Im installing a small 10 watt radio on my scoot,it has a yellow wire,a red wire and a ground my question is what wire is positive for ignition the manual only has color and not if there negative or positive,i can get to work with bike off but soon as i start bike it cuts off,not off power wise just no music plays but lcd screen stays lit no sound soon as i turn bike back off and cycle power button for radio sound comes back and all is fine and body any help would be great im stumped thanks

maybe if you looked at a wiring diagram it would help?
links are located at the bottom of the forum home page

also what does your multi meter say ? you must have more
than one hot wire there..

Multi meter says 13.20+ with bike running,i got radio red wire to red with white stripe and yellow from radio to orange wire at ignition switch,i did look at the links but nothing about if wire + or - i used a multi meter to find what was hot at on,radio has a aux output so u can hook a mp3 player up,when i plug that in it works fine drove to and frm work with no issues,its just when i switch to radio no sound and radio resets back to 87.5 and no button movements does anything,dont make sense,i got plenty juice im stumoed ,and when i turn bike off with key to the " on"  position radio works flawless!!!!
