Relay looking diode box? What is that? Checked the alternator fuse?

In the fuse/relay block under hooh the "relay" marked alt, i took the cover off this "relay" and therse a diode and what looks like a ballast, where is the alternator fuse?

In that same fuse box there is a rectangular fuse with the clear cover that is installed diagonally in the corner. Its 2 feet are bolted on with 10mm bolt. If that fuse is bad the alternator is not going to charge the battery. Before you work on the bolts, disconnect your battery first.
