ive had my ford focus for six weeks now the problem is the battery light keeps coming on, it first came on after 3 days took it back to the garage where i bought it they charged the battery up checked the alternator and said they could not find any fault, picked it up and after 30 minutes the light came on again, took it back the garage but this time they changed a wire to the alternator and a fuse, got the car back had it for two weeks thought everything was ok and the light came on again, ive checked online myself to try and solve the problem and everything points to the alternator but the garage is adamant its not faulty and have no idea what to do next.
the garage will change the car but they dont have another focus so i was wondering
1) change the alternator anyway 2) would fords be able to find the fault if i took it to them 3) any ideas as to what it could be. 4) get ridp.s not sure if this should happen but when i start the car if the heater is set to 0 should the air recirc light be on.
if you need more info ill do my best to provide it.
thanks in advance for any help
Jon.
