9-2013 9. Troubleshooting
8. Check air filter cleanliness; replace the air filter as necessary.
9. Check for a blocked or damaged exhaust system: repair or replace exhaust components as
necessary.
10. Measure AC frequency while changing engine rpm to determine if frequency response
matches engine rpm response.
11. Propane Models
a. When ambient temperatures are less than 40°F vapor withdrawal Propane tanks
should be at least half full to provide proper vaporization rate.
b. Propane having more than 2.5 percent Butane will not vaporize in ambients at less
than 32°F; use HD-5 grade Propane.
c. Run the generator set on shop fuel supply; verify tank level and fuel line condition.
12. Measure steady DC voltage at the fuel solenoid while the generator set is running; repair
wiring as necessary.
13. Verify clear vent hose.
14. Check the generator set fuel lines for damage: replace fuel line as required.
15. Measure fuel supply and regulator lock off pressures.
16. Check the governor, actuator, linkage, and spring for debris, damage, and looseness:
readjust and repair as necessary.
17. Verify that the spark plug cables are secure on the spark plugs: reconnect or replace as
necessary.
18. Inspect the ignition kill lead (J1-12) in the harness and at connector J1: repair or replace
the lead, terminal, or pins as necessary.
19. Measure the spark plug gap: set the gap or replace the spark plugs as necessary.
20. Verify ignition spark condition.
21. Inspect the spark plug leads, kill lead terminals at magnetos, and measure the magneto air
gap: replace the terminals, set the gap, or replace the magnetos as necessary.
22. Measure the temperature of the air intake and temperature rise across the generator set;
remove blockage or prevent air recirculation.
9.24 Control Card Failure - Fault Code 35
Logic: EEPROM (programming variables) error during self test
Possible Causes: Faulty program
Diagnosis & Solution:
1. Verify that the Last Fault is FC 35: Yes, continue diagnosis; No, troubleshoot actual last
fault.
2. Replace the control.
