Q: Charging system

asked by on February 24, 2017

The battery was full 12v. I'm turned on engine. But the dash board did not have any light on. Only door open signal and head lights. I measured how many volts there in the battery while the engine run...same 12v. So I guess, not enough electric power to run all functions

My car has 197654 miles.
My car has an automatic transmission.
