2008 DODGE SPRINTER 3500 Electrical System Problems

We've had multiple issues with starting the vehicle. After number attempts to eradicate the issue, I Google searched the problems and found that the y connect harness from battery to alternator and starter had been remanufactured for improvement 3 times.
