    2. CAUTION: Operating electrical loads while measuring the back-up current can damage the circuit tester.
  2. Disconnect the negative battery cable.
  3. Measure the back-up current between the negative battery terminal and the negative battery cable.
    • If the current exceeds 20 mA, remove the fuse in the main fuse block and the fuse block one by one while measuring the back-up current.
    • Inspect and repair harnesses and connectors of the fuse at which the current reduces.
