ALTERNATOR 10 Amp Fig. 216 - Testing Stator Coils for Continuity Fig. 217 - Testing Stator Coil for Grounds CHECK STATOR ASSEMBLY (OUTPUT VOLTAGE) If there is no current flow on the DC output side of regulator, check to insure the stator is functioning. Disconnect the regulator to stator plug, Fig. 219. Attach the leads from a #19236 VOA meter to the pins in the stator plug. Start and run the engine at normal operating speed (minimum 3200 RPM). The voltmeter should read at least 17 volts (20 volts at 3600 RPM). If meter does not show a reading, check the stator for an open or ground condition, Fig. 217. If voltage is present, first make sure there is continuity in the charging lead (rectifier to battery wire), Fig. 218. If continuity exists, replace the regulator. Fig. 218 - Checking Continuity of DC Output Lead to Battery Fig. 219 - Checking Output Voltage (AC) OVERCHARGING If battery seems to be in a state of overcharge (boiling out of water), first check to ensure the battery is not vibrating or shaking in the battery holder or case. If battery seems secure, check battery voltage. If voltage is more than 16 volts, it is being overcharged. This could be either the fault of the battery which is due to a high resistance or the regulator which is continually putting current into the battery. If the battery is replaced and the voltage still is above 16 volts, this would indicate the regulator ‘is at fault. Replace the regulator in that case. If upon replacement of the battery the voltage stays below 16 volts, this would indicate the battery was at fault. 67
