Hey guys,

Is there anyway to test the FSU to verify its integrity? My a/c works fine, but I read somewhere that "About 90% of the dead battery problem's" are solved by replacing this part. But I don't have any of the "uncontrollable a/c blower" symptom's, just a parasitic draw of about 4amp's....

Any thought's would be very much appreciated,
