Title: Electrical nightmares
Post by: dap1977 on June 08, 2013, 12:43:06 PM
Hello all,

I wonder if any one can shed some light. None of my electrics in the cabin seem to work.

When I put the the key in and turn it to position 2 (ready to start) I dont get any lights come up on the dash at all. I would of expected somting to come up (Battery light ect, abs light ect)

Ive searched through the posts and followed the obvious pointers. These being replacing the dimmer switch. This now seems to work, the gauge illumination goes up and down.

Ive seem people mention the TNS relay, but I have side lights and reverse lights so I assume this is ok.

Does anyone have any advise, Im starting to think im in over my head with the Rex!

as we said on fduk mate you need to go through every fuse in the engine bay and drivers footwell to rule them out if you have done this then you will be onto testing the live feed to the ignition switch etc but if you want advice you need to confirm exactley what you have done and ruled out otherwise you will just get the same response all the time

I would check the relays that are on the slam panel were the bonnet shuts first, from memory some are interchangeable

Next up get an electrical test, or even a 12v bulb with two bits of wire and find out where you have power and where you don\'t on the loom

hope this helps

Thanks guys,
 
I have been through the fuses in the cabin and in the engine bay and all were ok.
 
I havent started pulling relays as yet as the systems they seem to identify work I think. I did notice that I havent got one in the position marked \'Retra\'. I thought this was for the pop up lights, but these work fine without it??
 
I checked exactly what works and what doesnt today.
 
All external lights work, interior lights work, gauge illumination works now I have changed dimmer switch, electric windows work, central locking works.
 
Dash warning lights dont work, climate control unit does not work(interestingly hazzard warning light switch does work just the rest of the unit is dead)
 
Good tip about the bulb and 2 wires, Ive also seen somthing about dry joints on the fuse box. Is this common do you know?
