It sounds like Roger the Bodger has been at this one. The original lights were all H1 single filament type. The inners were main beam, the outers dip. On dip beam the outers were illuminated, on main beam these stayed on and the inners came on as well, giving four illuminated lights. Although they all used H1 bulbs, the inner and outer lamp units had different beam patterns.

Thanks Dave - I think defo Roger the Bodger or I think probably the company (now defunct) that carried out the resto on this stag in around 2003/4 were maybe OK at bodywork etc but had not a clue about the electrics other than get some wire of any colour and make it work!

Firstly the manuals do make reference to sealed beam units as well as halogens . This car is Sept 1973 - not sure what was original equipment?

On main beam all four lamps are lit but the the sense of the two outers does not change. My secondary point being that the main beam filaments on these outers could also be lit

Hi.
There has been many a thread on this subject, but basically if you wire the lights to use all the fillaments on main beem, the power pull would be too much for the wireing in the car leading to baaad things happening and smoke escaping the loom! If yo want better lights, then use an upgrade kit from one of the suppliers. It would include loomsand relays to ensure the safty of your pride and joy. I recently upgraded mine using a direct feed from the battery, using the original wires to switch the relays, and interupt the dip fillament and use the main fillaments in all 4 units.what an improvment!!!!
I would post instructions, but i am one of those incompetents with the written word and would probably make a disasterous mistake and make stags melt all over the uk.
There are those on here that are much better than me at that sort of thing.

Relays not needed if you go the HID option as they pull less current and are lots brighter.

Hi stagdad.yup agree, but i am a cheapskate and did my conversion for about 50pusing bits i had lying about in my just in case tin.

Thanks to all - yes see your points but could someone please answer my principal question about confirmation of correct connection of SB units?

**Hettiherald** · 18 January 2015, 00:01

Hi
Ihave a pdf of the wiring diagram, but cant get it onto the post. If you search for it on the forum that should help you. If you have trouble finding it, send me a pm with your e mail, and i will send it to you

A pdf of the diagram won't help as it shows the OE quadruple H1 setup. Dual filament SB units have been added to his car at some time in its past.

FWIW here is the section showing the dip/main switch (29), dip lights (28), main beam lights (30) and main beam warning light (31).

Further to my earlier "Unidentified Black box" thread and ensuing headlight problems I decided to examine the connections to all the sealed beam units.

The two Lucas inners (full beam only) are OK but discovered that they were wired with red and black feeds which of course is non standard. Furthermore guess what the

black is live and the red is earth

Took me some time to conclude this with multimeter

Following the wiring back reveals crimp connectors just before wiring diappears into sheathing where (difficult to see) it appears that the correct colouring is restored.

My main question relates to the 2 outers. These are Ring units with dip and mainbeam filaments. In their intended application these should I assume be wired for dip beam only.

My memory confirmed by searches says that on these SB units viewed from the rear with the centre connector uppermost Then:

The LH connector is Earth

The centre is Dip

The RH is main

With my LH (N/S) outer I have no idea how it was connected as the connectors fell off on removal. I have reconnected it as above

When I removed the RH (O/S) outer SB unit it was connected with Earth on the left but RH as 12v feed (i.e. Main beam?) There is also a second independent earth connector in the housing (apparently not connected) Have established that both black wires in this case are truly earth.

We have only owned this Stag for about 3 months or so but it has an MOT dating from only a couple of months before we purchased in which I would have thought any lighting errors would have at least been advisories.

Could forumites confirm that my connection ideas are correct in the context of these Ring units and comment on the correct way that the outer RH(O/S) unit should be connected..

It also occurs to me that these outer units have unused main beam filaments. Why are they just not connected in parallel with the inner main beam units?

Surprising, given a statement you made in another post

Little bit confused here.
The wireing diagram should show the correct way of wireing the light units. The only difference with the car is the redundant main beam filament in the outer units. Trouble with these cars is that over many years bodgers have tried to improve / upgrade using bits that fit, but dont always work the same way. IMHO go back to basics first, then improve from there using the great knowledge of those on this forum. Dont try to add to the original bodge, it will end in tears!!!!

Many Thanks. However I already have coloured copy of the wiring diagram. The wiring on the outer lamps is in the correct colours.The only anomaly being the extra earth wire in the RH (O/S) lamp Housing.

I am looking for confirmation from other members that the physical connections on the Ring SB units is as I list in my OP. Remember I found the RH (O/S) lamp apparently wired to the main beam not dipped beam connector (According to my list)

The wiring for these outer lamps is OK and not bodged and correct according to wiring diagram it is the physical connections to the unmarked connectors on the SB units that I am seeking to confirm.

Surely it isn't difficult for an electrics expert to work out which of the three terminals is earth, dip and main using a multimeter and a 12v supply......

That's how I did it when wiring up my 4xH4 system.
