big 3 question(pics included)

Put this in the Big 3 sticky last nite but don't know how often that gets looked at.

If your car is running and your Alt+ to Batt+ was to short wouldn't you need 2 fuses, one at the batt and one at the alt...? If you only had the batt fused then that would blow but if your alt is still running then power is still flowing through that wire because it is now grounded through the short and therefore a fuse at the alt would be needed. Or am I missing something here.

Hope that is understandable.

the alt (specifically, the voltage regulator) would fry itself the first time it shorted = no more output.

I see.
