Alpha206 Posted August 2, 2014 Report Share Posted August 2, 2014 So I'm driving home from the pub on Thursday, country lanes so I put the main beams on (floor-mounted dip switch, fitted 2006 and not used that much). Car coming the other way so I dip the lights...except they go off. Instrument lights are still at full 1-candlepower.Hit the dip switch again and main beams come back on, cycle the lights lever on the column and hit dip switch and dipped lights back. Sigh of relief breathed. Get home safely (touching nothing!) and have play around whilst putting the car in the garage - no mains/dips. On further investigation I've found that all other lights are working, but the sidelights and tail lights only work in the dipped beam position, and then only after waggling the switch a little. So, I guess the question is where do I start finding the the fault? Foot switch (on which I've checked the connections in case I'd dislodged something or column switch (my thought is the latter) - anyone experienced these symptoms before?

Marc R Posted August 2, 2014 Report Share Posted August 2, 2014 (edited) Hi Greame, The Dimmer switch (Floor mounted for you) must be wired between the main Lightning switch and the Low Beams & High Beams, his way to work is just to switch from Low to High beams and reverse. One hypothesis is that the wiring and/or connection from the dimmer switch to the Low beams is/are not correct and/or disconnected. Start at the Dimmer switch side to check if you have wires on the 3 connections. Colors U (Blue) to the Lighting switch , U/W (Blue/tracer White) the High beams and U/R (Blue/Tracer Red) to the Low Beams (At least it should be this colors arrangement for the TR- '72), but to be confirmed. You shall check the way the Dimmer swith is connected! Did you have the wiring diagram? Kind regards Edited August 2, 2014 by Marc R Quote Link to post Share on other sites
Malcolm Tatton Posted August 2, 2014 Report Share Posted August 2, 2014 Had the same on the way back from the Quo concert after CPOP. Mine was a poor spade connection on the dip switch. Removed the switch, cleaned it up and it's been fine since. Quote Link to post Share on other sites
Alpha206 Posted August 2, 2014 Author Report Share Posted August 2, 2014 Hi Mark, the dip switch has worked fine for the last 6 years so it's unlikely to be incorrect wiring. Malcolm, have cleaned the terminals but will try and do some more work on the connectors...thanks for help so far! Quote Link to post Share on other sites
Marc R Posted August 2, 2014 Report Share Posted August 2, 2014 @ Alpha206, Correct suspicion on connections/connectors side, have a look at 1st on the connection to the Low Beams side. As the issue is on the both 2 Low Beams, check on the dimmer switch side but do not forget the connector Female Double line 4 ways, common contact on the low beam side . I just worked on this area this afternoon. Kind regards Quote Link to post Share on other sites
