i have a pulse adrenaline 125cc its not getting any power unless its connected up to a boost started but even then its still like its not enough power to start the bike.. there is no idicators or back light on this bike.. would that be the problem or would it be anything else ive tried charging the battery and im still not getting anything when i put the battery back in it.. ive also tried multiple batterys but still nothing.. if someone can get back to me via my email i will be very grateful!
