TM 5-3805-262-343-4. ALTERNATOR REPAIR (CONT)INSPECTION/REPAIR (SHEET 3 OF 5)i.Inspect rectifier bridge(23) for cracks and damagedterminal studs or threads.Replace rectifier bridge ifany of the above conditionsare seen, or if rectifierbridge does not pass thefollowing test:(1)(2)(3)(4)(5)(6)(7)(8)(9)Using pocket knife blade, carefully pry up diode connectors at terminalstuds. Replace rectifier bridge if any diode connector is cracked ormissing. Diode connectors must not contact terminal studs or each otherduring following steps.Set multimeter to X1 or diode check range.Hold multimeter red lead atone diode connector, blacklead on negative heat sink.Note multimeter indication,then move black lead to di-ode connector, red lead tonegative heat sink. Notemultimeter indication. Thereshould be one high multime-ter indication and one lowmultimeter indication.Repeat step (3)diode connectorheat sink.Repeat step (3)Hold multimeterheat sink. Noteabove at secondand negativeabove at third diode connector and negative heat sink.red lead at one diode connector, black lead on positivemultimeter indication, then move black lead to diodeconnector, red lead to positive heat sink. Note multimeter indication.There should be one high multimeter indication and one low multimeterindication.Repeat step (6) above at second diode connector and positive heat sink.Repeat step (6) above at third diode connector and positive heat sink.If both multimeter indications in any step (3) through (8) above are thesame, replace rectifier bridge (23).3-212Change 1
