I just got my Matrix TR a couple of days ago. While trying to start it I broke the pull string. So I went out and bought a starter box OFNA crome top. When I try to use the starter box it wont turn the engine over the electric motor just comes to a dead stop and does nothing. I'm using the gator clamps to my GMC truck battery to power the ofna box. What am i doing wrong please help....
Frustrated.
