LR3 miscellaneous
|
|
This album contains both data and fun stuff.
The data is generally boring pdf wiring diagrams that do not seem to belong elsewhere as well as various system explanations. There are also a number of files related to the alternator and regulator plus some files related to various 18" and 19" D3/LR3 rated factory wheels.
The fun stuff, is well - look at it.
I note that the Marilyn file within this album is over a thousand views - a very discerning mindset I suppose on the part of the Disco 3 forum participants.
There are other albums here with a number of files exceeding 2,000 views, a few exceeding 3,000 and the odd file having 4,000 views. The majority of the files however show perhaps 400 to 500 views.

Liftgate release mod
|
|
I installed this mechanical release in anticipation of the power operated upper hatch door release quitting for whatever reason. In the cases of the early production models, there is an L shaped plastic part that simply breaks. It has since been upgraded to metal and fails less often now. This mod provides a mechanical release as LR does not.

LR3 Air Suspension fuse 35P ECU Manual Shut Off Switch
|
|
At first I did not quite understand how the system worked and thought that removing Fuse 35P was the key to freezing the suspension computer. I later determined that removing F26E in the engine compartment would kill the computer 24/7/365 and keep it dead. Removing F35P only put the computers to sleep while the engine is running; later when shut down, the zombies wake up and drop the 3 while parked. Removing F26E is pretty much equivalent to putting a stake to the heart and kills the suspension computer "good".

NAS Trailer Socket Pin ID and Wire Colours
|
|
Album provides wiring hookup diagrams and colour codes for NAS trailer sockets; additionally an adapter box design that can be self built to eliminate pulsing of LED trailer lights.
The adapter also facilitates the required signalling to various onboard computer circuits that a trailer is connected and hence results in the automatic disabling of such features as the backup sensors and auto height lowering at speed.
Also depicted are various NAS hitches available as well as providing part numbers for an electric braking controller device that can be connected to the existing factory Ford wiring connector.

This details how to install a Schrader valve in the front end of the air tank of early 3's to facilitate "air in" in the event of compressor failure.
Later build 3's do not have the blanked off threaded bung that provides the required entry point.

This file shows the replacement of the LR3 rear upper hatch switch with a similar switch, but with a Range Rover Sport part number, hence a JAE connector has to be added to the LR3 wiring to accommodate the plug on the end of the RRS Switch.

Power Window and Door Lock Circuits
|
|
A collection of pdf's re the power window wiring and also the door lock wiring.
There is a 17 page pdf that attempts to explain how the door locking system is supposed to function. While the explanation is actually quite detailed and fairly easy to understand, overall, the locking system is not simple.

Breather Cap Front Differential installation
|
|
This album shows the installation of the Front Differential breather cap per Technical Service Bulletin LTB00245. What surprised me was that the piece I cut off, I could neither blow nor suck thru it; the new replacement breather cap, I could.
I tend to wonder what Land Rover knows that is not really mentioned in the instructions that generated the TSB.

Thermostat Housing LR005631261 viewsWhen the time comes to install a new thermostat, consider installing the whole housing instead.
Advantages are the thermostat is correctly installed, (not as simple as it should be); you get all new plastic and that is important, plus a new coolant temperature sensor and also a new heater coolant bypass valve, the secret part no one realizes is also within.
The cost of the whole assembly is not much more than the cost of a factory thermostat and the effort to replace all is not as difficult as it might seem.Feb 03, 2018

Cooling System - Description and Operation 4.0L and 4.4L petrol engines 5 pages542 viewsThis is a 5 page pdf that provides some insight into how the coolant flows thru all the hoses. Of interest is the paragraph,(page 3/5), that attempts to explain how and why the thermostat is designed to open at different engine operating temperatures - in brief, the reason for the spaghetti tangle of small hoses on the top of the engine.
There is also reference to an engine oil cooler that I gather cools something I think related to a supercharger, if fitted.Jan 28, 2018

Alternator female plug looking down into top204 viewsThis shows the plug connected to the alternator wiring harness looking down into the top of the plug.
The cavity marked 1 is the AS or BATT SENSE and the wire colour most likely has Brown/Green on it.
The cavity marked 2 is the RC or ALT CON and the wire colour most likely has Red/White on it.
The cavity marked 3 is the L1 or ALT MON and the wire colour likely has Green/White on it.
I say "most likely" as the wire colours are not always the same on all vehicles.
Also the terminal 1 conductor destination is more likely C0570-175 rather than per the jpg.
The #3 pin is located closest to the big B+ terminal.Dec 13, 2017
