Where does the charger plug in for the Yamaha Raptor 700R 12 volt

Could be fuel starvation caused by dirt in the filter/carburettor etc.

Try this site for your manual. https://searchmanuals.net/search7/?keyword=%2Bowners+%2Bmanual&gclid=Cj0KCQiAzePjBRCRARIsAGkrSm4hwGgMJ4loxVKnk_d9loNSyMnzjcinCTYKx6DBNotuk4W7EdNURhoaAggqEALw_wcB

you can but it'd be better to fix the starter

faulty switch/toggle
loose wire to motor
battery not holding charge
belt driven

Assuming the Raptor does not start:
The main fuse and the fuse box are located under
the seat. There should be a spare fuse there also. Turn the key to
OFF and turn off all electrical circuits. Replace any blown fuses.Turn the key to ON and turn on the electrical circuits to check if the devices operates. If the fuse immediately blows again, have a Yamaha dealer check the electrical system.
I found this in the online owners manual at this site:

Maybe the manual will help troubleshoot your problem.

too much gas.

Can someone please tell me why my grandsons Yamaha raptor 700 runs fine and all of a sudden loses power? Someone told me we needed a new pedal. Ordered that and still does the same thing. So frustrating. Thanks
