Electrical Woes

Hello all!

I wonder if anyone has any bright ideas for my Freelander...

Several electrical components - windows, all dash display/lights, indicators, air con, perhaps others have died leaving the car driving absolutely fine with wipers etc still working.

The ?E5 earth that runs down the offside A panel doesn't seem to be good (doesn't beep on continuity test to body of car) however I can't seem to find where it runs to/from without dismantling the entire car!

Could this be the problem? If so, can anyone tell me where the terminals begin and end, what to look for, or any pretty simple ideas?

I guess it will go to the garage next week but I could REALLY do with opening some windows or AC on a 31 degree weekend!!!

Thanks in advance,

Kat

You should say what type of Freelander it is - there are a variety of very different vehicles out there.

Really good point! Sorry, its a Freelander 1, 2002 TD4.

Do you get continuity/beep from the point where youre testing to anywhere else. Just to be sure it is supposed to be earthed there, and do you get a good contact to bare metal.
Is it deffo an earth cable youre testing?
Have you got voltage between known earth(battery if poss) and the fuses for the affected items. On the fuse, without removing there's a small bit of metal that will be +12v.
I'd check for voltage first at the fuses and take it from there.

Hi Kat, greetings from North East Jocklandshire where we enjoyed/endured the giddy heights of 25°C today - us Scots aren't acclimatised to these kinds of temps - anyways, starters for ten would be:

• fix that earth point, crimp on an eyelet, scrub up a bit of metal work and self tapper the eyelet to the newly exposed metal - voila, one homebrew replacement earth point
• remove the battery +ve terminal and open the engine bay fuse boxes and remove and clean all the fuse-able links, eyelet terminals etc with some scotchbrite - shiny metal conducts better than oxidised / tarnished metal
• quickly check all the fuses from engine bay fuse boxes and cabin fuse boxes
  • While testing the fuses in the cabin fuse boxes the systems that don't work, put the two probes of your meter across the spade terminals in the box that the blades from the fuse go into and check for voltage - check the terminals for voltage against each other, and check the terminals for voltage against the chassis/body (earth point)
  • you're doing this to make sure you have electrical supply to the affected systems

Check and see if things start working again after each of those steps, if not move on to the next one, if things work after one of those steps, sink a bottle of white wine to toast my genius and your success, and if they don't work after all of them, what do you expect, I'm only a Jocktard
