obdII code po560.. any help?

hey everybody.. for the past month or so my girls slk230 (98) has given me nothing but problems.. now i have a check engine light that reads po560 which is a voltage malfunction.. the car loses power @ random times and sometimes just dies.. the alternator died a few months ago and i replaced it with a bosch unit and everything was fine for a while. has anyone had any experience with this code.. i havent been able to find anything online

it is also throwing a secondary air pump code as well,

Have the battery checked and see if it is taking a charge. Also check the wires from the battery to the alt. and any ground wires.
Your secondary air system fault may be a bad O2 sensor, post the code if you have it. There may be an air check valve that is shot or a bad/broken hose related to the system have a look at those as well.
