I just bought a new ofna mbx pro, starting it with pull starter was a pain and the glow plug warmer was always dieing. So I bought a Q-worlds starter box with a power panel. It has the big single motor (not the small twin motors). It worked great the first time I used it. The next time out it started my brothers MBX and then the motor started to spin the wrong way! So it would try to start the engine back wards! All the wires are hooked up right, I never changed the +ves and -Ves coming off the 12v batt. I don't under stand how the motor would just start going the wrong way! Sould I just change the wires? will this wreck my starter box motor? Also some times it will kick back and go the right way for a few seconds then stop and spin the wrong way again. Its realy wierd. If any one could help me out I would be greatful.

Thanks....Josh
