How do you check for power to starter on polaris 400?

Remove the skid plate off the bottom of machine . Take a standard test light , hook the clip to a good ground and touch the probe to the post on the starter . Push the start button and the light should light . If the light works and lights but the starter doesnt work take a small hammer and tap the starter while holding the start button . If the starter workes then the brushes are shot on the starter and need replaced .If the light does not light on tester go to the battery and follow the leads to the starter solonoid . One side of the solonoid should light up without pushing start button , the other side will light up when the button is pushed.
