is it actually charging? use a multimeter accross the batt terminals whilst engine is running, you should be seeing around 14 volts, & more than 12+ volts with all electrical apliances on. if your not, check the fanbelts on, the wiring running from the alternator to the starter is intact & theres water in the battery, if that all checks ok, i would personaly still suspect the alternator new or not. with a charged battery (and idealy with a cold engine) the alternator (if at fault) will get hot when the battery has been conected for a while (half hour or so) with ignition off.

if the bulb on the clocks is blown it may not charge

is the wiring right?

i will have 2 look at the clocks 2moz,how many bulbs is there 4 the clocks.and the aternator i fitted came from my other xr2 that in useing 4 spares so i know it works and the battery came from my rs so i know that works.i brought the car from a mate it was stood 4 a while but he said he never had this problem.
