Hello I will help,
9.2 is not much, what are you grounding to? The frame?
Can you check from the negative post of the battery to the frame with the headlights on to see if it shows more than .5 volts?
That is with the headlights on? How about if you turn the blower motor on?
You should have some small voltage there, if you have a 2 volt DC scale use that
