Lynn and I drove a 1950 Chrysler Windsor, a 6-volt car for 30+ years until we sold it on in 2013. Many people feel that "6-volt headlights" aren't suitable for driving at night. They are with good grounds.
If you are hunting for less than perfect electrical connections, there are two things you can do. For power connections probe wither side of an electric connection and read the voltage, any voltage reading across that connection indicates a less than perfect connection.
For grounds I usually run a wire back to the power source ground and then with that connected to my volt meter I probe the local grounds and look for voltage. Once again, any voltage showing up indicates a less than perfect connection.
