Super-Soaker windscreen washer jets

(1/1)

Hi,
Since the weather has got a little milder I have been sorting one or two things in the early evenings - the sort of jobs that don't need too much light...

One task I set out to do was re-mounting the washer bottle which had been removed during extensive welding. When I realised that - although the RRC has a pump, it has no headlight washers, but the Disco has - I recalled an idea for improving the RRC's windscreen washers using the Disco's headlight jets to better cope with mud.

Here is how it went:

Cut here:



The plumbing was a mixture of original pipe (incorporating the dual non-return valve) and some spare petrol pipe that I had lying around. Unlike normal washer pipes this is located with jubilee clips due to the higher pressures expected:


The original headlamp washer relay was used since it incorporates a timer that limits each squirt to about one second - this is probably all that's needed and will help eek out the fluid supply. It was re-wired (so that it doesn't require the headlights to be on) by looping the blue (headlight-sensor wire) back into the main live feed. After testing I have decided that I will change this so that the blue wire is supplied via a dashboard-switched feed thus giving me the option of whether or not to have the SS jets coming on with the normal ones:


Here is a shot of them in action  :dance: :clap: :dance: :clap:


I have now realised that I have positioned mine wrongly: In order for the jets to hit the required place on the screen I have had to set them seriously cross-eyed - they should have been positioned in the bonnet dip about level with the existing jets and half-way between them and the rise. But anyway - here is a shot of them in the wrong place:


It's not an original idea of mine, but it's an easy and effective mod that took only a bit over an hour to do. I commend it to the house!

Just the job, does it come on with the origional jet then or switched independantly?.

Using the relay as suggested it comes on with the original jets - but I am going to have an override switch on the dash (like you would have with spots that come on with the headlights) because frankly, they are a bit over the top for normal road use :D
Can't wait to try them in mud though!
