ALTERNATOR10 AmpFig. 216 - Testing Stator Coils for ContinuityFig. 217 - Testing Stator Coil for GroundsCHECK STATOR ASSEMBLY (OUTPUT VOLTAGE)If there is no current flow on the DC output side ofregulator, check to insure the stator is functioning.Disconnect the regulator to stator plug, Fig. 219. Attachthe leads from a #19236 VOA meter to the pins in thestator plug. Start and run the engine at normal operatingspeed (minimum 3200 RPM). The voltmeter should readat least 17 volts (20 volts at 3600 RPM). If meter doesnot show a reading, check the stator for an open orground condition, Fig. 217. If voltage is present, firstmake sure there is continuity in the charging lead(rectifier to battery wire), Fig. 218. If continuity exists,replace the regulator.Fig. 218 - Checking Continuity ofDC Output Lead to BatteryFig. 219 - Checking Output Voltage (AC)OVERCHARGINGIf battery seems to be in a state of overcharge (boilingout of water), first check to ensure the battery is notvibrating or shaking in the battery holder or case. Ifbattery seems secure, check battery voltage. If voltageis more than 16 volts, it is being overcharged. This couldbe either the fault of the battery which is due to a highresistance or the regulator which is continually puttingcurrent into the battery. If the battery is replaced and thevoltage still is above 16 volts, this would indicate theregulator ‘is at fault. Replace the regulator in that case.If upon replacement of the battery the voltage staysbelow 16 volts, this would indicate the battery was atfault.67
