[xj] 0 vdc to the wiper fuse? and Haynes diagram sucks

Where does the wiper fuse in the main fuse block get 12v?
I’m guessing from the ign switch? Can someone tell me which
terminal and what color wire? Haynes manual has wrong color
wires noted and not so sure the actual diagram isn’t wrong
in some places. …real manual on the way.
Thanks,
Bill–

From pin 87 of the load relay.

The relay is activated via the igniton switch but the power feed to
pin 30/51 is a direct take off from the battery. The power feed is
brown and the output to the fuse should be white/pink.–

Haynes don’t sit down and draw their own diagrams, they use
the manufacturer’s. Sounds like you’re getting a bit
frustrated and blaming the tools.
As far as I can see the heated rear screen is on the same
ignition auxiliary relay. Does that work? If not it suggests
a problem associated with the relay.
Thin(ish) white/pink and black wires go to the relay coil,
brown is the battery supply (from firewall stud?) and the
thick(ish) white/pink is the supply to the fuse.
Are you sure it’s not just a bad connection at the fuse
box?
Have you checked for voltage on the cable terminal rather
than just the fuse clips?–

Dave,
The reason I criticised the Haynes manual is because it
showed the supply from the fuse as a pink/wh wire (like you
said), in my car the supply wire to the switch is blk/grn,
couldn’t move the fuse block out far enough to see the
wiring on the back and I try not to tug too much on lucas
wiring as a rule.
And no, I’m not getting a bit frustrated, actually perfectly
calm as it’s my play toy Jag and it’s mostly a pleasure to
work on it. And I’m smart enough to know when tools are at
fault, do you work for Haynes or something?
I do however very much appreciate your information. I’ll
have another look at the haynes, I certainly could have
overlooked something. I did see that supply was common with
the rear windscreen heater, off the ignition relay. What
threw me was no color indicated at the wiper switch harness,
it probably changes colors at the relay or the fuse. I tried
to check the terminal ends on the fuseblock but it looks to
have never been disturbed and rather than risk tugging the
fuse block out where I can get to the back (it’s pretty
tight) I’ll work back from the relay side. I need to find
the relay first…

Black and green as an ignition supply? Either you’ve got the
wrong wire or someone’s been changing cables. Black would
indicate an earth wire, the trace would show it earths
through a component (switch or whatever) so that’s not
right.
White is unfused ignition supply, the pink trace shows
it’s not the primary ignition supply (coil etc) but is the auxiliary ignition supply (radio etc).
There’s a thought. Not just the ignition switch playing up
is it?
No. I don’t work for Haynes :-0 I just think they get a
lot of ‘‘bad press’’ when it isn’t called for. Having said
that, I can’t confirm or deny that my copy of the USS
Enterprise workshop manual is 100% accurate…–

Wise precaution, sir - but if it doesn’t stand it; remedial action is
required anyway…:slight_smile:

‘Unfortunately’; the Haynes diagram does not show the colour change
after the fuse - nor does the Jaguar workshop manual’s diagram. The
correct colours are white/pink to the fuse (from the ign protection
relay) - and light green from the fuse to the switch…

As commented by Dave; the Haynes diagrams are just blown-up copies of
the Jag originals. And when using diagrams generally; some
circumspections are healthy - the diagrams are not 100% reliable. And
further, due to PO machinations odd connections may occur - adding that
in some areas; fading colours and lack of access may be deceptive…

In Jaguar wiring logic; black/something implies a connection through a
user to ground, but it is not entirely consistent - hence the need to
study the wiring diagrams closely. And for serious work; you need to
download the ‘S57’ diagram…

And honestly; not getting frustrated when working on car electrics
indicates that have as yet to delve deep enough…:))

Dave,
You’re right about Haynes getting some bad press, and that
probably influenced my irritation at there not being a
complete color path in the manual, as I remember reading
posts here to that effect. Sorry for being a little
defensive. I have a BMW, an XKE, 2 XJ6’s and a TR6 among
some others most of which I have Haynes manuals for, and
actually tend to use them as much as the factory manuals,
especially for quick references etc… I shouldn’t have been
so quick to pass judgment.

The Haynes are extracts aimed at the DIY, Bill - and as such well covers
the topics treated. The workshop manuals are professional tools - and
assumes that the user knows what is what. As charcterised by: ‘Refitting
is the reversal of the above procedure’ - which is not always that
simple…:slight_smile:

I understand about the manuals Frank. The XKE factory
workshop manual is one of my favorite reads, and in thinking
back I can’t believe I’ve been using that book since I was
about 16 yrs old! Scary how time passes.
Now tell me, what is the S57 diagram? I sure hope it ain’t
like a sky hook or a stud bender…(sounds kinda fishy)
And also, I didn’t say I’d ‘‘never’’ been frustrated when
working on car electrics, just not in this particular
instance. I had a car stereo shop for 10yrs in the 80’s, and
did bench repair on all sorts of electronics during that
time, and I’m now a low voltage contractor since '92. So
I’ve been in pretty deep, and I’ve most definitely been
frustrated!! :slight_smile:

It’s the ‘complete’ wiring diagram, including items’ locations, Bill…

‘My’ version is marked 1988 for SIII and xjs, but it is useful far
beyond that. I downloaded it years ago to a memory stick; 11,5 Gb in
Pdf, Acrobat - but I have completely forgotten the reference for getting
it, but it will be worth your while. Someone on the list will advice…?

If you want frustration; take on recalcitrant electrics on a Lancia Beta

  • they must have invented the ‘darkness’ used by Lucas…:slight_smile:
