Unterschiedliche Voltanzeigen ?

Bei laufendem Motor ist der Unterschied erklärlich , aber bei Zündung aus ???????

Hatte ich missverstanden...stimmt...wirklich ungewöhnlich.

Vielleicht eine Erklärung:

The voltages that your seeing on the DIC and dash gages are NOT a TRUE voltage from the battery! As far as I can tell (GM does NOT show you what all goes on inside the dash cluster in the service manuals. ) there isn't a wire that hooks the gage meter DIRECTLY to the electrical charging system. The voltage readings comes from the PCM and goes to the IPC on a serial data line as a digital signal and gets interpolated as an analogue voltage. In fact, there are other displays on the dash that are interpolated from digital serial data buss signals.
