Alternator or Starter in St Paul
If your car keeps dying after a jump, the alternator is a likely suspect. We come to your St Paul location, test the charging system, and tell you alternator or starter before any work. We also handle starter replacement when that is the real problem.
A new battery that still will not start points to the alternator or starter, and we diagnose it on-site. See our battery replacement page for charging system basics.
If the problem is not the charging system at all, our diagnostics page covers the full scan.
