Generator Output Test: Notes
- Connect voltmeter in series between battery positive and negative terminals and ammeter between generator "BAT" terminal and battery positive. Place a 10 ohm, 6 watt minimum resistor in series with generator No. 1 terminal and battery positive terminal. Connect jumper wire from battery positive to generator No. 2 terminal.
- Slowly increase generator speed and observe voltage. If voltage is uncontrolled with speed and increases above 16 volts, check for grounded brush clip as described under Regulator Output Test "Overcharged Battery" step No. 2. If not grounded, replace regulator.NOTE: Battery must be fully charged when making this check.
- Connect carbon pile rheostat across battery terminals. Operate generator at moderate speed and adjust carbon pile to obtain maximum current output. If output is within 10 percent of output stamped on generator frame, generator is good.
- If output is not within 10 percent figure, ground generator field as outlined in Regulator Output Test "Undercharged Battery" step No. 3. Operate generator at moderate speed and adjust carbon pile for maximum output. If output is within 10 percent of rated generator output, replace regulator.
- If output is not within that figure, fault lies field winding, diode trio, rectifier bridge or stator.Alternator Performance
