Observe displayed value. Displayed values are in milliohms.
Expected minimum value is25 milliohms.
NOTE: If .18.104.22.168 is displayed, starter circuit resistance is more than the range of the VTM and cannot be measured. If E013 is
displayed, then check battery connections and correct as necessary. Repeat test procedure. If E013 persists after 3
tests, VTM cannot perform test.
