  2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit.
  3. Disconnect the load.
  4. Select the MIN MAX function on the DMM.
  5. Connect one lead of the DMM to one end of the circuit to be tested.
  6. Connect the other lead of the DMM to the other end of the circuit.
  7. If the DMM displays low or no resistance, the circuit has good continuity.
