hi guys

i've just picked my fiesta turbo up from the bodyshop and i've got a strange problem with it when the ignition is turned off the battery light on the dash is staying lit and draining the battery when the car is running it seems fine.

i've checked the battery voltage, and checked the voltage at the starter motor and the alternator and the alternator seems to be charging ok

i'm sure it's something really simple but i've checked everything i can think of

SOMEONE PLEASE HELP!!!!!!!!!

PAUL
