    hi there
    My normally well
    Mannered range lost all power the other day
    Started with a couple of lights on dash then about 7 came on lights shut off intermittently and I drove for a further half hour then it just dies on the hard shoulder m11.
    It’s been compounded near stanstead
    As I had a flight to catch Any ideas?
    Key turning does nothing, anyone local can have a look? It’s been fine other than the suspension lights been been on and off thanks if you can

    Sounds like a loose connection somewhere. Start with battery clamps then earth points. Maybe the alternator is toast?

    Plus 1 , also need the voltage of the battery

    Standing 12.6vdc
    Once Engine is running at 2,000 revs with everything on 14.5vdc , can go up to 15.8 Vdc

    also with engine running set multimeter to AC volts , put a probe on each battery posts , should
    be 0 v, or max 0.5Vac, this test the alternators diode

    if alternator is req best to fit a denso as cheap copies will cause havoc

    if ur not mechanically minded contact a recovery service, like AA, RAC etc who can come out and do the tests for u and recover if so required

    u saying ref alternator seen a few posts where some don’t test the alternator , just fit a new battery then find alternator destroys new battery, also seeing the smart alternator can produce up to 15.8Vdc

    These new smart alternators seem an unnecessary complication although I can see why you would want that charge pattern.

    often wonder if its because of the increase in the amount of electronics fitted , many having in excess of 30 x ecus , where the old alternator changes voltage on speed these change voltages according to load on the system

    also makes it good fun when trying to track down errors , ie in some intermittent Vdc spikes

    Found out that having the gap iid and decent multimeter has been a godsend when tracking errors down on my D3

    But know ur exceptionally knowledgeable with landies

    The higher charge voltage is to cope the the typical short school run that these vehicles are mostly used for which is not long enough to keep the battery charged at the normal charge voltage:rolleyes:
