electrical problems

[gervaised]

i've had a problem over christmas which has made me abandon my car (95 chim)over the christmas holiday. driving along, the dials will all go dead, and the battery light comes on faintly, and somethimes the rev counter will show 1000 rpm at all speeds. the battery stops charging, and eventually the car splutters, and cuts out. it's none of the connections, ie chassis earth/ starter. any ideas? the problem was intermittent, but now seems pretty permanent.
