Hi. I can't work out what this guy is. Big wires are to the battery switch I think (bit of a mess back here) and the small wires directly to the battery. Could it be some sort of terminal post?
Could be a terminal post. However, the big wires with those endings are for engine cranking/starting. The little ones might be to a push button, and here will be a relay to the starter motor. Otherwise, an exciter circuit to the alternator for the little wires.
