introduction but needs help

Good morning,
My name is Harry I'm 22 and trying to help my mum out with her Landy 1995 Disco 1 M reg, she is currently in Tring near Aylesbury.

Issue is the driver side indicator isn't working so I tried replacing the bulb fitting and new bulb. still nothing so then replaced the Little metal fittings that fit to the bulb housing. still nothing so I decided to cut back the wire to some fresh wire and reattach it to the bulb fitting. upon doing this I found one of the wires with whiteish dust and the wire was really thin and just crumbles leaving maybe 3/6 hair strands of wire. I tried to gather as much as I could and refit still nothing all other lights work.

Situation - its awaiting its MOT and its her ONLY CAR so I need some help. if anyone is near Tring or Aylesbury that's willing to help me would be great!!!

Thank-you

Harry

Nice finger nails Harry.
Maybe it would be wise to make sure there is a live on the wire going to the bulb.
Then make sure you have an earth.
I have no idea what a Disco bulb holder looks like, post up a picture showing the holder and wire colours.
Also people can help better if you say which indicator it is

Hahah not mine, sorry to disappoint I'll have look about the live and earth.
Its the Drivers side Indicator. in the picture attached you see fitting that I'm attaching the wires too.

I know there is power going to the wires as I tested it with an Led bulb it lit up but very very dull and flickering.

You have a known working bulb and holder on the other side, swap them round to confirm both bulb holders work.
Presumably there is a little multi plug that pushes into the bulb holder
If both bulb holders work then try a temporary earth wire from holder to a good clean earth.

Ok thank you I'll give that a try. appreciate the help.

Fixed it yet?
