AndyO Posted January 4, 2010 Share Posted January 4, 2010 Hi All, First off - Defender 200tdi (just before switch over to 300tdi) Right - got a confusing problem going on with my headlights for the defender. This seems to have happened since having a roll cage fitted just before christmas (however I cannot guarantee that there was not a problem before!) When I push the light selector to 'side light' position, the side lights do not come on however the main lights come on at ~half power (dim dip thingy?) The main headlights flash when pulling the stick back (as normal) but do not stay on when pushing the stick forward (I don't know if this is normal as I have never tried it on side lights only!) When I push the light selector switch full forward (main beam not full beam) The headlights go out, but the side lights come on. Then the full beam selector works in both directions (flash & fully on). So, any ideas from the group. Earth wire got dislodged somewhere, could the dim dip part of everything have gone tit's up? Some wireing got fried during welding? I pulled the fuses but they all seemed fine. I've had a quick wobble of wires but as its cold and not a priorety I have not investigated fully yet!

Cheers Andy My Defender doesn't have dim/dip, but it does seem as if you've lost the feed to the dip beams. I'd check the fuse, then look at the switch itself. Sorting out my 1985 CSW I found a problem with a connector on the stalk itself. Cheers Peter Quote Link to comment Share on other sites More sharing options...
errol209 Posted January 4, 2010 Share Posted January 4, 2010 I'd suggest that the main lighting switch is on its last legs. Quote Link to comment Share on other sites More sharing options...
AndyO Posted January 4, 2010 Author Share Posted January 4, 2010 2 for the switch eh. Will have to check that out. the fuses all seem OK so... I have had to replace the rear fog switch & the indicator stalk before so it would make sense that the light selector is going out as well. Maybe I should change the screen wash/wiper stalk while I'm at it!!! At least it gives me an excuse to align my steering wheel properly! (I've been living with it 1 notch out for too long!)

Mo Murphy Posted January 4, 2010 Share Posted January 4, 2010 My vote goes for the switch too, they are prone to all sorts of problems once they start to fry Mo Quote Link to comment Share on other sites More sharing options...
western Posted January 4, 2010 Share Posted January 4, 2010 I'll vote for the main light switch too, try a new one. Quote Link to comment Share on other sites More sharing options...
AndyO Posted February 1, 2010 Author Share Posted February 1, 2010 Hi Guys, Sorry to resurect an older post but don't want to start a new topic for the same thing! Finally got time and fitted a new switch - no change in circumstances! The headlights still both go out completely when selecting main beam. Any suggestions as to what would affect both sides?

western Posted February 1, 2010 Share Posted February 1, 2010 Andy, examine all the wiring near the rollcage bars, I suspect one or more has got caught & is shorting/earthing out Quote Link to comment Share on other sites More sharing options...
AndyO Posted February 2, 2010 Author Share Posted February 2, 2010 post up your rough location in your profile, some kind soul witha meter and some knowledge of electrickery may be able to come and have a butchers Doh - I actually thought I had filled in the Location bit (I've seen enough other people told off for it!!) Will go and update it now. Western - thank for the suggestion. Would this be likely to affect both headlights? Quote Link to comment Share on other sites More sharing options...
Puffernutter Posted February 2, 2010 Share Posted February 2, 2010 I assume that there is a main beam relay somewhere - can you check that you are getting a feed to and a feed out of that. Cheers Peter Quote Link to comment Share on other sites More sharing options...
Retroanaconda Posted February 2, 2010 Share Posted February 2, 2010 I don't think there is any relay, just a feed from the fusebox to the switch and then to the lights. Quote Link to comment Share on other sites More sharing options...
adam300Tdi90 Posted February 2, 2010 Share Posted February 2, 2010 Check feed to and from this resistor. Bolted to the inner wheel arch liner. Should be able to get to it (just) Quote Link to comment Share on other sites More sharing options...
western Posted February 2, 2010 Share Posted February 2, 2010 IIRC the 200TDi Defenders don't have a headlight relay, just wired from the switch/power/earth if a dim dip unit is fitted, it can make strange things happen with the headlights, the unit should be behind the instrument pack, a black box with a rigged face, pull the plug out & recheck light operation, if all is well [except dim dip headlights] you've solved the problem.

Wereabouts would that resistor be? I've had the pass wing off & apart before and I don't have one (and the above pic looks like that area). I've heard mention of the dim/dip relay before. is it just a case of pulling the connectors out of it, or do the two ends (so to speak) need to be connected.

western Posted February 3, 2010 Share Posted February 3, 2010 look on the drivers side wing inner rear edge. if you have that resistor & a pink bodied relay, IIRC 2 of the relay wires need to be connected to gain normal headlight operation.
