Sorry but I don't find what you are trying to explain very clear.

Is the negative cable still attached while you are doing this?

Re: sparks when attaching pos cable to battery

Normally, you should not get any spark when attaching cables. Check to make sure the key swittich is off on the control box. I'd disconnect the big red plug under the cowling (disconnecting the control box) and then try reconnecting the battery. You should get no spark. If you reconnect the red plug, and it continues to spark, the issue is in the control box or it's wiring harness. Possible you may need a new key switch. You might want to visually double check the fuse in the main harness by the starter solenoid.
