Thread: Fuses ,

I would like to add to my question . Did you know that the Puma has a permanent live in the Grey multi socket at the rear up behind the flap . Drivers side . It's live without any any ignition on . This could be very handy . This is the live fuse I can't find ???.. Jim..

From memory it's in the panel under the steering wheel.
There's also another series of fuses under the drivers seat but don't think it's one of those.

I assuming from your second post that you have a Puma engined Defender? If so, the factory manual has a good description of the fuses.

I think the permanent live wire depends on which model Defender you have. I went looking for it when I was doing my wiring as I needed a feed and it wasn't there. From memory it was stopped when they bought in the 2.2 motor.

Anyone else with more information feel free to correct me if I'm wrong.

What's the specs of your vehicle? It's a pretty important thing to know if you need more specific help than "the fuse is in the fuse box".

From my understanding, if you think you've blown a fuse, grab your multimeter (an essential tool IMO- can be picked up for <$20), and check continuity across every fuse you come across on the vhicle. Usual locations are under the driver's seat, below the steering column, sometimes at the battery itself. If there's a fuse there, and it's blown, then check that it's got power going to it (on the beattery side) and replace. See if that restores power to your wiring at the back of the vehicle. The fuse diagram is also very helpful- but I'm assuming you've tried that as it's the most common place to start.

If you are unsure what wiring goes to a known location on the vehicle, best way is to check continuity.
Disconnect the battery entirely from the vehicle, and run a long lead from your location at the rear of the vehicle back to the fuse block. Probe connections at the fuses until you find continuity. A multimeter with a beeper is a good help for this job. You'll get continuity on the earths, but this can be cross referenced by touching the probe to the vehicle body to double check. When you find your positive wiring, you'll know where it goes in the fuse block. You can also trace the path of the loom to get an idea where it goes. On the defender, it's basic- it should go along the passenger's side chassi rail back thru the wheel arch, loop over the chassis to the centre of the vehicle, and go into the fuse area under drivers seat.

It would be unusual given automotive wiring for a fuse to be anywhere other than at the battery, or in the designated fuse blocks. If I were a gambling man, I'd wager that if the power wiring is in fact installed in your vehicle from the factory, than it would be fused at one of the fusible links on the main block under driver's seat (the square plug in doo-dads).

Hi , Yes It's a Puma , As I found out there is a permanent live wire , in the harness , It is coloured mauve . and was constant live . I brought a britpat harness , It is so much better than the Land Rover one . The britpart harness also fits the Disco 2 and has a branch that would go up to the higher tail lights reverse plus the permanent live , It changes colour to red at the connector . I went to the hand book , then to both fuse boards , under seat , and foot well , but I can't find what fuse It is ? Jim

I have a new 2.2 and It is in the socket at the back , It is Mauve , and permanent live , without any ignition and could be very handy !!.. Jim

Hi Mich , I check all wires at installation of new harness , wondering what the extra two were , One I found to be live , constant . the other only came on when in reverse , ignition on . Happy with that I ran them into the back though a hole , but I took the plastic snap connector off and taped them up . for insulation . This is where I must have blown the fuse , I must admit , I didn't look at the battery , to see if It comes from there . I will find It , but It may take me a bit of time , using my multimeter , and test light . I just thought It would be nice to have a live up the back , saves me running one !!.. Jim

I'll go have a look next weekend because I couldn't find it. But I didn't want a permanent live for the job I was doing so I ran an ignition wire from the dash.
