Wash Wipers

[Alan Whitaker]

Hi All
Is there a relay on the S for the wipers or are they fed via the stalk. It looks on my drawing that full power might be through the switch. Any help on this, as with my side and head light switch I have to use relays. The Corsa uses a relay so I might have to put one of these in if the wiper motor works the same way.

Might have to work out how this works

As standard there is no relay Alan, load goes through switch.

[Alan Whitaker]

That's what I was thinking, well back to Penny then

[Penelope Stopit]

Have you sorted this?
If you haven't got it sorted, I need the switching posting, how many positions and are they marked, how many wires and what connects to what when in every position including the off position
There could be many combinations of continuity depending upon the switch position, off position may have a contact
When in 1st speed position maybe only 2 contacts are made, now switching to 2nd speed maybe 1st speed is still made plus another, intermittent position etc

[Alan Whitaker]

Not yet but I did check out another 3 indicator switches and the are all the same.

Just replaced the battery in the meter and I have the following
on Terminals 31 and WH I have continuity in all positions
53 and 53e continuity in position 2 and 3
53a and J position1 intermittent
53a and 53 position2 slow speed
53a and 53b position3 fast speed
53a and WO continuity in wash wipe

Thing is I have the S wiper motor

[Penelope Stopit]

Good info above, the only problem is that I can't check it out myself, I will have to bank on you being correct

I think your S wiper motor is made by Lucas and has the 5 x Terminal Park switch built into it, I need to be sure of this, I will wait for reply
Is your motor 2 x speed?

Do you want me to have a go at this?

It is a 2 speed motor with park

Alan

[Penelope Stopit]

OK. Do you want me to have a go at this while you get on with something else? Do you fancy doing it yourself?
There's no point in both of us spending time on it and I don't want to put time into this if you're working on it

[Alan Whitaker]

Yes that's very good of you to do this, Many thanks

Alan

[Penelope Stopit]

OK. Do you need intermittent wipe? If you do need it (don't bank on it being possible just yet), what intermittent wipe relay will you be using?
Do you reckon that thumb wheel for intermittent wipe time/delay is a potentiometer/variable resistor....I do. If you can work out what terminals on the switch base connect to that potentiometer it will help, turning the thumbwheel should give a variable resistance across 2 terminals
I wish I could find a Corsa B circuit diagram as it would save you having to check the switch out and also make life easier for me

S1 wiper connecting block - 2 speed self park no intermittent

Perhaps that isn't a potentiometer thumbwheel
Does the thumbwheel click into different positions?
I think that thumbwheel switches in different resistors between terminals 53a and J
Check the above and post results here
How urgent is this? I can't work on this in the morning as I have other things to get out of the way
I will check back here in the morning before going out

Thank's, I appreciate you are trying to help, I have no problems with the wiper motor wiring, it's a Corsa B wiring diagram that would be nice but I am getting my head around the problems without one
A Corsa B Diagram may help with the intermittent wipe wiring but I am not banking on this as this baby is a one off

You asked about Fog/Spots wiring for staying on with dip or main beam, take the supply for the relay switches off the side/headlight switch, the one that goes from side/head switch to supply the column switch

[Alan Whitaker]

Hi There is a pr of leads that goes to the pot the pot reads
20K scale short delay =5.20 on the long delay it reads 0.69

This is the crcuit I've used.
It will give an intermitent wipe, and 2-3 passes when you use the wash function.

This is the relay,



I havn't tried this with a variable delay, i assume that this would drop into the "I" line.

like so

Cheers P

had been thinking that there would be VERY few occasions to use the dips within the spots - fog/falling snow so maybe not worth the extra wiring/switches / relays. Had thought taking the spot activation from the car main beam through a switch (designated spot main) to a changeover relay - n/o to the spots (so would work as legal on road)each spotlight is separately relayed as 100w and then when the changeover relay is unactivated and the n/c is +12v this is then used via a switch (designated spotdip) to activate the spotlight dipbeams again individually relayed and 80w. Could you please (at your leisure as probably won't do this now but maybe sometime in the future) run your mind over that and confirm if would work.

I like that and thanks I've always wanted the intermittent to work.. is the above for the standard S switch.? Oh and wipers on with wash pure luxury.

Thanks

Standard S switch,
but in some the 53-2 connection has no wire in the plug, though its there in the switch.
thats the orange wire, I had to add it.

personally I hate auto wipe when wanting wash - especially in the winter when it gives wipe when the washers are frozen so then also gives a windscreen you can't see through. I prefer separate
functions. My BMW gives 4 wipes just to make sure you can't see.

[Penelope Stopit]

Thanks for the information, I've a few ideas/thoughts on this, must go out now, will post back this afternoon

Alan
How urgent is this job?
