davie Posted July 24, 2010 Share Posted July 24, 2010 Hey all, Went out last night and realised i have no dip beam in landy, 2003 td5 defender. Been out today and checked bulbs, both ok. tried new bulbs into it and no joy. Have main beam both sides using original bulbs. Been having a poke with meter and get volts at the plug on back of bulb when main beam is on, but nothing at all for dip. Checked all fuses and ok. Any ideas? Thanks Davie Quote Link to comment Share on other sites More sharing options...
Ratty43 Posted July 24, 2010 Share Posted July 24, 2010 The relay would be my first choice. Since the main and dipped have a common earth on the bulb it must be the dipped beam positive, could be a dodgy connection on the relay or on the dipped beam switch.

davie Posted July 24, 2010 Author Share Posted July 24, 2010 tried swopping the relays below the fusebox and didnt make any difference, had a look at switch and no obvious bits fell off - switch is under 6 months old. Quote Link to comment Share on other sites More sharing options...
western Posted July 24, 2010 Share Posted July 24, 2010 have you checked/replaced the fuses ? 10amp fuse 7 in passenger comparment fusebox. this feeds the dim dip if fitted & headlights have you checked the normal main light switch is giving power to the dip headlights ?

davie Posted July 24, 2010 Author Share Posted July 24, 2010 hi western, checked the fuses, will re check again shortly just in case i missed it. how/where do i check this switch? i am reaching the limit of my electrics knowledge and very basic with a meter so its a steep learning curve. thanks Quote Link to comment Share on other sites More sharing options...
JeffR Posted July 24, 2010 Share Posted July 24, 2010 I had a similar problem a few years back, and it was the master switch (which was only a few months old too)replaced it and all was hunky dory. When I took the old(new) switch apart I could not find any obvious problems with it. Quote Link to comment Share on other sites More sharing options...

jbs Posted July 24, 2010 Share Posted July 24, 2010 If the dim/dip relay is in the same place as all other 90/110's then remove the clocks-by removing the 4 screws that hold it in situ then look into the area behind the clocks to the right hand side(you may need to use a torch to do this)and you'll see a pink/red relay attached to the bulkhead, the last time the symptom's you describe happened to me was when the relay was loose in the connector block all it took was for me to push it back in and all was right again HTH John Quote Link to comment Share on other sites More sharing options...
davie Posted July 29, 2010 Author Share Posted July 29, 2010 thanks all for help. Took to garage for testing and we borrowed the known good dim/dip relay from his landy and it worked so i have just fitted the new one and all is good. one dead dim/dip relay in the bin. davie Quote Link to comment Share on other sites More sharing options...
western Posted July 29, 2010 Share Posted July 29, 2010 there is a mod you can do, by fiting a jumper wire across 2 of the dim dip relay socket wires, then you can ditch dimdip altogether, it's not a legal requirement anymore, the light reg that concerns dimdip was resinded a few years ago.

Somewher I posted a sketch of which sockets you join in the relay holder. Quote Link to comment Share on other sites More sharing options...
