I've had most of the common mechanical failures, altenator, water leaks, wiper failure, door/hinge problems, roof rust, floor rust, loads of electrical problems. Remember, I'm not a dealer or a mechanic, just an owner like most of you.
Experience
Experience Owner of a Discovery. I've had many mishaps with our Disco but I still like this vehicle. Talk to a fellow LR owner instead of a dealership rep. I'm not in this for the money. I'm just an owner who wants to help others.
Question i have a discovery 2 with a rear eye level brake lamp that not working but it's not the bulb that broken. i don't know which fuse number it coincides with,what else might be wrong with it apart from that?
Answer Hi Andy,
how's the weather over there? Well, I hope.
Here's what LR has to say about the high mounted brake light
Brake/Reverse Lamp Supply
Circuit supply
A feed from the battery positive terminal is connected by an R wire to the engine compartment fusebox where it passes through fusible link 8.
Ignition switch supply
In the engine compartment fusebox, a feed from fusible link 8 is connected to the passenger compartment fusebox by an NW wire. The feed passes through the fusebox and is connected to the ignition switch by an N wire.
When the ignition is switched on to position II, a feed from the ignition switch is connected to the passenger compartment fusebox by a Y wire and passes through fuse 25.
Brake Lamp Operation
A feed from fuse 25 in the passenger compartment fusebox is connected by a GO wire to the brake pedal switch. When the brake pedal switch is operated, the switch contact closes and allows current to flow on a GP wire, from the switch, through header joints C0287 LHD/C0290 RHD and C0295.
From header C0295 a connection on a GP wire allows current flow to the LH brake lamp. Another connection from header C0295 on a GP wire, goes through header C0723 and allows current flow to the RH tail lamp.
A second connection from header C0723 on a GP wire, allows current flow to the high mounted brake lamp.
A third connection from earth header C0723 is connected to the trailer pick-up (if fitted) on a GP wire. The trailer pick-up is earthed on a B wire to earth point C0808.
Ground:
The LH brake lamp is earthed on a B wire to an earth header C0707. The RH brake lamp is earthed on a B wire to an earth header C0706. The high mounted brake lamp is earthed on a B wire to earth header C0706.
When the contacts of the brake pedal switch are open the connection from fuse 25 in the passenger compartment fuse box supplies:
Automatic V8 vehicles
A feed on a PG wire to the cruise control ECU.
Manual V8 vehicles
A feed on a OG wire to the clutch pedal switch.
Td5 vehicles
A feed on an OG wire to the ECM for cruise control operation.
