Hey up peeps,
I've just finished banging my head on the Landy with this problem without success and so I thought I'd continue banging it on the forums to see if I could fair any better.
I've got a 300tdi Defender 90 which until this winter has been dream. But as we all know, we wake up from dreams and reality takes a swipe! She's developed an electrical fault. When I activate main beam, the fuse for NS blows. Initially I pulled over, replaced the fuse and all worked well again for 2 minutes, then it blew again. Replaced it, same issue. I have 100W spots separately switched and fused, so thought it might be the problem. Set out this morning to solve it as follows:
Switched off Aux spots - fuse still goes.
Disconnected Aux relay - fuse still goes.
Checked the main beam feed to the Aux relay - everything OK. - I've ruled out anything to do with the Aux spots.
Since checking this lot out, the fuse no longer waits a couple of minutes, it goes immediately, whether the beam stalk is pushed forward (on full time) or pulled back (flash).
I've disconnected the NS headlamp - fuse still goes.
Cleaned and checked connections to the headlamp - fuse still goes.
Checked connections to the column switch - everything seems in order - fuse still goes.
So, now I need a big bag of fuses and some help! Has anyone here experienced the same thing? My next stop is to replace the column switch and see what happens, I also read that there's an earth under the wing somewhere that might be dodgy, what do you think?
It may be co-incidence but I replaced the battery a few weeks ago when we had the big freeze and since then, the water temp gauge tells me she's running a fair bit hotter (even in -10 temperatures) and this light issue has sprung up. Does it fit or am I just looking for excuses here?
Thanks for your help people
