If there is a blinking light on the Monster Jam Supercharge Speedway, turn the power switch to the OFF position, remove any debris from the booster, and then turn the power switch to the ON position. 

To preserve battery, if the playset runs for 4 minutes without any activity (no trucks pass through), the light will start blinking red, and the booster will turn off. To turn the playset back on, move the power switch to the OFF position and then back to the ON position.
