⁽¹⁾	Back-up current is the constant flow of current present (for the audio unit, clock, PCM, etc.) when the ignition switch is off and with the ignition key removed.

⁽²⁾	Lower limit of current must be more than 0A.

⁽³⁾	Turn the following electrical loads on and verify that the voltage reading increases. (Headlights, Blower Motor and Rear Window Defroster)
