mmgemini Posted June 6, 2008 Share Posted June 6, 2008 Where is the earth to the body ?? I have the battery box out. The earth goes to the chassis and then to the gearbox. How do the lights get earthed ? mike Quote Link to comment Share on other sites More sharing options...
Lars L Posted June 6, 2008 Share Posted June 6, 2008 At least the bulkhead is firmly attached to the chassis without any rubber in between. Quote Link to comment Share on other sites More sharing options...
Les Henson Posted June 6, 2008 Share Posted June 6, 2008 The earth for the lights is within the wiring loom Mike. Earth strap from the starter (or near to it), is connected to the chassis, and therefore onto the bodywork. There are many earth points off the body for the various earth wires - for the rear lights there's a nearby earth point with a short jump wire for the various bulbs. I would say that it would be the same for the front lights too - although I don't know the location of it. Les. Quote Link to comment Share on other sites More sharing options...
mmgemini Posted June 6, 2008 Author Share Posted June 6, 2008 Les. There is no wire from the battery to the body I'm assuming that the lights, on the body, get their earth from the various rusty connections where the body is attatched to the chassis. Would it be prudent to put an earth from the battery straight to the body as well as the other points. mike Quote Link to comment Share on other sites More sharing options...
Les Henson Posted June 6, 2008 Share Posted June 6, 2008 The earth gets to the body via the chassis Mike. If you have the earth wire from near the starter to the chassis - then that's where it happens. Les. Quote Link to comment Share on other sites More sharing options...
Guest diesel_jim Posted June 6, 2008 Share Posted June 6, 2008 The lights all have their "own" earths (the black cables) that route back and pretty much get connected together somewhere down the line. Also, on the rear lights, there is a bolt-terminal on the bodywork itself that the black's connect to with a ring terminal. Quote Link to comment Share on other sites More sharing options...
mmgemini Posted June 6, 2008 Author Share Posted June 6, 2008 Yes Jim I know that. However the body isn't connected to the battery. Well not on mine. So as you say"somewhere down the linew" Where is that line ?? The earths from the battery go to the chassis. The body sits on the chassis, so I'm presuming the lights, whichas you all say and I already know are earthed to the body, so the lights must earth at the places where the body sits on the chassis. Faith hope and charity I think. For what it costs I think I'll add a body earth. mike Quote Link to comment Share on other sites More sharing options...
western Posted June 6, 2008 Share Posted June 6, 2008 the front lights are earthed by a ring terminal [part of front lights loom] to the vertical inner side panel visible from the headlight bowl hole [obviously with the light removed]. rear lights are earthed to the left & right wheel arch box behind the small light protector panels in the rear corners, these are connected within the looms to the bulkhead earth adajcent to the fuel filter, the body is earther to the chassis via all it's attachment bolts, the only earth leads on my 110 are from battery -ve to gearbox/transferbox joint & from left chassis part of engine mount to the alternator/power steering pump bracket/engine block. I haven't found any other earth's between the body/chassis other than ones I've added for various additions. Quote Link to comment Share on other sites More sharing options...
mmgemini Posted June 6, 2008 Author Share Posted June 6, 2008 Yes Ralph... I'll be adding one I think. mike Quote Link to comment Share on other sites More sharing options...
Aggieturbo Posted June 6, 2008 Share Posted June 6, 2008 Of course all of the above assumes that the wiring is still as per the Land Rover build spec.! My 1988 110 has had some 'work' done on the electrics, and it now takes me the best part of a morning to trace any electrical fault! I might as well throw away the wiring diagram.

I might as well throw away the wiring diagram. Apart from the headlights and the stuff that comes off the aux battery...Yes it is original. You're lucky. There isn't a wiring diagram for a 1995 build 110 Defender. You have to use two different ones and work things out for yorself. mike Quote Link to comment Share on other sites More sharing options...
Mo Murphy Posted June 7, 2008 Share Posted June 7, 2008 Mind if I join you, Mike ? A short earth from seat box to negative terminal ought to do the trick Mo Quote Link to comment Share on other sites More sharing options...
mmgemini Posted June 7, 2008 Author Share Posted June 7, 2008 Mind if I join you, Mike ? A short earth from seat box to negative terminal ought to do the trick Mo Not at all Mo. I've suddenly realised that I'll have at least three relays in there. Makes sense to add a 6mm stud for the earths. Ive started the new battery box. For those interested it's here... http://www.landroveraddict.com/smf/index.php?topic=369337.0 Helpful comments welcome. mike Quote Link to comment Share on other sites More sharing options...
Guest diesel_jim Posted June 7, 2008 Share Posted June 7, 2008 Mike, i was looking at the seatbox i've bought for my 110 (It's a Td5 box) and it's got a couple of studs welded into the bottom of it, with little screw on "nuts", obviously there to attach earth rings to. sounds like a good idea IMO. also, i reckon putting an earth strap to the bulkhead (although previous rovers of mine have had these) onto the chassis should help things too.

Well I'm pleased so far.Two batteries are in for fitting. Quite a bit more room. I'll be taking it to bits agian for more measurements. mike Quote Link to comment Share on other sites More sharing options...
mmgemini Posted June 7, 2008 Author Share Posted June 7, 2008 What size studs Jim 6mm or 8mm ? mike Quote Link to comment Share on other sites More sharing options...
Guest diesel_jim Posted June 7, 2008 Share Posted June 7, 2008 What size studs Jim6mm or 8mm ? mike 6mm. i've not got the box here at the moment otherwise i'd measure their location (i took all my panels into the stray shop yesterday), but it's on a Td5 seatbox under the RH seat (just realised it's the ECU side, but obviously it must "earth" verious crucial cables for the engine management that need it, so it wouldn't hurt to do it for the rest of the vehicle either) the nut thing is a plastic nut, whether this is done for electrical insulation, not sure. (ie, something falling on it)... Quote Link to comment Share on other sites More sharing options...
mmgemini Posted June 7, 2008 Author Share Posted June 7, 2008 The 2000 model year 300Tdi has a huge fuse box in there. Well the South African ones do. mike Quote Link to comment Share on other sites More sharing options...
