From one point of view it does looks like connections problems but I thought that there must be some voltage regulator just for such cases...
I noticed that that a ground point for the cluster panel instruments is the MPIV point. What is the location of that point?

I would clean every ground connection you can find, clean all fuses and holders. Make sure you replace the braided ground strap from the battery to body. It may look fine but it could be corroded inside the connections. Clean your battery connections. With engine off, your battery should read about 12.56 volts, 13.8 with engine running.
Also clean the ground lead from the engine block to body.
