WebIf you measure the voltage immediately after the end of a drive, it should be more like 13.2, and drop to 12.7 within a few minutes as the chemical reactions in the battery slow down and stop when you stop charging it. I suspect you are getting 12.7 immediately after switching off the engine and it drops to 12.1 in the same time scale. WebA high voltage drop indicates that the charging system has difficulty supplying adequate charging voltage to the battery. This means in turn that the battery has difficulty supplying power to the starting and fuel injection systems and other circuits during cranking and start up time. First, disable the fuel system by removing the fuel pump fuse.
