Chaffed wire.

I talking about a wire carrying "+" voltage that is shorting out. Could be anywhere along the line between the breakers and the motors.

But before you go on a wild goose chase let's clarify a few things and perhaps narrow it down

Which side isn't working?

If you use a fuse instead of a breaker will it blow instantly as soon as the key is turned on? Or only if you operate the switches?

Passengers' side (US auto); uses the flat relays. I have tested the motors - they work; windows currently up. I have tested the switches - exchanging them with the driver's side - they work. I have replaced the circuit breaker (round thing) with a brand new one.

As I have owned this XJ6 for 24 years and an 86 XJ6 for 15 years and about 20 XK-Es over time - I am acquainted with Lucas' wiring and the peccadilloes of them.

Now..... when I put the relay back in, all it does is click. Have wanted to put the driver's side in but fear it may blow and then..... I did go out and purchase a 30 amp Corvette relay - upon installing and turning the key - smoke in the cockpit - coming from the switches....

So........ Many thanks Chuck

 

Thank you for your thoughts - and I took the Master switch into consideration except the driver's side windows work; the passengers' does not. We will see.

 

First, let's get on the same page regarding nomenclature.

The window relay (singular) is round





The circuit breakers (two) are flat:






If clicking and smoke occur when you plug-in a circuit breaker...but without operating the window motors.... then you have a short circuit.

On the basis of "ya gotta start somewhere" I'd unplug all the switches and see if the clicking goes away. If it doesn't, then you have a problem upstream of the switches.

More later. I'm on my first cuppa coffee

I am not having any power on the brown wire ,, oops what to do

thx in advance

 

I had the same issue. Located the relay and it was dead. Checked at least 10 local auto parts shops and none could supply a replacement. In the end, I got a pack of 10 on Amazon. The relay is a standard generic 12V 30/40 Amp 5-Pin SPDT relay. See link below.

 

Hi sir, my jaguar 1986,sovereign, used to be my uncles. And all the electrical and items were in buckets and I ve spent years fixing everything back.70% of it done. My issue is as mentioned above my black/pink wire which should be ground is always 12v. Can some one please explain what i might have screwed up. If I give that wire ground supply and the yellow ground lock out switch ground it works. I am hesitant to do that since I want it to be correct as it can lead to other issues.

Thank you in advance for your help

 

A big thanks for this! I have a copy of the genuine/green workshop manual and page 86-11 states and shows that the window relay is on the LH side of the dash! There are a few relays there, but not the one for the windows. I thought I was going mad!

A faulty old Lucas relay was my issue. A new Panasonic piece has replaced it. Windows all work now!
