18 Time to start driving slowly with 3 brakes.jpg
18 Brake "repairs" finished at sunset293 viewsWe just finished the repair at sunset and were driving slowly with 3 brakes. Oddly the D3 didn\'t behave any differently at 50 km/hr than it did normally. We had 4 instances of hitting the (3) skids for kangaroos before arriving in Wilcannia 3 hrs later. The brake light warning was making very distinctive noises and flashing randomly, though.

Breather_Cap_Front_Differential_LR019450.JPG
Breather Cap part # LR0194501510 viewsThis is the replacement breather cap as manufactured by the Gore Tex people, (Gore), for the engine compartment end of the front differential breather line.

You can with some difficulty, both blow and suck thru the breather filter material. The Gore Tex filter material has what are called hydrophobic and oleophobic properties. This means the filter material keeps oil in and water out, while at the same time, allowing air pressure to slowly equalize, (air permeable). Additionally, the transfer of dust, salt, and road debris is inhibited.

LP scoped 218 viewsBy connecting a Low Amps probe to the fuel pump's voltage supply wire, you can view the pump's current waveform on a digital storage oscilloscope (DSO). The scope pattern will reveal internal wear in the brushes and commutator that may not show up in a traditional pressure or volume test.

Observing the waveform will show if the pump's amp draw is normal for the application or is high or low, and if the pump is operating at normal speed or is running slow. Problems such as a bad spot on a commutator or a short or open in the armature also will be obvious in the waveform.

A "good" electric fuel pump waveform will generally seesaw back and forth with relative consistency and minimal variation between the highs and lows. A "bad" waveform will show large or irregular drops in the pattern, with large differences between the highs and lows.

Start of easy hill climb169 viewsTR mode Rock Crawl - although I did turn off Hill Descent as the other side was not too steep and she wanted to keep slowing dramatically which I didn't appreciate in convoy. (Where is my old Pajero that had the inclinometer?)

LR3 Battery Charger switch box and connector 0478.JPG
Battery Maintainer switch box and connector 716 viewsThe Hammond box contains a DPDT toggle switch with centre off. The Positive and Negative from each battery feeds to the switch. Depending on the setting of the toggle, (full left, full right,or centre off),the respective batteries connect into the pigtail that can stick out thru the grill when one wishes to connect the charger.

This allows one to charge each battery independently via a suitable battery maintainer. I use a CTEK unit that feeds a maximum of 3.3 amps at 14.4 or 14.7 VDC, depending upon setting. The wiring therefore allows for a slow recharge of either of the batteries separately if either one requires such.
LR3 Liftgate release mode with carpet removed, dust seal not cut 0596.JPG
Carpeted cover removed showing uncut dust seal and underside of carpeted cover. 1618 viewsNote that there are all sorts of electrical wires sticking to the underside of the dust shield - so be very careful when you cut thru the shield.

I used a box knife very slowly and was surprised at how many conductors there were running just under the shield membrane.
LR3_Stop_Lamp_Circuit_LRL183853501(LR3-Wiring).pdf
Stop Light Lamp Circuit pdf2461 viewsThis pdf shows the brake light circuit for the NAS LR3.

Note that power for the brake light bulbs can come either thru the brake light switch power feed /contacts plus also from the Hill Decent Control, (HDC), system relay located within the Central Junction Box, (CJB) - yes two separate sources of power for the brake light bulbs. This would tend to explain how a brake light circuit concern shows up as a hill decent fault message; also why lesser vehicles without hill decent braking mechanisms, (HDC), never display this sort problem when a brake light bulb or switch acts up. You never have a problem related to a system that does not exist.

Additional evidence of the relationship of the HDC and the tail light circuit is demonstrated by when the HDC actually acts to slow the 3 down, the brake lights automatically illuminate even if the slowing action was merely retarding the engine speed or shifting to a lower gear, (in other words, no foot on the brake pedal).

There is also a tie in to the Cruise Control and hence a failing brake light switch can affect cruise operation or just create false Cruise Control messages. To further complicate the issue, while there are no messages generated, operation of the radiator electro viscous fan can also be negatively affected by the fouled set of secondary contacts within the brake light switch. This is all because the NC contacts within the brake switch send misleading messages to the ECU.

While the ground wire design is similar to other vehicles, note the grounds for the brake light filament and the reverse light filament are common on each side. That means that if one has a non functioning brake light on one side, the reverse light may not also work or that some problem with the reverse lights could back feed into the brake lights. This situation while unusual, can result when grounds are corroded probably due to swimming in rivers and creeks or just routine driving in a marine environment.

some of the gates were very narrow429 viewsThe LR3's tight turning radius was a great help. You are only allowed one shunt (backup) per course section, so it is best to save it for when you really need it. I was very impressed with how slowly the LR3 can walk over the rocks, I had it set to rock crawl, and used either 1st or 2nd gear, depending on the terrain and size of rocks. mostly used 2nd, it give better throttle control.
