I have had some DTC issues and was told it could be due to low voltage. Can those with C5's post their normal running volts as read off the display. I can only get to 13.8 volts after a short or long run. With Lots of stuff runing I have seen as low as 11.7 and after a restart as low as 10.8. Anyone with experience in this area? :confused
