Heres the story so far,the Car wouldnt start the other morning, so out came the AA man with his jump leads and set me off on my way. During that journey just a short distance from work the Bat tery light comes on, but the car still keeps on going. Then I had very single warning light comes on that was every put on this earth and just managed to limp the last few yards home with it.
I have so far replaced the Alternator ( with a 2nd hand one ) and a brand new battery, but still cant get rid of this battery light . My thinking is, could The Aux belt not be thight enough and causing this altanator not to working properly and Can the car still run without this belt ??? ( if snapped ) as so far I havent had any other lights on over the past two trips to work and back ( round trip of 23 miles altogether )

just replaced the alternator on my 2.2 diesel and the belt is self adjusting so that shouldnt be a problem and im sure that its the same belt that runs the power steering so if thats ok then the belt should be fine best bet would be with car running to get a test meter across the battery . should be just over 12 volt without engine running and approx 14 volt with engine running

There's a summary which might help.

Generally on the alternator you have the thick current charging wire and then the what was/is known as the exiter wire (thin one).
This wire when disconnected should result in no warning light. this wire earthed should put on the warning light.
If the warning light is on permanently indicates the wire going to earth somewhere.
A working alternator "back feeds" this wire and puts out the light.
