Hi all,

My 2000 Td5 Defender keeps blowing the No 11 Fuse. This is a 10A fuse
and all it does is feed the LH Side light, LH Rear light and number
plate light.

The problem is not a straight short because Ive replaced it again this
morning and all lights work fine immediatly after changing the fuse.

After a 2 mile journey to work they are still working, but this is the
3rd fuse Ive had to change in 3 weeks???

The side light and rear light are the correct wattage (havent checked
the number plate light though).

Come to think of it could the rain be getting in anywhere?

Any ideas or suggestions please?

Thanks
Jon

Have you give the light fittings a good clean out? Could be some crud in
there causing a short sufficent to blow the fuse.

Is it fitted with towing electrics?

If so check the cable to the Trailer socket has not chaffed on the
chassis / tow bracket

Marc,

No Tow-bar & electrics fitted. Where would I find the loom that those
"missing" electrics would plug into the check at that end? Rear cross
member somewhere?

Thanks
Jon

Lee,
All light clusters (rear of fitting and wires & lenses at least) are
clean.

Thanks

Behind the o/s/r wheel is a thick rubber flap that hides the back of the
lamp units. Tucked up in there will be a large plug that the towing
electircs plug into.

Check the rear number plate light otherwise known as "Rear Loom Short
Circuiting Device"
Land Rover have been using the same unit for years and they are
guaranteed to short to earth after a while, internally they are a crap
design and if moisture gets in, a short to earth is certain. Same unit
on my 101 and it fried the 6 way light switch, be thankful you have
several fuses and not just one 35A to isolate the entire lighting
circuit.

Stick a 35A circuit breaker in there, then you can clout it if
darkness strikes!

I had frustrating fuse blowing fun & games with my RR P38. It would be
OK for weeks or even months then suddenly start intermittently popping a
fuse that supplies the climate control, ABS ECU, brake lights and a few
other bits. I'd replace the fuse and it would be Ok again for a while. A
pig to isolate what was causing it. It was worse in the summer so I
thought it was something to do with the climate control, nope, wrong. I
eventually narrowed it to the brake light circuit and it was a wire to
the centre brakelight that had been squished between internal trim panel
and the metal in the upper tailgate. I guess it was worse in summer
because of expansion in the sunshine squashing the wire a bit more.
