Hi got a 2013 BR. Went out a few weeks ago and battery wouldn't crank motor. alright so go get new battery put it on and it never cranked. Figured it was just bad.... go take it back and get another put it on and crank it barely but does crank let sit for couple days come back now it wont start again. Take back 1 more time and get a bigger gel battery with almost twice the cranking amps as other put it on and crank it and figure it finally fixed comeback few days later and same thing!!!! what gives any help will be greatly appreciated Thanks
