Thank you Dave, I'm really pleased you agree they are the headlamps in the photo on the Royal Barge. I'm glad they are the originals, maybe Volvo just fitted them for one MY? As I said earlier in this thread they are not (IMHO) a very clever design in that the only way of removing them is by unwinding the adjusters all the way (and hence losing the alignment) - also they have no horizontal alignment adjustment. Maybe Volvo realised they were not so clever and changed the supplier for 1981?

Best wishes,

Alan

There might be an easy way (not immediately obvious) of releasing the headlamp without distrubing the alignment Alan, likewise there might be a hidden adjuster for the horizontal adjustment as it would have been a requirement of the MoT to have that adjustment. Look for a "D" shaped cut-out in the bezel to see if there's a horizontal adjuster somewhere.

Possibly done for one MY only or maybe only part of it or perhaps just an option instead of the older round headlamps or newer square headlamps.

Just to put my tuppence-worth in on the headlmps question: back when I was a Scottish resident there was a local-to-me "W"-plate 244GLT in maroon that had the large rectangular headlamps. It boasted a steel sun-roof and a B23E engine with a 4+O/D box. I suspect that Erik in the parts store at Gothenburg doled out whatever came to hand for the UK market - North America was very strict on what could and could not be fitted and the continentals tended to be uptight about specs as well, whereas we took whatever was going...

On a separate note; if you're doing regular oil changes it's worth getting a second sump-plug for the Royal Barge (I do like the name) so you can retrieve the original from the catch tank at leisure, but beware: some aftermarket sump-plugs are 26mm diameter. I know because the one I've got is!

Accessory lamps
 

The Triumph (bike) was sorted out for tomorrow's MoT in half an hour (I keep it pretty well maintained, but I always allow myself a day just in case), so I thought I'd tick another job off for the Royal Barge: the driving and fog lamps.

Regular readers will remember that all 4 lamps were operated by a horrible switch stuck onto the dashboard. I started there and found an always live feed, which worried me a bit:

I traced the live back towards the battery and found it connected to what I suspect was some sort of power supply for a ICE system (long since removed):

So, the switch was connected directly to the battery. I traced the other wire from the switch and found it was connected directly to the first driving lamp, from where the other driving lamp and two fog lights were connected in parallel - so 210W or 17.5A running through a series switch inside the cabin without a relay in sight. It is fortunate that a PO had not set fire to the car. I got rid of the switch and nearly all the wiring, just leaving the permanent live for the radio (I know that doesn't need to come direct from the battery, but it is safe and I'll tidy that bit up another day):

I removed yards of wire, ducting, lots of chocky blocks and tape - as well as the two fog lamps:

All the lamps were connected to a single (puny) earth lead (which may have been the one thing preventing a fire by restricting the current):

I've just left the two driving lamps, which I will wire to the main beam harness on each side of the car (but that is a job for another day - it has started raining and Dan and I have to take Bob to the vet for a check-up this afternoon). I think the Royal Barge looks a lot better without the fog lamps, and also without the wing mirrors:

Well, a good two hours work - at least the car electrics are safe now, and I know how the car was wired (wrongly). I'll probably get the driving lamps wired up tomorrow after the Triumph's MoT; I'm not sure about the fog lamps, I can't think of many times I've ever actually needed them in a car and I'm not sure there is really room for them.

... another unexpected consequence of something I've done to the car (I'm not sure which job it was) is that the left side headlamp wiper has fixed itself - I just need to adjust its park position now.

Alan

I see your point about the sump plug, the oil certainly comes out a bit quickly (it caught me unawares as it exceeded the rate at which the catch can would drain).

:-)

Bob
 

The really good news is that the vet is very happy with Bob's progress. the sepsis has gone, as has 90% of the swelling on his foot. He can start going for walks again.
:-)

Wouldn't be surprised if the extra lights were earthing through the L/H headlight wiper motor Alan! :eek: :err:

If you move the driving lamps above the bumper it'll make the wiring easier and i don't know about you but i've seen some nasty fogs round Corby (long time ago though) and like many things in life, it's better to have them and not need them than need them and not have them!

I'd reposition the fog lights so the centre of them is in line with the centre of the headlights but under the bumper, if you were to put them where the driving lights currently are, they'd be under 600mm apart so would be illegal - strangely this doesn't apply to driving lights! :err:

Great news about Bob! Need to take my pooch soon, she missed the weekend walkies thanks to Dennis the Menace and missed yesterday thanks to me twisitng my back and barely being able to move!

I hope your back is recovered Dave.

I see your point about the driving lamps - putting them above the bumper is a possibility I had not considered. Also it would give a bit of room for the fog lamps underneath. They would have to come in a bit to make room for putting the car up on ramps, but it would not be a difficult job, and I suppose I have almost everything I need to do both jobs save for a tenner's worth of relays and bits. There is even a spare switch for the front fog lamps. If I get time after the bike MoT tomorrow I'll mock it up and see what it looks like.

Bob is looking forward to a proper walk this eve, he has to wear a special dog boot I got him to keep everything clean:

It's calmed down to a just-tolerable but still deafening roar thanks Alan, a few more days it should be down to its usual dull roar i hope.

Hope Bob enjoyed his walkies, seeing him reminded me of two things - 1) the song "Three wheels on my wagon" and 2) my old Rusty who went to the great dog park in the sky in July 2017.

He was a rescue and i'd had him about 12-13 years when that pic was taken, was told by the rescue centre he was 18 months when i got him but closer inspection suggested more like 4-5 years old.

Thoughts on the front fogs - you have the switch there (a genuine one too) so would be nice to use it. Perhaps in the fullness of time find the Ring Microline front frogs that match the driving lights and are very similar to the OE Bosch/Volvo lights.

Hi Dave,

Yes, Bob is a bit of a 3 wheeler at the mo, he is almost recovered though.

Rusty certainly did well - I hope I have Bob that long (I'd be a bit lost without him).

You may have been right about the previous lighting setup earthing via the left hand headlamp wiper motor - it is really odd that it started working (it was one of my 'fix one day' jobs) as soon as I removed the wiring.

You are probably right about the lighting- and using the genuine Volvo front fog lamp switch. I quite like the idea of the lights - they just need installing properly. What I will do today is remove the driving lamps from under the bumper and we will start again from scratch. I'll find the cable ends that come from the proper fog light switch, acquire the bits and pieces you suggested for the control circuit in one of the posts above, and execute a proper installation for both sets of lights. This can wait a bit, there are a few other jobs to do first.

I think I'll have a look at the instrument illumination next, plus see if I can fix the rev counter at the same time.

Best wishes,

Alan
