Yes. In electrical systems, resistance in a circuit means that some
electricity is converted to heat. If too much resistance is in a
circuit, the voltage drop may be significant to the devices (and hence
make them work unreliably, or not at all.) Additionally, if there is
too much resistance that should NOT be there, the heat generated may do
bad things, like melt switches (aka headlight switch), or wires, or
even cause a fire.
