Battery light on dash

[Busboss]

Hi everyone I recently had a gearbox fault light come on and at the same time I got a battery warning light , I took the car into jaguar and they diagnosed a gear box sleave leak it's all fixed now but I still have the battery light on. The car is driving get great and starts first time all the time it doesn't drain  when lights are on or any other electrics any ideas would be appreciated

Hi

Have you checked it with a multi meter

check the battery voltage, should be over 12 volts, not running, with engine running 14 volts to 14.5 volts

if you have over 14volts check the connections on the back of the alternator, battery warning light is operated by the alternator

any thing under 13 volts with the engine running and you have a problem, check alternator belt is tight

cheers
