Bob you replied earlier:
Quote: | (2) Im confused about the wire between the connection terminal for the
main bus and the DC power master switch. Why have a wire with a
fusible link coming off the bus connection terminal when you could just
have the wire hooked up to the bus with a standard fuse like the other
circuits? I know Im missing something...

I you choose to use a fuse block in conjunction with an alternator
control having a crowbar ov protection system, you'll want a circuit
breaker on the panel which is an EXTENSION of the bus from the fuse
block to the breaker. The time constant of fuses is MUCH too fast to
run upstream of a breaker during the crowbar event . . . hence
the fusible link.
Bob . . .
In a previous post, I understood you to say that you could normally
substitute an appropriate fuse, 7a in this case for a 22g fusible link. I
take it from the above that there are instances where you want something
slower than a fuse which is the purpose here for the fusible link and you
would not want to run from the CB directly to a 7a fused slot. True? If so,
are there other instances to be aware of?
You also make the comment specifically as it applies to crowbar OV
protection systems and I see it with the crowbar on the 6/1/05 version of
Z13 using a ford regulator. I assume but am not sure if this also applies
as well if using the B&C LR3 regulator with internal OV protection shown on
earlier versions? ?? (I "was" fusing this one also)
Thanks for your patience!
