10. A reading of 18 amperes (16 amp system) or 9 am-
peres (9 amp system) at 3000 RPM indicates the
charging system is functioning properly and the battery
being discharging current due to the amperage draw
on the system is greater than the amperage output of
the engine charging system.
11. If ammeter reads less than required amperes @ 3000
RPM, test the stator; refer to "Stator Ohm Test (Alterna-
tor Coils Only)". If stator tests OK, replace voltage reg-
ulator.
