L19MUD Posted June 6, 2017 Share Posted June 6, 2017 2001 TD5 Discovery, started having problems with high beam not working and then when coming out of high beam to normal dipped lights the dipped would not come back on! Now in a position with the headlights turned to dipped where they are just on the dim setting No fuses are blown and this affects both headlights so I am guessing this is related to the Dim Dip relay? I am assuming that a TD5 Disco still has one despite it being an outdated thing. I have trawled through RAVE but cannot find a mention of it, or more importantly where it is! Does anyone have an idea where it is? Thanks Sam Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted June 6, 2017 Share Posted June 6, 2017 I would hazard a guess at a switch failure rather than dim-dip, classic symptoms. Quote Link to comment Share on other sites More sharing options...
IanS Posted June 6, 2017 Share Posted June 6, 2017 It doesn't have dim-dip. ISTR that went out in the 1980s....... Quote Link to comment Share on other sites More sharing options...
L19MUD Posted June 6, 2017 Author Share Posted June 6, 2017 Defenders had a Dim Dip relay throughout the TD5 era hence why I was thinking the Disco would be the same. The headlights do show as 'dim' with the sidelights on Quote Link to comment Share on other sites More sharing options...
L19MUD Posted June 6, 2017 Author Share Posted June 6, 2017 Might be worth ordering a switch as a first port of call, they can't be that expensive Quote Link to comment Share on other sites More sharing options...
Shackleton Posted June 6, 2017 Share Posted June 6, 2017 I've an intermittent problem on my Td5 Disco where one headlamp doesn't come on sometimes until I flash the full beam which seems to kick start it. I don't know the technicalities of this but it's as if the circuit has an obstruction and needs the higher voltage to force it's way through. Anyway, could you be experiencing an advanced version of the same thing? Quote Link to comment Share on other sites More sharing options...
L19MUD Posted June 6, 2017 Author Share Posted June 6, 2017 Have ordered a second hand switch off the bay of E for £10 and also ordered two ceramic H4 plugs with looms in case it is dodgy connectors causing the problem. Quote Link to comment Share on other sites More sharing options...
IanS Posted June 7, 2017 Share Posted June 7, 2017 The standard headlight connectors are definitely marginal. Quote Link to comment Share on other sites More sharing options...
L19MUD Posted June 20, 2017 Author Share Posted June 20, 2017 Just to update this it was indeed the switch Quote Link to comment Share on other sites More sharing options...
