luke analog/digital multimeters can also be
used for checking automotive capacitors (condensers). The movement of the bar
graph will show that the DMM is charging the condenser. You'll see the
resistance increase from 0 to infinity. Be sure the switch the leads and check
both ways. Also make sure to check condensers, both hot and cold.

Fig 13 - Checking Condenser Leakage Check for leaking
condensers with the Ohms function. As the condenser charges up, the
resistance should increase to infinity. Any other reading indicates that
you should replace the condenser. If the condenser is on the car, make
sure the points are open.
