alternator wiring??? 200 tdi

hi there i have just purchased a 93 200tdi disco, there is a problem with the charge light staying in dimly withe the engine running and rev guage not workingh under 3000rpm. i have looked at the alternator and there is a wire loose the earth wire is attached but a wire joint to this wire and look as if it has come off, but where from??? ideas very welcome.

ps. i have done a search can find what colour wire does wot but not exactly where they should be attlached.

ok errr... this has been the probem since i brought the car last friday. i have used it this evening only about 7 miles to a friends house problem was the same on the way there, on the way back battery light went out and rev gauge worked normally, apeared to have fixted its self

but now battery charge light comes on when i turn off engine and stayes on with keys out of ignition. and i havent touched any thing yet! any ideas????

Yer alternators fooked, gerra noo un.

wot ee sed ^^^^^^^^^^.

ok cheers fot the help guys. i will look at gettting a new one, quick thought will a standad alternator be ok, as it has twin battries?

that will have to go on the 'todo list' as batteries dont seem to be loosing any charge as yet, and i doing the clutch tomorrow a will need more money for alternator lol

The alt might be charging ok, just that it don't realise it's charging perhaps.

I got one for my 3.5 v8 from euro car parts, 38.50


Don't know if it's the same part on the diesel...?

after doing my clutch change this weekend, left door open all day it flattened battery so had 2 jump it off the van. Took it for a 5 minin drive then left it running for 20 mins. tried to start, but battery dead. So it looks as if i need to part with some money for alternator sooner rather than later , probly order one online tis evening or tomorrow. does any one know if standard alternator is ok with twin batteries???
