right my alternator light gave up so i checked the voltage output and was giving out nothing so i got one of a seat diesel and changed the pully and fitted it on and changed the conectors on the back to the bolt on type connected it all up and is charging fine now

now the problem i have is that the battery light does not come on at all anymore when i turn the ignition to the point b4 cranking and does not even come on when i earth the wire and the battery goes flat overnight

so could it be a a duff alternator thats draining backover thats flatening the battey

right sorted the drainage, i did the light between the earth strap test ant it turned out to be the new alternator lol so ill have to get it changed

but i still cant figure out y the batt light is not working iv even changed the led and the wire from the alt to the light( blue batt charg light wire) is working fine and carrying 12 v ok ?

LEDs are polarity sensitive. They only work one way round.
