Thread: 2.7 TDV6 Alternator Issues

  1. #11
    Hi Garry One thing to check before installing the alternator is to check how many v s are on the pulley I found out the hard way one v more on the new one too the old one. Not a hard job changing pulleys but when you have to take the alternator back out and put it back in its a punish. Cant understand how both alternators had different pulleys but same part number.

    New alternator now installed and after a couple of starts all faults have gone.

    Process is not as simple as the Disco3 UK site indicated - basic process was spot on but did miss a couple of little minor issues - like once the bolts are removed how to get the alternator out and the new one in - I have probably stressed the little rubber coolant hose that runs by the alternator getting it out so will be keeping a close watch for coolant leaks.

    Clearly an operational alternator needs to be in the system to stop cascading faults caused by communication errors - this is despite a fully charged battery in the system = yes the engine will sort of run and the gearbox will sort of work but even when battery voltage is 12.8 v, if the alternator is not working you get more than just a battery light.

    The old alternator did not have any burnt smell so windings should be Ok and probably just a rectifier failure - I might see if I can get a repair kit and see what happens.

    Thanks - for all the input - much appreciated.

    It might just need new brushes but if the diodes haven't failed then best to replace them (the diodes) anyway.

    Further to my remark. I bought a new alternator from Ashdown Ingram, just needed to swap the pulley from mine with a rattle gun. It is a D3 2.7 and has been driven around Australia without further issue. Cost was substantially less than anywhere else.

    The ones that Ashdown Ingram (and many other companies) sell are Denso knock-offs (OEX Brand) not Denso Brand (made in Taiwan rather than Japan) - mine came with the correct pulley.

    Glad to hear yours is running OK as I had a concern the quality might not be up to what was required.

    Cheers

    Alternator field pickup bouncing

    I have had issues with field pickups not making continuous contact at high revs but work at lower revs it may be worth checking
