Is this a 3 or 4 wire system? Are the Neutral and grounds separated or bonded? It sounds like when you make the connection mentioned, you are giving neutral current another path to flow back to the source.
That is why the spark is larger when more lights are on, because the neutral current is higher.
A picture may help to explain what is going on.
