I´ve gotta question on my 82 maxim 750 as well. I took the battery out a few months ago and have no idea how to put it back together. I have one black ground, one black coming from under my seat, and one red and my starter cylinoid. I don´t know the right combo to hook all of this up, but whenever I do try and turn my key to ignition, my bike makes a whirring noise... please help me I just wanna ride.
