I think you're right. Your '90 is different than my '87 which is mounted at the right rear of the engine compartment and easy to get to. When they went to ABS in '88 or '89 they had to move some of the things around and the wiper fluid bottle was one of them.
You might have to take the right front tire off and screw a few retainers to access the bottle. I know my charcoal canister is up there somewhere.

 

It is stuck into the top of the washer bottle, item 1, OB! Wheel off, baffle off, nothing for it.

Hi Greg

Cheers!

I guessed it might be something like that, a Total PIA Job, as I know you know but as you say there's really nothing for it.

Just so I don't have to do the Job Twice, how would you go about fault finding it or should I just buy a new Sensor.

Though now I have got a Plan 'B' as since I removed the Siren from the Car Alarm that you would need 10/10 hearing to be able to hear.

I have now freed up Acres of Space by the Brake Pump to put a Bottle in there, as I never take her out even if it looks like rain and only really need it to pass the MOT.

In reality I think I've used the Windscreen Washers Twice in the Past Two Years but I always have the Windscreen Polished Sparking Clean before every Trip.



Plenty or room for a Windscreen Washer Bottle and there is even the old bracket from the Car Alarm Siren that I removed to attach it to.

 

Good idea, OB, but I have a theory with the XJS. if yo do not fix things as they go wrong, pretty soon the car gets away from you. The sensor could be the looms, the connector, who knows. But in your place I would fix it, compared with the other stuff you have done, it is a cinch.
Greg

 

Never touch a running system and don't interfer with factory setups... Unless something has gone wrong!

 

Hi Greg

Of course you are right.

But I have got into the habit of doing a thorough Pre-Flight Check, every time that I take the Car out.

Radiator/Oil/Brake Fluid etc (this is on my grey XJS) but the same will apply to my red one, when I get her back on the road.

But with that Closing Panel that is behind the Road Wheel, those plastic rivet 'Thingys' never go back as well the Second Time.

And the last thing you would ever want is to have that coming adrift and catching the Wheel when you are driving.

So on Balance of doing the least amount of harm, I think that I would rather disconnect the Sensor, as I know the Windscreen Washers are Working and I always carry a gallon of Water.

Just in case for some reason. I need to top up the Rad which 'could' also be used to Top Up a Windscreen Washer I almost never use.

If It was the something to do with the Rad or the Brake Fluid, then that would be a totally different story.

Is there a wire to the Washer Bottle Sensor that I could disconnect, without taking the Closing Panel apart?

This is one of those few times when I feel that cutting a corner would be a good thing, rather than to have to risk damage to a much more important component.

ie The Closing Panel, which never goes back as Securely, as before it was taken out.

 

If you worry about them "jamming" in your wheels... Don't. My XJ8 has the same covers and the left one has rubbed away after rubbing against the tire at >125 mph...

 

Hi Daim

That is exactly what I don't want to happen!

 

I don't really care about it Old cars do that kind of thing

 

Hi Daim

You are Normally such a perfectionist, so that has to be very the last thing that I was expecting to hear (Lol)

But everything was working OK until I put her in the Garage and laid her up for the Winter so I may try driving her round for a bit, in case She

decides to Start Working (We live in hope!)

 

Does anyone know what this is?

It backs on to the Windscreen Washer and seems to have a Tube of Water coming out of it.

Could it be the Sensor that Controls the Low Warning Light?



What does this little box do?
Its Screwed onto the inner wing/fender and on the other side of this is the Windscreen Washer Bottle.

 

If the tube contains water, I imagine it is the water feed to the washer jets OB! Got to get pumped out of the reservoir somehow!
Greg

 

That little box? It is connected to the alernator. I think some kindof anti crackle box ...

 

Hi Greg

There are Two Pumps on the side of the Water Bottle, I know this from replacing one of those Pumps on my Red Car.

So maybe this Box is a Switch to turn on those Pumps, if that's what you meant?

And although I might have to eventually undo that Closing panel, it was Working OK before I laid the Car up, so maybe the Float or whatever it is

has got stuck and Calciumed up, so when I re-Tax her in March or April.

It might pay to drive her around to see if she clears.

 

Hi Daim

Not sure you are right on this one, most likely controls the Windscreen Washers, like Greg said.

 

Are you taking about the little black box? If yes, then no. I am right as it doesn't connect to the washers. I removed mine clean Ing the engine bay out... No connection what so ever to the wiper or washers system. Why would it be connected to the alternator if it was?

 

Hi Daim

There seems to be a water tube going into that box.

Apart from that I have no idea what it is or what it does.

 

That's the load dump module. Part of the charging/ alternator system.

 

Hi Baxtor

Cheers!

Now we know.

Looks like you were right Daim

 

Hi Daim

With my first Assistant Director now back on location, we have Shot another Video but did not use the Potato for filming this time.

We Filmed it live in just One Take, so what you see in the Video is exactly what happened.

No Editing and No Jump cuts and just for fun we really upped the Anti and made it much more Challenging this time.

So if you want to see what happened, check it out
