Hi,how are you?I would have the starter tested,even if the starter is cranking the vehicle,it can still be shorting out and killing your battery,since the cable is running directly from starter to battery.I have come across this issue before.

Expert:  Mike Kelly replied 4 years ago.
I would not recommend doing this,there is high voltage there,and it could really injure you,i would suggest removing the starter and then having it tested,thank you.
Customer: replied 4 years ago.
Hey Mike, I replaced the starter and the system is still not charging.
Expert:  Mike Kelly replied 4 years ago.
Ok,lets move to the alternator wiring harness,look for any burnt or broken wires,also check all fuses in the vehicle,to look for any blown.

That has all been done.
Expert:  Mike Kelly replied 4 years ago.
Ok,since you have confirmed that the wiring is fine and fuses,you are going to need to check the voltage regulator on the vehicle,i could not find a diagram for this but they are generally located on the fire wall under the hood.
