charging system help needed
 

I have an 88 LX 2.3 replaced battery because of not holding charge, it ran a few times but now I am not getting power to the starter, but I've replace the solinoid on the fire wall and tested the starter, all that is fine! it seems there may be a possible short because I get some pretty good sparks when I connect jumper cables but still just noise at the fire wall when I turn the key. It's got to be simple but I'm out of ideas, can anyone offer up suggestions?

Check the ground, both at the battery and to the frame.

is it still a stock alternator? I've had to replace mine once already
