The problem is... low voltage... as stated before.

Why? The primary suspect is the voltage regulator. It is mounted on the altinator.

It also contains the brushes that the altinator uses to generate electricity. If one of these brushes is worn too low then you will get low voltage... as stated by the mechanic who tested the altinator. Another possibility is that your battery cables and battery teminals are corroded and not letting the altinator recharge the battery. Clean up inside your battery cable connectors and around the battery terminal. Then test to see if problem remains. If so then pull out the voltage regulator from the altinator and have a look at it. If brushes are worn low then replace the regulator.

Also do exactly as a former post suggests regarding cleaning up you grounds. Corroded grounds, like corroded battery cables, cause low voltage.
