WARNING: This page is about a different car, the 2004 Mazda MPV, 2003 Mazda MPV, and 2002 Mazda MPV. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION: Operating electrical loads while measuring the back-up current can damage the circuit tester.

Verify that the ignition switch is off and that the ignition 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 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.
