Re: [Chrysler300] 6 Volt Breakers

[Sheldon Wotring <swotring@xxxxxxx>]

Hi
The voltage rating on a fuse or breaker concerns the possibility of too 
high a voltage arcing across the gap when it opens.
In this regard there is very little difference between six or twelve volts.
The current rating (amperes) is the thing that must be considered.
