Those are fuse holders for 4A fuses. They are for the ammeter. Heres a diagram with fuse holders shown with arrows.

Those are in line fuses - one is for the ammeter, not sure on the other.

I think they take a SFE4 fuse. You should be able to replace them with any in line fuse of similar amperage. They are similar to a fusible link, but replaceable.

Here is a link for the elec. diagram:
