Test Procedure 12 – Voltage Regulator, Continued:
3. Check the engine RPM setting to ensure that it is adjusted correctly. See Engine RPM Adjustment,
Section 14, Page 14-10.
4. With the battery in good condition and fully charged, run the engine for several minutes to bring the volt-
age regulator to operating temperature.
5. Turn the key switch to the OFF position, killing the engine. Use a multimeter set to 20 volts DC and 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 (–) battery post (Figure 11-39, Page 11-32). With the Forward/
Reverse handle in the NEUTRAL position and the wheels chocked, turn the key switch to the START
position to start the engine. Depress the accelerator to run the engine at full governed speed. If the read-
ing 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 Test on page 11-21. 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. See Voltage Regulator Removal, Section 12, Page 12-11.
TEST PROCEDURE 13 – GROUNDED KILL WIRE
See General Warning, Section 1, Page 1-1.
NOTE: Keep the battery connected while performing this test procedure.
1. Turn the key switch OFF and remove the key. Place the Forward/Reverse handle in NEUTRAL. Chock
the wheels.
2. Disconnect the engine-kill white/black wire at the bullet connector located next to the RPM limiter
(Figure 11-41, Page 11-33).
NOTE: Disconnecting the engine-kill wire removes it from the start/stop circuit.
3. Turn the key switch to the START position and release if the engine starts. If the engine starts and con-
tinues to idle, check the kill-wire for grounding, the kill limit switch, and the key switch. See Testing the
Engine Kill Circuit on page 11-15. See following WARNING.
