Alternator Testing and Repair in South Windsor, CT
We measure charging voltage and current under load before deciding the alternator needs replacement.

Alternator repair in South Windsor begins with a charging system test, not a guess. Dim lights, a battery light, a whining noise, or a battery that keeps going dead can all point to the alternator, but a worn belt, a bad tensioner, a corroded cable, or a weak battery can cause the same symptoms. We test output at idle and under electrical load, check the belt and pulley, and measure voltage drop on the charging cables. Many vehicles also need the battery tested, because a bad alternator often damages it.
