Hi Webserve and all!
(he gets a special mention as he's usually got the answer). More on my
1988 XJ40 (with digital instruments and oblong headlamps). Have just
bought two plastic headlamp protectors form Jagara here in Sydney. The
headlamps cost $200 each and are easily smashed by flying stones. The
protectors clip on and cost me $75 the pair! Also, on Webserves advice,
have got a spare crankshaft timing sensor. Next problem, missing puddle
lamp RH rear cover. This is a bit of coloured plastic. I thought the
rest of mine were red but Jagara has sent me grey (american = gray!).
Could all Xj40 owners be very kind and tell me what colour their puddle
lamp covers are?
Are the colours different for RHS and LHS, by any chance?
Suggest you try H&H Prestige parts in Melbourne on 1800337379. Speak with
Herb or Phil they can answer your questions and should be able to provide
the part within 24 hours (when I needed new shocks, all the locals said two
to three month wait, I rang prestige and had them the next day). Their web
My 87 Sovereign's puddle lamp covers are all red.
Update for all contributors re puddle lamps. The Prestige firm in Melbourne,
recommended by two of you, were indeed most helpful and solved the problem
immediately. The puddle lamp covers *are* smoky (grey) but you never see them
smoky as when the doors are closed, they are practically hidden. When the
doors are open and they come on they show red, because *there is apparently a
red diffuser underneath the (smoky) cover*. So I had got the right cover but
needed the diffuser too, which Melbourne are posting to me.
Then I'll tackle the no-lamp-on problem, which I have described earlier. Brief
summary of *that* problem. Puddle lamp doesn't light, but the globe/bulb tests
OK and there *is* 12 + V on the contacts. First diagnosis by me: computer.
Advice from contributor: computer not connected to interior lamps. Second
diagnosis by me: high resistance joint in circuit - when meter connected
negligble current drain so 12 V indicated. When lamp connected, high current
drain introduces large voltage loss across high resistance in circuit. I still
favour this one. However, I have a second theory now. High resistance in the
*interior* of the connection. Meter probe is to the exterior. Same results as
before. Will investigate further and report.
Original query. Confirmed the quiescent current is 50 mA, which should not
discharge a *good* battery if car used at least once a week. BTW, Prestige's
Phil not quite right here. He thinks the Q current is normal but due to many
capacitors in circuit - in fact (non-faulty) capacitors should not pass *any*
current. But it is probably the conmputers, of which there are a few. Can
anyone else who's savvy please check their Q drain. I believe mine is normal
but would like to know. CAUTION do not do this unless you know what you are
doing with electricals, batteries, etc, and ensure connections are later firmly
restored. BTW, you need an analogue meter because there is a pulsing on the
line from the clock, which will cause a digital meter to read very erratically.
Is there a justification for forming an XJ40 newsgroup? Are there many XJ40
users out there?
Thanks to all
Just checked on my 87 3.6 Sov but I am not removing to see what is on the
inside. Firstly the lamps are two tone plastic, clear underneath the lamp
giving a white light downwards and red light to the sides. Definitely red
when the door is open and the lights are on but when the door is closed and
lights off they look more of a dark plum colour. Really do not look grey to

Thanks for your reply. See my earlier message updating progress. I've learned
that the outer cover is smoky but there is an inner red diffuser. I guess with
the lamps off the diffuser would show through the smoky to give a dark plum
colour. Waiting for the diffuser via the mail (today?) and will report.

Dave Manners is pretty good, they really know their stuff and can be found

A sunny Sunday, not too hot or too cold, peacefully working on the XJ40 on a
non life-and-death improvement, far off the road. What could be nicer?
The promised update for all those who helped with my puddle lamp problems.
First, easily dealt with, the colour: It turns out that the smoky grey
cover is correct, but inside it is a red diffuser, which is screwed to the
door lining. All is OK.
Now on to the non-operation of the lamp. You will recall that the bulb
worked and there was 12V measured on the springs, but the bulb didn't
light. I finally decided that the meter read 12 V all right because
although there was a high resistance fault in the circuit, the low curent
drain of the meter (digital - very low) gave no voltage drop across the
fault. But when the bulb (globe) was plugged in, the attempted current
drain led to a very high voltage drop across the fault. Well, much
dismantling later, and using needles to penetrate wires, I traced the fault
to a little PCB under the door switch module. The earth to the puddle lamp
goes in and out of that PCB and that's where the problem was. It turns out
that a diode in circuit (1N4007) was high resistance (*both* ways!). I'll
order a pack of them (1 only is an unworkably low price!) and fit it in due
course. The only downside is the back seat of the car is full of bits and
screws that had to be taken off. Virtually the whole of the door linings
and all fittings had to be dismantled to get at this 1 cent part! Still, it
wasn't raining down my neck. (I remember changing the big ends of an MG TD
lying on my back in the snow in the street in freezing cold England, years
OK Webserve! Actually my air-conditioning is totally inactive at all speeds,
but that is another story and lies ahead. Before I was ill I remember fitting a
new microswitch in the dash controller but not the detail from memory, except
that it's a common problem. This one seems to be different. BTW, have bought a
packet of 100 1N4007 - is that enough, do you think? <g>
OK. Now I have another problem!
Found the faulty diode on the PCB and replaced it. All tests OK. Then put the
PCB back into the moulding, and another test shows the electric window winder
(connections are on the same board) working in reverse. So obviously have put
PCB in the wrong way round (it appears identical so it was a 50/50 chance! I
lost!) Now, I cannot get the old PCB out of the moulding, and can't see what is
holding it in. Any experience of this anyone? I've taken out the two little
screws, but the PCB seems stuck fast even after trying it in the freezer.
OK all. Got it! The PCB is actually secured by a little springy plastic tab
is hardly visible. Push that in with a fine screwdriver and the PCB comes out
easily. Thank goodness I didn't do any damage with all that previous heaving!
couldn't even spell "expert" and now I are one!..
I think that'll probably do before my move on 28/9. There I have a nice big
workshop and things'll be a lot easier!
Standby for bulb warning light progress, and then air not working at all. No
anything. Must be elctrical and at least I have a good digital multimeter for
(and 90 odd 1N4007 diodes!
Greetings to Webserve and all
Done the snow thing as well. Mine was a late 50's sit up and beg Ford Pop
with an E93A side valve engine. It must have been 1969 when we swapped the
engine out with one from a scrappie at a farm opposite the Highwayman pub
about 5 miles out of Macclesfield (Cheshire) on the road to Buxton. It was
January, we were working outside and me and my mates finished at about 2.00
in the morning and everywhere was white. It was so cold we had to wrap up
the spanners to stop them freezing. Much to all our surprise it started
The 'good' old days - at least cars were easier to repair then.
OK. The promised update. The problem *was* the 1N4007 diode in the window
switch module, which also has the puddle lamp earth going through it. But first
a red herring. Soldered in a new 1N4007 and tested it - no joy. Must be diode
the wrong way round. Soldered in the other way round - still no joy. Realised
although earth return is via small connector, main supply is via big circular
connector (for the windows). So resolderd diode other way round again and now
tested properly - success! Diode stripe (cathode) must be at top. Now to go
out on sunny day and reassemble all the door trim.
