I have 01 mustang gt just installed new underdrivepulleys pulleys started her up just fine driving for a good 20 minutes when it just died . Note I left the stock alternator pulley and just swapped the water pump pulley and crank pulley. Now I got the car battery jumped and it started but then died again battery gauge slowly went low. So I took the alternator out and tested at auto parts and failed. Should I get a new 130 amp or same 110 amp alternator? Also should I swapp the alternator pulley? Thanks any help appreciated
