2000 Isuzu Rodeo LS, 2.2 DFACTORY OEM SERVICE PROCEDURE

Rectifier (Diode) Assembly

Using an ohmmeter, check continuity of diodes in both directions. See Fig 1-Fig 3 . Continuity should be present in one direction only. If there is continuity in both directions, diode is shorted. If there is no continuity in either direction, diode is open. If any diode is defective, replace entire rectifier assembly. See OVERHAULΒ .
