Default 2001 DTS Service Electrical System Warning

Service Electrical System comes on in dash, have checked codes and nothing shows up. Can clear codes and it will go out for a while. Battery is new alternator shows 150 % at Idle. Everything works Ok. Any Ideas to the cause of this? Don't trust mister good wrenches reasoning. Said computer needs changed out. High voltage draw.
