just taking new car out on the street for a few small test drives before bring it to the track.finding the batt loosing charge pretty fast down from 100% to 70% after about 3 or 4 miles.it has a new deka agm batt and a east coast 120 amp super mini with a 5 inch pulley on the crank.it had a #8 wire going back to the batt switch from the alt.so just to try i put a #6 wire from the alt right to the batt stud on the starter so its a shorter run with large wire and its doing the same thing.car has a pro star 500 pump,msd 7531,eletric fan/meizzer water pump/eletric shifter etc.checked the volts at the back of the alt 13.5 @idle and 14.5 @ a little over 2000rpms.the batt is ground to the frame under the batt tray not sure if that would affect the charging running out of ideas.could it be just the low rpms on the street just isnt enough to keep up.thinking about a bigger crank pulley if there even made bigger than 5 inch for a moroso keyed drive mandrel.any ideas thanks?.sean
