Where are you grounding the probe? At the battery? At the car frame? At
the engine block? You may get different results. If so that is the source
of the problem.
The first thing to learn about electricity is that the circuit has to
complete the circle. From the battery back to the battery. You can ground the
positive probe to the battery positive and then check the voltage at the car
frame and the engine block to see if you have issues with either of those
connections.

PS: I presume you are connected positive ground.
