Intermittent Wiper Delay

[mopoole]

Have been contemplating upgrading the wipers to variable delay as I find the fixed timing is never right for the drizzle; has anyone done this using a modern relay(i.e. a six pin one). Is it possible and if so how did they wire it up? Presumably you replace the thermal delay switch; where does that hide? Can't see it anywhere in the ROM.
Any ideas appreciated

Many thanks
Maurice

I used this one supplied by Retronics, very easy to talk to them and v helpful. There’s a few out there but pleased with the product and company.

Being a retired electronics engineer, I made my own. Cost about a fiver.

You would need the uProcessor chip (cheap) + a few other discrete components and a small 12v relay, then of course programming capability (not so cheap) and construction skills..

As I thought, you were just showing off rather than helping anyone. Each to their own.

I do make stuff like that because I can !, I see it as a challenge and they function as I want them to.

Not so I can criticise others.

My car has numerous uP's, central locking / alarm has two, immobiliser has one, wiper delay has one, variable speed cooling fan has one, dual engine temp display has two, low fuel warning light has one, fuel bypass has one, radio timer has one.

Sounds like you're in a great position to be able to put together some instructions on making quite a few electronic circuits for the Stag. You can send the sketches - and even handwritten notes - to me and I'll punch them into a document for the technical section.

Have decided to go down the road as described in Car Builder Solutions catalogue and bought one of their relays. Full? instructions appear to be in the catalogue/website with an added bonus of being able to actuate the washer as well. Don't know how feasible it will be but will give me something to do while it's cold; at least the garage is warm. Need to consult wiring diagrams.

Integrating it into the existing wiring is the tricky part, as with many electronic additions, but I'm sure you'll get there.
Like you say, something to do while weather is too cold to be outside etc.. is beneficial.

Drew,
I accept the fact I have a rare expertise on that sort of thing. Electronics is something I have been involved with for over 50 years.
Only problem I see, is getting set up to program the chips can be quite costly. I already possesed that stuff anyway, so no cost to me.
Then of course there is the required program.
The actual hardware side is fairly straight forward, but circuit construction skills are needed.

Arduino offers good potential for such projects - using cheap hardware and open source software with a huge active community keen to share.

Here is an example of an Arduino intermittent wiper controller fitted to an MG, with information to build your own, including the code.

It is very easy to attach just about any sensor you can think of, or drive actuators, lights, displays etc. The possibilities are endless.

Brilliant! A great read - might try it out myself one winter. You never know, I might discover I have a rare skill!

Rather than flex about what I do know and be unwilling to share the info.

My old 1973 Rover p6 had a wiper delay system, it was very useful indeed, a very quick google has found that it is super simple and this webpage https://dev6.wirewheelswebbers.co.uk...-delay-system/ appears not only to show how it works, can go wrong but also how to improve the system.

A quick search on ebay found this https://www.ebay.co.uk/itm/Rover-P6-...-/333594868313

My 1993 RR classic also has a intermittent delay on the wiper function which is controlled via a single relay I believe. I will debug the wiring page and see if that could be adapted to work on the stag intermittent. Of course I will share this info and if any good it could be used by others.

50 years of tearing things apart only because I am curious about how they work

Go to vehicle wiring products they sell wiper delay relays,with fitted instructions,they also sell timer relays for the heated rear screen
