How do you check the starter/gen and voltage regulator? Thanks

First thing is to check your battery to make sure it is good.I'm not a gas guy but here are the procedures from the service manual:
Test Procedure 9 - Starter/Generator
LEAVE THE BATTERY CONNECTED WHILE PERFORMING TEST PROCEDURE 9.
1. Place the neutral lock-out cam in the SERVICE position, put the forward and reverse lever in the NEUTRAL
position, and chock the wheels.
2. Check that the wires are connected correctly and are tight. If they are not, rewire or tighten as necessary.
3. Disconnect the yellow wire from the DF terminal on the starter/generator. Cover the connector on the
yellow wire to make sure yellow wire will not short to ground. Then, using a jumper wire, ground the DF
terminal to the A1 terminal. Using a multimeter set to Volts DC (20v range), place the red (+) probe on
the positive (+) post of the battery, and place black (-) probe on the negative (-) post. Turn the key
switch to the ON position, and depress the accelerator to start the engine. Run the engine at full governed
speed. The reading should show voltage rising on the meter. If the voltage rises, see Test Procedure 10 - Voltage Regulator. If the voltage does not rise, see Starter/Generator Repair,
12 4. Reconnect the yellow wire to the (DF) terminal on the starter/generator.
Test Procedure 10 - Voltage Regulator
LEAVE THE BATTERY CONNECTED WHILE PERFORMING TEST PROCEDURE 10.
1. Place the neutral lock-out cam in the SERVICE position, put the forward and reverse lever in the NEUTRAL
position, and chock the wheels.
2. Check that the wires are connected correctly and are tight. If they are not, rewire or tighten as necessary.
3. Check the engine-governored RPM. The reading should be between 2625-2725 RPM. If it is not, adjust
the accelerator cable at the electrical component box (See Fuel System Section 14).
4. With the battery in good condition and fully charged, with proper ventilation run the engine for several minutes to bring the voltage regulator to operating temperature. Using a multimeter set to DC volt (DCV), place the red (+) probe on the large post of the solenoid with the red wire from the voltage regulator attached. Place the black (-) probe on the negative (-) post of battery. Turn the key switch to the ON position. Depress the accelerator to start the engine, and run it at full governed speed. If the reading is between 14.7 and 15.3 volts, the regulator is good. If the reading is lower than 14.7 volts but rising steadily, check battery condition (See Hydrometer Testing, Page 12-49). If the reading is lower than 14.7 volts and not rising, and the starter/generator is good; or if the reading is over 15.3 volts and continues to rise, replace voltage regulator.
