My 1954 Dodge pickup has a 6-volt battery. The positive terminal is connected to ground. Today, nearly ever other vehicle in service has a 12-V, negative ground system. This leads to many questions I'd like for you guys to think about and discuss.
Can this 6-V positive-ground vehicle be safely jump-started by a 12-V positive-ground vehicle?
If I wanted to install a modern car radio, what adjustments should/must I make?
