Looks to me you have something cutting/wearing spots threw the insulation.
Check to be sure the wire is not getting pinched or rubbing against moving parts.
The waterproof box is crimping the wires. The wires are fine but you can not crimp them so tight. You need to readjust the wires in the box for more clearance.
