I had a problem with the starter cranking to slowly so I replaced it with a new starter and now it does nothing. I cleaned all the terminals tightened all connections and nothing. I also changed the throttle control cables and thought maybe it wasn't in neutral but i tried jumping the starter bypassing the solinoid and got nothing but alot of sparks. I was trying to jump it using jumper cables running off my truck battery. Could the battery not be enough to turn the starter? I was told to check the kill switch but I'm not sure where that is and i did reset the breaker and still nothing. any suggestions?
