Hi, on cold morning my astra J 1.7 110 2010 has a squeak which goes after 5 minutes or until warm then after the squeak has quietened you can hear this strange clicking tapping noise only when lights, radio on etc like its coming from the alternator which is still original but giving good reading on battery and charge?
