Sredded alternator belt some months ago, spaggetti pieces in alternator on my 2007 , 2 months later it was fried, checked all fuses and hook ups, then got 2002 E55 alternator that was checked. everything work fine for 7 miles, 13,1 to 14 volt in display , Did 3 hard trottle pull , after about 8 min Then red sign Batteri in display, stop car. What can be the problem? Have weistec 180 crankpulley , tuned RPM limit set to 6500

can understand the first alternator blow, regulator blow 4 years ago on dyno, and changed regulator, all work fine til now. Can it be that 2002 e55 alternator is not right one, or what else can be?
