ATV Polaris Sportsman 850 TPS Tool and Adjustment

My 2011 Polaris Sportsman XP 850 had a rough idle when it was hot and backfired at times. I found out that the Throttle Position Sensor (TPS) might be out of adjustment. I found plans and a description on how to build a 5 volt power source that can be used with a voltmeter to adjust the TPS. None of the information showed the completed connections for the 5 volt power supply so I decided to make this video to help others that might be working on this. The adjustment I made, before making this video, fixed the problems.
