Source for 30 amp ceramic fuse in the US?

[MLA]

As a recent owner of a Fulvia Sport, I am looking for a source in the US for the 30 amp ceramic Bosch style fuse. 16 amp fuses are plentiful, but sourcing a 30 amp fuse of this type is proving a challenge. Can I use a 25 amp fuse (easily found) in the place of a 30 amp?

I am not aware of any 30 Amp fuse in a Fulvia. Where is it?

I found the information in the Fulvia 2nd Series Coupe/Sport owner's instruction manual, page 31.

Thanks for the info. I looked it up. It lists even two 30 Amp fuses for the Zagato. The extra one must be for the electro motor in the rear.

Correct me if I am wrong. I am sitting at home in front of a computer screen. I am not in the shop. I guess one of the 30 Amp fuses is #9. The rear window heating is connected to #9 and that is a heavy current user. After all those years not all wires will be working. I would try the 25 Amp. The second 30 Amp fuse in the Zagato is probably #7 to which the electric motor at the rear is connected. You could also try the 25 Amp.

So, if you want to experiment with 25 Amp fuses I think it might work. Have some extra spares with you.

I am going to try the 25 A fuses in place of the Lancia recommended 30 A fuses. I have found a source for German made NOS 25 amp fuses so I should have plenty to experiment with.

The more I look into the question of the proper fuses for our Lancia Fulvia Sport, the more I am getting confused. The Fulvia 2nd Series driver's Instruction Book states:
"Eight 16 A fuses (yellow) and one 30 A (red) (for sport, seven 16 A fuses and two 30 A ones) protect the various circuits, as indicated on the fuse box cover." Or: Yellow = 16 A and Red = 30 A

In every other source I have looked at the Bosch style ceramic torpedo fuse color/amperage codes are:
Yellow = 5 A
Red = 16 A
Blue = 25 A
Green = 30 A

Can someone explain why there is a discrepancy between Lancia's fuse color/amperage code and the rest of the world's?

I don‘t know the reason but depent on history of Lancia i would like to say: Because it's Lancia
