You could put your DVM on the 12V pin of the OBD2 port to see if it is a voltage drop in your wiring or if it is a misreporting by the device you are using. What are you using on the OBD2 anyhow?

You called it, it's my OBD-II reader. I get a solid 12.5V at the port itself with key ON. Time to try and explain to the wife why I need another car gadget...
On the plus side, the cheapo cig lighter voltage reader read at 12.4V. I'll use that from now on I think.
