No Steve. The load on the gears is not affected by 12v or 6v.
It is the electrical power consumed by lights etc that loads the gears.
Power is in watts, and watts is volts x amps.
To give the same brightness of light a 6v bulb will be lower resistance and allow more amps to flow. Less volts with more amps gives the same brightness and the same load on the gears.
If you want less load on the gears then whether 6v or 12v makes no difference. Changing to LED lights reduces the amps and reduces the load.
