during a short ride today my check engine light came on along with my battery light, '07 heritage 2400 miles on it. i reviewed tech tips(thank you for a great site!) the codes that came up were P0562 (low voltage...?). another code, B1125 came up as well. can anyone shed some light? do i need a new battery? this winter i did use a tender to maintain the battery. thanks for any help.
