[Land-speed] Electrical Question (Sunbeam wiring)

[drmayf]

Do alternators generally have fuseable links on the wire that goes to 
the battery? If so, is it sized according to the alternator output? Ie 
woul a 100 amp alternator use a link that is 100 amps? What about a 
circuit breaker?  Now at the back of the Sunbeam where all the hot wires 
come together, I would like to add circuit breaker protection.  Again, 
how do I size it? Do I add up all the loads as if the alternator is not 
running and size it that way? When the motor is running and the alt is 
on then it takes away some of the need for the battery to send amps up 
the wire. So It seems like the worst case would be when the motor is not 
running but all the electical stuff is. Make sense? Oh, this does not 
include the starter circuit..

Thanks for you help..
