the fuse on the card with the link is standard.
Looks like they have split the load from for the G.I. from 1 fuse to 2 fuses.

it shouldn't cause any dramas. but the fuses should be a lower value than what is in the manual, they only have around half the load compared to having all the G.I on 1 fuse

looks like they couldn't find the correct size fuse for the piggy back fuse on the power supply so they just used what they had.
