Tech Tip: Alternator And Battery Testing Diagnostic Tips
For some vehicles, it’s normal to see as high as 16 volts for long periods at a time. For others, it’s normal to see as low as 13 volts. For some, a constant 13.6 volts is an indication of a problem.
Honda LIN Line Controlled Charging Systems
On older vehicles, the alternator and engine were never really connected. The alternator was internally or externally self-regulated to a voltage, but that was it.
Alternator Pulley Diagnostics

Be Careful When Handling Alternators with Floating Stators
Some original equipment alternators made in recent years feature a “floating stator” that is more sensitive to proper handling than previous designs. Previously, the stator — the set of windings that surround the rotor — in most alternator designs, is press-fitted or in a tight tolerance. In recent years, however, some manufacturers have chosen to
Avoid Alternator Returns, Make Peace With Your Parts Suppliers
If the charging voltage is low, or the alternator isn’t putting out enough current to keep up with the electrical loads that are placed upon it, don’t automatically assume the starter or alternator is bad and needs to be replaced (unless you’re bench testing the unit out of the vehicle). Many times an alternator is
