13 pin towing socket fusing.
Hi Guys,
Got a problem with my towing electrics. The feed for the fridge, pin 13 was dead as is the permanent 12v feed, pin 9. I traced the pin 13 fault to a u/s relay, when I bridged it I got power to pin 13 sorted! So my problem is pin 9. According to the instruction sheet which came with the vehicle it is a 20A supply but there is no separate fuse as there is with the pin 13 relay so I assume that it must tap into the vehicle harness and rely on a vehicle fuse, question is which one, there is no mention of towing electrics fusing in the hand book, can anyone help. Btw the wiring kit which was fitted is Part No 29190504RC and it is Defender specific.
Thanks

That's an aftermarket kit, so it wouldn't be covered by any details in the vehicle handbook.

I can't find the instructions for the 29190504RC kit online, can you post them?

Pin 13 is the ground for pin 9, not ignition 12V! You should be looking at pin 10.  1988 90 Td5 NAS soft top

Found PDF https://www.pfjones.co.uk/pfjoneswiringkit..._01-99.pdf

It appears to have a voltage sensing relay in it to control the pin 10 (ignition). Is that what you've got fitted still?

It connects straight to the battery, and then in the usual place under the wheelarch.

If it picks up the permanent supply from the wheelarch connector, then this is supplied from Fuse 2 (20A)  1988 90 Td5 NAS soft top

Yes, you’re right Martin, pin 10!, just a mistake as I typed! I did test the correct ones Thumbs Up The fridge feed seems ok, or will be when I replace the relay, I’ve got a Durite one I may substitute. Just a bit surprised that there is no mention of towing electrics fusing in the HB as LR supplied and fitted towing electrics and they mention fusing for other original “accessories” whether you have them fitted or not.

Here are photos of the instructions, just the pictograms type I’m afraid!

Hi Martin,

We must have crossed in our posts!

Yes, that’s what I’ve got, it’s the pin 9, permanent live, which is dead, I’ll check fuse 2 now and report back.

Hi Martin,

Checked fuse 2, ok, checked the supply to the fuse, ok, so it looks like I’ll have to start looking for a bad connection somewhere, probably where the tow electrics harness is connected to the vehicle harness at the rear.

Many thanks for your help locating the right fuse, inside the fuse box cover there is a picture of a trailer, why not in the HB Question

I had loads of faults that were all down to that connector which for is placed in the most awkward and dirty place on the vehicle. It got so bad I made up my own fused leads back to the lights and battery. Don't make old people mad.

No idea how this happened! It’s a wonder it didn’t blow the fuse! 2010 Defender 110 Station Wagon, Santorini Black.

That's clean, mine at 4 year old had about an inch build up of road filth and only used on a road. Don't make old people mad.

Yes, not too bad, but I had to dig out quite a lot of mud to get to it!

I’ve sorted the problem now, cut back and spliced in a new piece of cable, soldered, heatshrinked and I put that section in some split convoluted tubing. Before I put the plug/socket together I drenched them in electrical contact cleaner and then a liberal spraying with silicone grease after reassembly so 🤞!

Still can’t figure out what has happened, my only thought is that I had the tank dropped about a year ago, maybe it was damaged then?

Also replaced the faulty relay with a Durite VSR I happened to have, so all is working in time for me picking up my Eriba next week 😀 2010 Defender 110 Station Wagon, Santorini Black.

Well worth fitting the Gwyn Lewis mud flap kit. Wink
