right hand lights out

My 98 disco is having a fit, the right hand lights and dash lights are not working. The signal and stop lights work fine.
I have checked all fuses and bulbs replaced the signal switch as well.
Any ideas were to go from here?

fuse ?

He has checked all fuses numty

Indicator stalk.

but how has he checked the fuse???
if it's only by looking at it, might still be boken
fuses wear out to you know

Because he said in his post i have cheked all the fuses come on guys
Fuse


A fuse does not wear out it blows and is very apparent yes he must pull it out and look but assuming thats what he has done to check his fuse then he has checked the fuse

Thanks for the vote of confidence, I used an ohm meter as well as visually checked them. As I dig into this deeper I am finding the flashers come on when I am on a bumpy road. Any ideas on that one?
I have also found what looks like a diode in the harness at the left rear light, is that what I have found or can anyone tell me what they are?

Flashers come on a bumpy road could be the inertia Sensor the car thinks it has had a accident so puts the flashers on and if the doors are locked it will unlock them try driving on a bumpy road with the doors locked they should unlock with the flashers coming on

I would say that you have a bad/intermittent earth somewhere.

First place I would check is on the inner wing just aft of the battery.

i'll remember that, so i must forget the last 25yrs experiance as an auto spark.

ok back to the fault.
as you have a meter, check voltage at the fuse both sides, then the switch input a (brown and green wire), then the switch output wires (red)
then just replace the fuse 33, then check the red/orange wires.
there is no diodes in the circuit just two headers(connections) which look like they are in the passenger fuse box? then check at each light unit.
if you have 12v at each check point then check the lamp negatives in the same way.

basically check through the circuit with a voltmeter starting at the battery pos to the load (which is the side lights RH) and back to the battery neg. where ever you loose the voltage shows which section the fault is in.

but it does seem likely it's the RH fuse 33, or the fuse box as the lights LH RH split up at this point.

As each headlamp has three lighting circuits so there's 3x fuses and all blowing simultaneously? come on, there must be a common point so that will be the earth connection.

head lights blowing fuses????? now i'm confused isn't this about the RH side lights inop????


the common point would be the fuse box or harness leaving the box to the lights, that would be a damaged harness more like, trapped or a screw through it, has any other work been done to the car just before the fault showed up?

Don't be confused any more, just read the opening post of this thread.. That will be the first post on page 1 to save you wondering.

say's nothing about fuses blowing??? or headlights, just the right hand lights?

You mention checking fuse "check voltage at the fuse both sides" why?? only fuse and not fuses ?? and doesn't "right hand lights" include head lamps?? perhaps also brake and indicator but then the OP states he has tested them.

you check the voltage at both sides of the fuse to confirm the fuse is 100% ok. a fuse can crack, so looks ok but doesn't pass current through it.
the test sequence is to trace which part of the system has failed, doing in order is a good way if your not sure about vehicle electrical systems.

Think you Sparky Steve, I give it a go and let you know if the thing will cooperate.
Let you know soon.

would'nt this one cut the fuel off too?... let's just hope it's not BCU or IDM related. IMO the lamps and the flashing thing are not related...cos if they are it's a fusebox internal fault issue.
