    Disco 2 No Brakes of almost no brakes.

    Removing the Alternator is fairly easy when you have cleared away all the structure around it, fan cover, fan and the cooling system bolted above the fan pulley, battery box etc. The bolt in the bottom of the Alternator is difficult to remove that is unless you remove the idler pulley. The big...

    Disco 2 No Brakes of almost no brakes.

    That does not explain why I was able to start my vehicle, after sitting for six weeks, and drive it onto a transporter. When it returned from its chassis replacement, ten weeks later, it would not hold a charge. New battery £149... The Discovery 2 was designed in the late nighties and may or may...

    Disco 2 No Brakes of almost no brakes.

    Yes! The system works well when the Alternator output is between 13.6V and 14.2V. Any higher and there is the probability of 'cooking' the battery i.e. boiling off the electrolyte and therefore reducing the batteries capacity to hold a charge. Also a battery voltage of 12.8V is considered normal...

    Disco 2 No Brakes of almost no brakes.

    I changed the Alternator because its output was 14.63V and my battery that held a charge for over six weeks prior to the chassis change was now not holding a charge. The air pump / sucker(!) was not at issue indeed it was covered in oil, possibly affecting the alternator. Therefore I changed the...

    Disco 2 No Brakes of almost no brakes.

    All the above replies seem to relate to the air pump on the Alternator. The Alternator was replaced less than 200 miles ago! However with the engine running I pulled the servo pipe off the servo and held my finger over the disconnected pipe; the other end was still firmly attached to the air...

    Disco 2 No Brakes of almost no brakes.

    Could be the ABS! However I would expect the SLABS ECU to light up a warning light or two. But thanks for opening that line of thinking. When it first happened the pedal was soft, it was softer than usual after the new chassis, so I double pumped it and got a solid or almost solid pedal. (I...

    Disco 2 No Brakes of almost no brakes.

    Returning cross country a 60 mile trip going through a built up area my brakes suddenly had an almost solid peddle and much diminished braking efficiency; not as effective as my old 109" drum braked vehicle! No warning lights and a quick check to the brake fluid levels indicated fluid in the...

    Second error. Diagnostic socket, pin 4 and 5 are negative and pin 16 is positive. Memory is fallible.

    Disco 2 At the moment following a new chassis on Feb 1st I now have quiescent problem.

    I do know that the 38A Range Rover took 1 minuets to go to sleep as I had to watch one such vehicle go to sleep! The 38A RR sleeps in steps from about 20A, took 2 or 3 seconds to drop to a few amps, (it was nearly 30 years ago), but the last few steps were only a few mA until 40mA was the steady...

    Disco 2 At the moment following a new chassis on Feb 1st I now have quiescent problem.

    Thanks for reading and putting forward a possible answer, I may resort to connecting each circuit one at a time... I do have all sorts of drawings even a few harness drawings. I also know the team that built all of the electrical part of the vehicle and indeed I have built prototype Land Rover...

    Disco 2 At the moment following a new chassis on Feb 1st I now have quiescent problem.

    On the 6th of October I reinsured my D1. On the 9th the LHR shock absorber bracket fell off the chassis; vehicle off the road! I therefore brought forward my intention to change the chassis. Sixty days later, after a faultless start, I drove it onto a transporter. I picked my shiny D2 up on Feb...
