I had a 13pin towing electrics fitted to my 08 SX auto last September (2012) by a local towbar fitting firm. But have had problems with it every time I take my caravan away, everything works ok plus the trailer warning light on the dash when I check the lights before we start our journey, but about a hour or so into that journey the indicators and side lights fail. The trailer warning light doesn't light when the indicators and side lights stop working all other lights work ok and the Alco ATC system on the caravan is still working ok. The first time it happened I called the RAC out and they found the earth was not tightened. It worked ok untill our return journey when the same thing happened all I did was take the earth off and put it back on again and it worked again. I have taken it back to the company a few times now and they have moved the earth, reprogrammed the software but its still happening. Any ideas what I could do next. It's a witter towbar and electrics.

i had a 13pin for my trailer (not twin electrics at the moment) and at the time the company that fitted it said they had to use the proper Land Rover unit as others wouldn't possibly work properly.

Going on that basis possibly witter electrics arn't the right ones for a freelander.

You could try running an earth bonding strap from the earth lead you have to another, very obvious, earth point on the vehicle. Just in case the *exsiting* earth point is not very good.

Hi yes they have moved the earth point to the one used for the rear lights on the car but still keeps failing. The next thing they are going to do is replace the wiring loom, they have also replaced a module on the trailer loom but that's made no difference!! To reset it when it fails now I have to unplug the module on the loom and plug it back in. The only time I can test it is when I tow my caravan so that woun't be for a few weeks yet. I have plugged a trailer board in and run around with it on the back seat but it didn't fail then.

There is a possibility that either your Alko ATC is incompatible with the Freelander's CAN Bus or/and/maybe you have LED rear lighting on your caravan that is also incompatible and a known problem.

Hi Guys
The Alko ATC seems to be working ok and the only LED lights on the caravan are the yellow side marker lights. I've spoken to the towbar company and they are going to change the wiring loom next week, They said there is a modification to the new loom and they have to run cables from the front of the car. to be honest when the RAC discovered the earth connection hadn't even been fitted to the body work. I've had no confidence in the way they have fitted it in the first place and can not understand why they have to run new cables when they should of done that in the first place. I'll have to wait a few weeks to see if it works. Thank you all for your responses so far, keep them coming.

landrover electric kit is the only way to go with a Landrover ! I wouldn't put any other electrical module anywhere near a Landy can system . Trouble with a capital T
