Battery works till I place on bike

I recently purchased a Magnum Metro Plus.
The battery, with full charge, will not power on when connected to bike. If I take it off, it powers up just fine. It did this when I first bought it a week ago.... and I thought it was a learning curve issue because after several attempts to power it up on the bike it finally turned on. And it worked fine all week. But last night I went to ride and it simply would not power on at all. Unless I took it off the bike...then it powered up just fine.
