Leadership Team SLR No.77 Posted July 17, 2012 Leadership Team Share Posted July 17, 2012 Okay okay no comments about "what's a windscreen, what do you need one of them for?" etc etc, I have one and I like it 😬 But ..... it's always frustrated me that there isn't the the ability to make a "single wipe" at the push of a button. Both the Sevens I've owned ('95 & '99) have had the same wiper wiring, ie. 3 position rocker switch for off/slow/fast and a quick turn on/off will trigger the intermittent wipe, turn off by doing the same. I did investigate fitting a variable timer for the intermittent control but it was complicated as an add-on rather than a full control so kicked that idea into touch. Still leaves the same problem, if I want an "occasional wipe" it's necessary to do a double activation of the switch, effectively momentarily turning the intermittent circuit on then immediately off again. So .... does anyone have the knowledge of how a simple push switch could be added to activate the wipers for a single wipe, allowing them to automatically return to the parked position? Ultimately I'd like to add the push switch to the steering wheel but just getting the circuit active would be a good start! Stu. Link to comment Share on other sites More sharing options...
Leadership Team Garry7 Posted July 17, 2012 Leadership Team Share Posted July 17, 2012 Stu, I had the CC Dartford courtesy R300 (11 reg) yesterday (in the pi$$ing rain). That has the aluminium push switches fitted and it has a 4 push wiper switch, first push being intermittent, second slow wipe, third fast(ish) and fourth off. My 12 reg Roadsport has the same as you. Would they use a separate loom do you think? otherwise the wires may already be there? Can you tell I am an electrical genius? Link to comment Share on other sites More sharing options...
Leadership Team SLR No.77 Posted July 17, 2012 Author Leadership Team Share Posted July 17, 2012 That suggests that the current car is no different in that it's necessary to scroll through all 4 positions to get a single wipe Also as far as I'm aware the new push switches are all low current affairs and work through a control module therefore the wiring is likely to be completely different? I'm hoping that someone is going to be able to suggest it's simply a case of linking the wiper feed momentarily to one of the other wiper wires which will cause a single sweep ...... Stu.

Area Representative IanW Posted July 17, 2012 Area Representative Share Posted July 17, 2012 Stu, Are you handy with a multi-meter?  You need to find the two wires, that when connected together, start the wiper motor on the slow wipe. Probably easiest to identify by testing the contacts on the switch itself. Then you will need to fit a momentary switch to these wires. This should give a single push-to-wipe function. Pushing the button will start the motor and it will continue to run until the blades return to the 'home' position. Simples . Edited to add that if Caterham use the standard colour codes, Orange should be the live and Orange/Blue the slow wipe. Edited by - IanW on 17 Jul 2012 14:42:13 Link to comment Share on other sites More sharing options...
Stuart McGill Posted July 17, 2012 Share Posted July 17, 2012 Stu Wouldn't it be easier to fix the leaking garage roof or move your car to the other side of the garage? Unless your car actually goes outside now ? Link to comment Share on other sites More sharing options...
Leadership Team SLR No.77 Posted July 17, 2012 Author Leadership Team Share Posted July 17, 2012 Stuart you need to keep up mate ...... being RR'd today Light rain this morning though and again became frustrated with the lack of an easy single sweep for the wipers! Ian, I'm not sure it's so simple? There's some kind of control module built in to the wiper mechanism that controls it. If I create a simple momentary link to the slow speed wipe surely all this will do is activate the intermittent mode in the same way as if the switch is activated for a short time? It would be a half way solution in that a simple push switch on the steering wheel could activate the intermittent mode, a quick double push would give a single wipe, better but not the solution I'm looking for! Stu.

The momentary switch is replacing the on / off action of the main switch. Link to comment Share on other sites More sharing options...
Leadership Team SLR No.77 Posted July 17, 2012 Author Leadership Team Share Posted July 17, 2012 It will give a single wipe .... then around 8 seconds later I'll get another and so on! The wiring of my era of 7 is such that momentarily turning the wipers on activates the intermittent mode and it stays like that until the switch is momentarily activated again. It's currently not possible to achieve a single wipe with a single press. Stu. Link to comment Share on other sites More sharing options...
Area Representative IanW Posted July 17, 2012 Area Representative Share Posted July 17, 2012 OK. I think I understand. My 2009 car must not have this feature. Link to comment Share on other sites More sharing options...
elie boone Posted July 17, 2012 Share Posted July 17, 2012 It should be fairly simple, get a switchet and fused live wire, on 1 side of the push button and connect into the Orange/blue wire. Link to comment Share on other sites More sharing options...
Leadership Team SLR No.77 Posted July 17, 2012 Author Leadership Team Share Posted July 17, 2012 I'll give it a go. I assume that would simply introduce a live trigger to cause a single sweep without activating the intermittent mode. Thanks for all the ideas  Stu.

colindavies56 Posted July 17, 2012 Share Posted July 17, 2012 i was at stoneleigh and giles[one of nick chans cheshire set]bought a module which allows intermittent wipe,he also mentioned to nick about his little find, put a call out for him,he might be of help.

Leadership Team SLR No.77 Posted July 17, 2012 Author Leadership Team Share Posted July 17, 2012 I'm pretty sure Giles bought Andy Best's old car which already has the intermittent facility, but might do something extra Link to comment Share on other sites More sharing options...
TomB Posted July 17, 2012 Share Posted July 17, 2012 Why dont you stop messing with wiring and drive the thing  Its only been off the road for 600 and something days, no rush.....the gritters will be out in few weeks Link to comment Share on other sites More sharing options...

mav Posted July 17, 2012 Share Posted July 17, 2012 Intermittent is easy to remove and has not been fitted for a long time. There must be a system out there that will give you a single sweep at the press of a button / flick of switch. Link to comment Share on other sites More sharing options...
Mr Locust Posted July 17, 2012 Share Posted July 17, 2012 The Excel has one of these OCD intermittent wiper modules where you have to pull the stalk to start then catch it again if you only want one wipe............ Link to comment Share on other sites More sharing options...
mav Posted July 17, 2012 Share Posted July 17, 2012 here is a box that gives wash/ wipe at the press of a button, so don't wire in the wash option... Edited by - mav on 17 Jul 2012 22:38:46 Link to comment Share on other sites More sharing options...
