Checking for excessive resistance in the starting circuit is being discussed. Technician A says connecting a voltmeter across the ground cable from the battery to the ground connection of the cable is the preferred method. Technician B says connecting an ohmmeter across the positive battery cable after it has been removed from the vehicle is the preferred method. Who is correct?
A)A only
B)B only
C)both A and B
D)neither A nor B
