charging problem
 

i recently bought a new battery and new battery cables and the battery died when I was driving it. then i got the altenator tested it was okay. then i regrounded with better 2 guage cable. then i read in the forum a thread with the same problem but it said it was the starter solenoid, so I replaced that and I'm still having the same problems. and I have a question the cable hooking to the altenator should that be connected to the starter solenoid? any suggestions would be appreciated.
