Well, I just recieved a ofna starter box that I bought off of ebay and it is the one with two motors in it. I hooked up a battery to this starter box, using the switch that it comes with and I didnt get anything. So I hooked the motors up directly to the battery bipasing the switch and both of them run but they dont spin very fast. And I was even using a car battery like your supposed to. The car battery was full with juice, and I know that because that is the car that I drive everyday. So I dont really care if I have to bipass the switch everytime but I want to know why the motors spin reallly slowly and then they almost die after awhile. Also these are BRAND new motors. Can someone help me.
