series 3 sovereign, workshop manual, high beams and coil
Hi all,
Recently bought myself a series 3 sovereign. Happy me.
Couple of quick questions thought,
High beam..... When I first got the car, high beam came on by pulling the stick, but only stayed on whilst holding. Now no high beams. Fuses and relays test OK. Is the stick supposed to'lock on' first pull and go back to low beams when pulling again? Maybe I need new switch?
Also, coil just crapped itself, multimeter confirms. Whilst waiting for a genuine jag one to be delivered, 4-5 weeks, can I use an aftermarket one? I'm thinking Bosch su12r.
Finally, I want to pull the timber dash out to re apply new veneer, does anyone have a link to a full workshop manual, not just the basic one like Haynes.
Cheers

which Headlight fuses are you checking? There is a 5-fuse fusebox near the radiator-coolant tank, it contains a fuse for each headlamp and the fifth fuse is for the automatic auxiliary electric fan, seen under the front bumper, check those fuses if you haven't already.
get the 12-cylinder Coil, SNG Barrat has them in the USA store. Doug knows the part number, I always forget but that one is what I have in my 6 cylinder. SNG has free shipping this week. SNG Barratt - The Ultimate Jaguar Parts Specialist
what year is the car?
if it is a Series 3 6-cylinder, the Service Manual and the Parts Manual are in the XJ6 & XJ12 'HOW TO' quick links at the top of the forum page.

Jose is correct, first thing to do is check the headlight fuses as he described
Here's more info on headlight problems
Headlamp Circuit Checklist
If you have the 4.2 fuel injected 6-cylinder I recommend the Lucas DLB170 coil. But, any 12v coil with about 1.0 ohm primary resistance will be OK.
Jaguar service manuals are usually out there on Ebay or from Jag parts specialists. But, even though better than Haynes, the 'factory manual' is far from perfect You'll also want the "S57 Wiring Guide" which you can download from this site. Go to the "How To" sticky thread at the top of this section

BJ;
It would be nice to use your name and location. I'm AKA Carl.
Fuses in these cars can be confusing. My old tech idea of a careful visual to see it the frangible link in the glass was intact or interrupted does not apply. The fuse may pass a visual but flunk a continuity check with a lamp or meter.
The fuses may respond to a finger roll in situ. An interesting phenomena I discovered.
The connections under the box Jose referred to may need a scrubing to restore continuity.
But, unfortunately, the symptoms you describe imply an issue in the Hella relay located by the fuse holder Jose wrote on.
And, the S57 publication is a must. Electrics is not my strong suite, but the schematics there are amongst the best I've ever seen. Helped me a lot over the years. Thanks to Bob Loftus. And, I've shared pages with others to help them.

Jose,
It's a 1984 sovereign, right hand drive and the fuse box you mentioned had been replaced by the last owner.
It's now got 6 fuses, 5 are 30amp and 1 is a 35.
And I've checked the links, thanks heaps.
It is looking like the big expensive hella relay. Plus the fog lights don't work, but I'm going to swap them out for LED spotlights as I live in rural Western Australia.
But to turn on and off the high beams....
In my other vehicles, pull the lever on the column and high beam comes on, release and it goes off, only on whilst pulling towards. To turn them on, push the lever on the column and they stay on, the lever clicks into position and stays slightly forward, pull the lever back to the centre position and high beams off.
In my jag, you can't push the lever towards the front of the car, and when pulled towards me, high beam no longer works (relay) but did when I got the car. Release the lever, high beams went off.
Hope this makes some sense

in the 1984 XJ (whether Base / VandenPlas / Sovereign), you pull the lever towards you and you can hear a "click, but the Lights Switch needs to be in the Headlights ON position for the high beams to STAY ON. Otherwise with Headlights switch in OFF position, the lever works as a "flash-to-pass".
Those Hella Relays are super reliable and long lasting, my 1984 still has the original, but yes it could also be the Relay.
To turn the Fog lamps on, I am sure you know that you need to push-in the Lights switch knob when you get to the fog position at the switch.
Roll the fuses like Carl said, one by one, ideally with someone else clicking the lever while you do it. Also if you did the Checklist that Doug provided, you will find the culprit. You can get a used Relay if it comes to that.

Phoeey, A script error message dumped a good post.
1. Fuse box gone. Fussier inline fuse holders replaced it.
2. Blade fuses would be better.
3. I miss floor mounted "dimmer switches.
4. Larry Hooper Of the old Lawrence Welk show sang a tune in his deep bass that fits here, "Oh Happy Days".
Truncated version of lost post.

Fog lights now working.
Only had to completely rewire from the fuse box as the last owner has neither brain nor mechanical skills.
Almost a given it's the hella relay, after all, when your windings are fried, you don't relay and neither does it.
Starting on coil wiring today as it's gotta be done.
Now to find someone near me who has one of these lovely ladies.
I'm sure I'll find someone

To answer you headlight lever question.
There is no mechanical latch in the lever. All it does is provide an earth pulse to the headlight relay. The headlight relay has a latching function built in, so pulse it once it switches to high beam, pulse it again and it switches back.
Dont hold the high beams on for a long time with the lever, its only meant for flashing. Its possible to damage the relay.
You can stay original or replace the relay with a generic unit used for a variety of uses from VW headlights to yank tank sunroofs. I did a thread on that a while ago.
If you are playing in that area you might also want to consider putting in a relay so that your headlight switch just operates a relay instead of having full low beam current through it. Its easy to pick up battery of the firewall post to do this. Has the side benefit of improving the low beams , which on mine were about as useful as holding a zippo lighter up as you were driving.
Enjoy your new toy :-)
PS here is the old thread on headlight relay etc https://www.jaguarforums.com/forum/x...-relay-162296/
If you want to stay original I think I have a standard headlight relay you can have (I gave a relay to Clarke, but I cant recall if it was start or headlight now , and I am travelling atm back in a week)

This afternoon is all about pulling the steering wheel off and locating the reason I can only have indicators or the switch for the hazards installed. Crazy yeah, leave the black toggle off and indicators work, click it back in and only hazards. I should have both by later today plus new wiring for the new coil.
Where bouts in oz do you live?

DefaultHi everyone I’ve just ordered a new Lucas Ignition coil for my Jaguar XJ6 4.2L Series 3 and they didn’t send the exact one I ordered, this is the one they sent Genuine Lucas Gold Sports Coil DLB105 Non ballast ignition will it still work or does it need to go back thank you in advance

I wouldn't use it, personally. I did some quick checking and the DLB105 has about 3.0 ohm primary resistance. The correct spec is about 1.0 ohm.
DLB198 is generally accepted as correct for the Ser III 4.2. It has .8 ohm as I recall
I've used the 198 with good results on the Ser III 4.2 although, personally, I've found (quite accidentally) that the DLB170 works better.
The listing/applications for these coils has become very confused and the specs listed seem often to be *****-nilly. I suspect this is a result over many data-base mergers over the years.
Cheers
