Hello to Germany.
There is a wire connecting the left to the right alternator. I believe that on my truck the original cable was broken as the previous owner bypassed it. But checking for continuity in that wire going from left to right would be something i would check.

The voltmeter has a resistor on it. If it is open or damaged the meter won't work. But first check the fuse for the voltmeter at the fuse panel.

Fuse #12 is the 24 volt fuse for the voltmeter.
