Right I have done a search but didn't find anything,

My 1990 Disco 200TDi has had a headlight problem since I bought it on first inspection it l thought it was the silly bastid who wired in the spots and their penchant for adding wires and piggyback connectors took out at least 20 foot of needless wiring and removed the unneeded lights/wiring, so that It was back to basics

This morning I have solved the sidelight problem (no fuse at all removed a wire linking it to the sidelight that works)

Now my problem is that I the dip and main beam is not working properly I used a testlight on the fuses and could get a dull reading from the fuses whilst the engine is running nothing whilst ignition is on no light from mainbeam at all, flashers work as normal. If left for 5 mins with the engine running the lights work as normal :confused::confused:

Now from my search I have found that the flasher bypasses the mainbeam/dip circuit but the fault IMO would point to a relay but if I have it right My Disco has no relay

So does this mean its the switch itself or am I missing something?

Hope this article doesnt fry brains couldnt think of how to explain it and tried to get as much detail as possible to help with diagnosis:eek:
 
not sure it helps yu, but all the headlight switching goes thru the indicator stalk which are well known for not being able to handle the current. Another place to look would be the fusible links along the o/s wing - there are about 4 or 5 big lumpy bits of wire that, if most are anything to go by, look a **** heap and full of corrosion. If yu look in the FAQ section there is a method to remove the headlights from the stalks, use 2 relays each side and only use the stalk as the switching method, without having all the currants squeeze thru.
