Just read my reply to your post and something did not make sense. You said you hooked the + post on the battery to the starter, and the - post on the battery to the frame. Do you not have a cable or strap connecting the - post of the battery to the frame? If it is 12V negative ground you should. Putting the jumper from the + post of the battery to the starter should bypass the switch and it should crank without needing a jumper cable from the - side of battery, that should be connected already.
