Okay I have a ’46 2 ton with a 216 the system aperies to be the original 6 volt. The question came to me as I was posting my other electrical questions. How can I tell if the system is still 6v or has been half converted to 12v? Being in Alaska it is common to just patch things together and half the wires look like original 6v thick crumpling wires and some look like newer 12v wires. How do I tell if the generator, starter, all the electrical parts are 12v or 6v?
