negative ground systems have always been in use but some chose to use positive grounds as wires were poorly insulated and suffered from corrosion on negative earth systems but positive earth systems did not suffer as badly to corrosion (i heard somewhere Henry ford came up with the positive ground idea cant say for sure)
in recent times insulation is greatly improved and with bridge rectifiers instead of contact rectifiers which caused more uneven power flow to the battery most decided to use the same system putting everything on negative ground for simplicity but you will always have one oddball who uses positive ground just for the sake of being different

Why are electrical systems grounded?

Electrical systems must be grounded for the devices to function. The flow of electrons that drive them are attracted to the opposite pole of the battery and will not go through an electrical device that doesn't allow them to get to that pole.

What is grounded electricity?

For safety reasons electrical systems are normally grounded (for example, an a.c. supply system's neutral is grounded at the transformer). By common consent, the ground (or earth) is then taken as being the zero potential point of reference, from which potentials in a grounded electrical system can ( Full Answer )

What is electrical ground?

Answer for USA, Canada and countries running a 60 Hz supply service.
