For line-to-line voltage measurements (readings); with the disconnecting means closed and the motor-starter at rest;
With one test lead of the voltmeter referenced to the load side of the fuse in line 3, and the other test lead referenced to the line side of either the line 1 or line 2 fuse:
A fuse, a measure of 480 volts indicates continuity through the line 3 fuse.
A reading of zero volts or no voltage at this point indicates that the line 3 fuse is open, but it does not guarantee it.
Another voltage check is required.
