Back-Up Current

CAUTION: Operating electrical loads while measuring the back-up current can damage the circuit tester.
  1. Verify that the ignition switch is off and that the ignition key has been removed.
  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. See Figure and Figure .
    • Inspect and repair harnesses and connectors of the fuse at which the current reduces.
