hi all. new to the forum but not to tw's. i have an 09 tw and i let the battery go dead. i tried to recharge it but im pretty sure it went down so far that it wont take a charge. i bought a new battery but got the polarity mixed (neg on pos, pos on neg). i tried to start but nothing. when i realized i had polarity switched i corrected and now i still get nothing. any ideas? no clicks, no dash or headlights, nothin. can anyone help?
