that's why all the lose wires, but they can just as easly cause a problem as prevent one. On a battery system I'm working on all the monitor wires are sleved to help keep them as part of the solution vs a new problem.
The monitor wires could cause a short if the insulation failed, but there's no evidence of this
from the pics and the monitor harness looks intact.
They probably use glass braid insulated wire, or similar, to prevent this...
