You are correct the small gauge wires cannot handle all of the current when at high loads. S4 and S6 most prone, the others, meh. One can get the mating connectors and make your own jumper to a solid ground with a more appropriate gauge wire, if not melted down.
Soldering them together means connecting 6 small gauge wires, which still leaves you with the high current travelling through one of them. While you're doing that, best solder in a good wire in at the same time... I'd say 12 ga. minimum. In other words, doing the same as the connector fix, but soldering instead of a connector.
