probably because the directions that comes with the box are wrong... it will spark if you follow their instructions, and ruin the swith and motor...so i wanted to know from someone who has the box and wired it right , with more experience than i have, because i`m new with starter boxes with switches ...i put enough money into my Cen Matrix...the motor is crap...bought a new novarossi and just want to get it going before the weather turns here..so there is more to it than just pos and neg...so thanks for all your help....by the way...don`t you have any other hobbies to tend to?...like blowing a bag pipe?[sm=lol.gif]...not to be rude or anything...but in my experience , there`s always a trick or two to everything
