Back-up current
- Verify that the ignition switch is off and that the key has been removed.
- Disconnect the negative battery cable.
- Measure the back-up current between the negative battery terminal and the negative battery cable.
- If not within the specification, measure the back-up current while removing the fuses one by one from the inside of the main fuse block and the inside of the fuse block.
CAUTION:- Operating electrical loads while the back-up current is being measured can damage the tester.
Standard current
- 20 mA max.
- Inspect and repair wiring harnesses and connectors of the fuse where the current decreased.
