Fuse boxes?
Choices abound. Anything from an inline fuse to 4/6/8/12 fuse boxes. Prices from a few £ to up to about £50 Which one to go for? Well the ones we use in our vehicles are 12 fuse box with a common negative bus bar. We take negative cable from the equipment back to the fuse box and hence battery rather then using the chassis as earth return path. Hopefully helps avoid those potential earthing problems If you have a twin battery set up don't put it in the main battery box (unlike Devon ) If you need to change fuses and have it in main battery box with twin batteries you may just have to take a battery out to replace a fuse! OK small hands, small batteries you might get away with it. In black puma it is located in drivers box. In red overland vehicle it is in the battery box Yes I need to sort out that battery box one day HTH Brendan Brendan Admin note: this post has had its images recovered from a money grabbing photo hosting site and reinstated |

Right guys what is the high beam warning lamp wire for 86 ?.........and do's the 12v dash illumination wire just connect to a live in the dash ?

Looking at the wiring diagram for the TD5, windows, heated seats, fuel pump etc are all controled in the +ve circuit. Land Rover use earth to switch relays, as like you say this cuts down on cable runs, but in most high current circuits +ve is allways switched and the device bonded locally to earth, again cutting down on cables run. Best practice is to switch +ve load on relay applications. Last edited by Paul_1978 on 19th Jan 2011 7:02pm. Edited 2 times in total |

The high beam wire is to supply +12v to the relay, so spots can not come on without high beam being selected on the stalk. The colour of that wire is as land rover loom, can be found at the rear of the dash. Easy way to pick up illumination is to piggy back off the fag lighter lamp, just need +. |

I actually beg to differ in this application. Spotlights have their own +ve anyway without any input from the fact the switch is driving the earth circuit - the +ve is a feed from the battery via the relay to the lights all the earth feed is doing is the exact same thing as the +ve swtich feed - which is making the relay able to switch the current - both earth and feed only need an amp at most. I also wouldnt wire it like that (although i accept its a wiring diagram issue probably) if i was wiring to +ve Mike |

I kept them independent - the spots are higher wattage than the road allows in the UK anyway.
Plus its nice to have them as a back up should you need or on without mainbeam as well - when mine are on there is no need for mainbeam. For those reasons it doesnt trigger from main beam Mike |

I think we are talking about different sides of the relay, in the diagram i posted, the relay is switched on the negative side with the switch and + side with the high beam, this is to control the relay. On the power side of the relay, + is switched, which is normal practice, to supply power to the load. If switching -, this means the + wire is live, and can short to earth causing fire if the fuse dosent blow. Also causes problems during maintenance, touching parts against the car. |
