davie Posted December 17, 2014 Share Posted December 17, 2014 Hi, Garage is beaten by this one, and i dont have much clue on electrics. 2003 td5 defender. trailer electrics light stays on pretty much always. comes on as soon as you indicate either side and then doesnt go off until ignition off, tried new flasher relay - no differnence new indicator switch unit as a little bit of damage at plug for it found - no differnce unplug tow socket (genuine part) all pins lovely and clean - no difference if you just put ignition on fully, or start car and drive but dont indicate its fine. even sitting in drive with ignition fully on, soon as you touch indicator switch its on and stays on. so i am lost for ideas, and mot is up soon. ignition is a little worn, can take key out when running easily. wondering if anyone has seen this before? 1 Quote Link to comment Share on other sites More sharing options...
reb78 Posted December 17, 2014 Share Posted December 17, 2014 Try wiring up a new socket? The wired section is only a few pounds if its like mine and will insert into the current housing. Quote Link to comment Share on other sites More sharing options...
davie Posted December 17, 2014 Author Share Posted December 17, 2014 hi reb, do you mean trailer socket? if so it does this even when you disconnect it at the wiring harness plug in rear wheel arch so car cant see tow socket. Quote Link to comment Share on other sites More sharing options...
Crofter Posted December 18, 2014 Share Posted December 18, 2014 I had the same problem with my 1984 Land Rover 90 I tried disconnecting the trailer light plug to no avail, I only got rid of the problem when I fitted LED indicators, then I discovered the flasher unit was wet and corroded also I had earth problems so I would think that you may have an earth problem as you have already changed the flasher unit, the other thing that can affect the indicators is the hazard switch.

davie Posted December 18, 2014 Author Share Posted December 18, 2014 New thing spotted today. Once light is on and staying on if i flick the hazard switch it goes off imediatly and stays off. Quote Link to comment Share on other sites More sharing options...
Crofter Posted December 18, 2014 Share Posted December 18, 2014 Try a new hazard switch, as the indicators are connected with the hazard switch, when my sons 110 300tdi indicators stopped a new hazard switch cured this. Quote Link to comment Share on other sites More sharing options...
davie Posted December 23, 2014 Author Share Posted December 23, 2014 Well thats a borrowed hazard light switch been tried, no difference. so that should rule out relay, switch and stalk as all either new or new part tried. puzzled....

davie Posted December 23, 2014 Author Share Posted December 23, 2014 is the switch supposed to flash when hazards on? mine doesnt flash or light up nor did the replacement. Quote Link to comment Share on other sites More sharing options...
western Posted December 23, 2014 Share Posted December 23, 2014 Only if hazard switch has a bulb in it which it should have, trailer green should flash with hazard on as well Quote Link to comment Share on other sites More sharing options...
davie Posted December 23, 2014 Author Share Posted December 23, 2014 checked switch and theres a bulb, now no guarantee bulb is ok so not sure there. trailer green doesnt flash with hazards on. been round indicators today and all connectors are nice and clean, nothing green/nasty looking but gave all a hose of contact cleaner just in case.
