As a matter of preventive maintenance I put external tooth washers, also known as 'star' washers, on the wiring ground points of my vehicle as I come across them or work on them. External tooth 'star' washers are commonly used in electronics to ensure a good ground connection. The sharp teeth on the 'star' washers bite into the ground stud and the wire ring terminals, making sure there is good metal to metal contact.
When I locate such a wiring ground point, I remove the nut and wires from the grounding stud. Then I clean stud and the wire terminal rings with steel wool. Finally I place a 'star' washer over the ground stud, then the wire terminal rings, followed by another 'star' washer, and finally the nut. Then tighten the nut securely.
Additionally, the wire terminal rings can be lightly coated with a cooper based anti-seize. The cooper based anti-seize is electrically conductive and will prevent corrosion/oxidation. This is actually done on high power radio transmission couplings. I use this technique on the ground points exposed to weather, like in the engine compartment.
