Kevin.payne.15 Posted January 14, 2018 Report Share Posted January 14, 2018 Guys thanks lot for helping me sort the wiring. I’ve started stripping out today with the method that a brake one connection and replace it with the new one. Was doing quite well until I came across this component located on the off side near the fuel inlet looks like mr bodge has been here before me ! Component markings are Lucas England. Top II RA on the little round boss. As you can see the wiring is a complete mess with everything going into connectors bypassing the unit so can only presume it’s not working. Is it a night dimmer ? does anyone know : A what is it if not a night dimmer B how do I test if it’s working C where do I get a replacement if it’s not? D how do I wire up the new wiring loom at this point has 2 reds wired together, 2 green purp wired together, 2 blacks wired together, 2 green whites separate, 2 green reds separate and lastly a green purple = 11 wires in total going into 9 connectors with 9 spades on the unit thanks kevin Link to comment Share on other sites More sharing options...
Gully Posted January 14, 2018 Report Share Posted January 14, 2018 Yes, that's the famous night dimming relay. Delete it! Part reference is 159716 late or 216112 early - see plate 05-79 in the parts manual. Gully Link to comment Share on other sites More sharing options...
Pete Lewis Posted January 14, 2018 Report Share Posted January 14, 2018 And a wonderfull array of those blasted scotch loks The normal bypass was to join all likes together and drop the earth Or just drop the earth but with that bunch of bodgeroonies its been done the hard way Pete Link to comment Share on other sites More sharing options...
Kevin.payne.15 Posted January 14, 2018 Author Report Share Posted January 14, 2018 Presumed it had to be. What does one do with the green purple single wire? Currently on the old unit has the two reds going into one spade with the black on the other is it not easier to refit a unit? kevin Link to comment Share on other sites More sharing options...
Guest Posted January 14, 2018 Report Share Posted January 14, 2018 Hello Kevin. The green purple should be stop lamps to stop lamp switch - what is the current wiring situation coming from the STOP LAMP SWITCH ?? I think the 2x reds can be joined together as the dimming unit acted as a junction box performing a specific task of which the red would have required splitting to form a circuit to incorporate the dimming relay circuit. This is me just thinking aloud at the moment. Does the above suggestion appear feasible ?? Regards. Richard. Link to comment Share on other sites More sharing options...
Pete Lewis Posted January 14, 2018 Report Share Posted January 14, 2018 These relays just dimmed the stop and rear flashers wjen the side lights were turned on Just get some double ended lucar blades and join all the same family of colours together Red to red and greens to greens , just match the colours and join them Dump the black and bin the unit It was a good idea in its day but now going to be some trouble Dim dip headlamps had the same short existance Petel Link to comment Share on other sites More sharing options...
Mjit Posted January 15, 2018 Report Share Posted January 15, 2018 A what is it if not a night dimmer It is - and it's pointless in modern traffic. B how do I test if it’s working These almost never fail (in a bad way) - you just need to check for continuity between pairs of in and out pins. C where do I get a replacement if it’s not? If it's actually failed so you don't have any continuity then delete it, linking like wires directly to one-another. D how do I wire up Would have to look to say (and I'm currently 400 miles from my car) but once you have pull the black earth lead. Looks original but as no earth switching on the side lights can't complete the circuit so can't energies the coil and can't dim the lights (which were hardly like looking at the sun when new, let alone 40yrs down the line when all the silver has come off the reflectors.

As for dimming rear lights, that is a new one on me and not come across it or heard about it before - so as they say, everyday is a school day Link to comment Share on other sites More sharing options...
Kevin.payne.15 Posted January 15, 2018 Author Report Share Posted January 15, 2018 I’ll remove thanks. i Found a one para reference in acspitfire manual that simply says rewrite in the same way as installed! Really helpful! kevin Link to comment Share on other sites More sharing options...
dave.vitesse Posted January 16, 2018 Report Share Posted January 16, 2018 Though included in the wiring loom of 1970's models not all were fitted with the relay. The Toledo had a by-pass plug fitted instead of the relay. Dave Link to comment Share on other sites More sharing options...
Pete Lewis Posted January 16, 2018 Report Share Posted January 16, 2018 i love triumph manuals they delight in making no comments or script about the one little part you need help with and the idea that refitting is the reverse of not telling you in the first place much of my orig triumph reprint WSM does not cover the changes in MK2 2000 and keeps rambling about MK1 with an odd supplement hidden or thrown in for good measure , never covers the particular area of concern . Im sure they like to keep a few jobs up their sleeve Pete Link to comment Share on other sites More sharing options...

Colin Lindsay Posted January 17, 2018 Report Share Posted January 17, 2018 I once met a young lad, back in the 1980s, who had the letters ADU tattooed across his forehead in light blue ink. I asked him what it was and he very sheepishly admitted that he'd tried to tattoo "UDA" (Ulster Defence Association) on himself in front of the mirror....
