If you're getting intermittent clicking, it means there's not enough battery juice to spin the starter, either due to a dying battery or insufficient connections. If the battery is good, another cause can be corrosion - that white flaky crap on the battery connections. It can also get down inside the cable insulation and rot through the wires. A loose ground explains the sudden dying. Follow your battery cable down to the frame and ensure the connection is tight and clean.
On the spark from the negative cable, are you certain you don't have anything crossed? Look for stripped/chaffed wires going to the positive side that may be making contact with the body or frame - that'll 'complete the circuit' and cause arcing.
Good luck.
