correct?

Are these the standard positions for connectors on a bus switch?

That's my single speed switch from my early 65 in your post. In this case there is no ground as the motor grounds itself to the frame with a copper strip under the mounting bolt and (i'm not sure) the switch may ground itself via it's mounting screw. I have the same 3 poles on both the motor and the switch.

This is the correct switch for a pre august 65 bus:

Let me know how it all works out.

I've run into another slightly confusing issue with the wiper switch. The instructions for the purple and black wire from the fuse box just says to connect to switch + . However the switch just has numbers for the terminals, So which terminal, does the live feed go to?

You are not reading the wiring diagram correctly..
The excel spreadsheet has names, coloured boxes withe numbers underneath....those are the terminal numbers. It shows black and black and purple? With 53 as black and 53a as black and purple at each end or something like that. The switch is marked with terminal numbers on the back by the terminals. The motor I have also has terminal numbers. You can find on the Web with a complete DIN terminal spreadsheet explaining terminal numbers.
Any help?
It is a Peter Good loom?
If you have ...His instructions are excellent. ..
