Battery charging problem

Hi,
I have an odd electrical problem with my 96 HDJ80. The battery is not
charging. I have had alternator problems in the past and all the dashboard
lights have come on. This time is different, the charge warning light and
the timing belt warning light do not even come on when you first turn on the
ignition. I can not remember how many lights normally come on when you turn
on the ignition but I am getting F + R Diff lock and airbag coming on for a
few seconds - normal behaviour - abs, hand brake and turbo but nothing else.
I have checked all the fuses in the under bonnet box and the dash board box.
Has anyone seen this before? Any ideas what to check next?
Thanks
Ian

Morning Ian,
My first thoughts is that it could be a wiring problem - check all the leads from the two batteries to make sure that the connections are solid at either end.
Assuming that they are OK, try swapping the batteries to see if that makes a difference - you may have problems with one of the batteries failing and unable to receive a charge - swapping the batteries should highlight this. Either that or measure the voltage across the battery terminals.
Give that a go and then et us know how you got on.
Regards
Julian

Ian,
The batteries are your first check, as Julian said. You could try
putting a charger on them and then trying your ignition, the charger will be
good enough to power the lights, don't try and start the car though. Pulling
out and replacing the Alternator plug is worth a try, these plugs are a bit
crafty, they feel as if they are plugged in when there is about 3-4mm left
to go. This can cause all kinds of lights to malfunction.

How do you know the batteries aren't charging? First thing is to check if
the alternator is producing a voltage, put a voltmeter on the battery
terminals. Check voltage without the engine running, check voltage with the
engine running.
If you have a DC clamp ammeter check with that.

I had a similar problem a few months ago (with the warning lights that you
mention below staying on permanently)
Turned out to be the stator on the alternator. Replacement alternator fixed
it.
Check the obvious such as the plug in electrical connector on the alternator
to ensure that there's a good connection there.
Suggest that you then put a tester on the alternator output to see if it's
putting any charge out.
Otherwise it's probably rebuild or exchange alternator.

Thank you all for your suggestions.
Turned out to be the alternator. This was low down on my list of suspects
because it is a 3 month old genuine Toyota exchange unit. When the last one
failed the dashboard lit up like a Christmas tree, this time half the lights
failed to come on when they normally should.
