Templar M keeps draining battery

[NYCDiesel]

Hey guys, my templar's battery died last week so I ordered another. I installed the new battery, bike started, ran great but than as soon as I killed the engine the battery was completely dead again, really annoying. I'm guessing its the rectifier, but when I attempt to kickstart it the dash lights up for a second which makes me think the rectifier is OK. Would really appreciate any help, thanks
