i think after the three flashes you push the stop again and it gives you the second number. mine is flashing 36 but i have not had time to fix it. any ideas?
GENSET STOPPED WITHOUT FAULT CONDITION – FAULT CODE 36
WARNING Some genset service procedures present hazards that can result in severe personal injury
or death. Only trained and experienced persons with knowledge of fuels, electricity, and machinery
hazards should perform genset service. See Safety Precautions.
Logic: Quadrature frequency was less than 17 Hz (1020 rpm) when no other fault condition occurred
Possible Causes: Auto Gen Start (AGS), fuel supply, air fuel mixture, exhaust system, loads, Inverter/Char-
ger, choke, demand regulator, carburetor, generator drive system, generator windings, ignition, wire connec-
tions
Diagnosis & Repair:
1. Verify that Last Fault is FC 36: Yes, continue diagnosis; No, troubleshoot actual last fault.
2. Verify whether AGS stopped genset: Yes, disable AGS or explain AGS function to customer (see
PSB-666); No, continue diagnosis.
3. Verify engine rotation manually: repair engine damage as necessary.
4. Disconnect genset control P1 connector, verify P1 pins are fully inserted and inspect pin condition per
PSB–676: insert, repair or replace pins as necessary.
5. Reconnect P1 connector and test run genset for fault occurrence: repair or replace pins in connector as
necessary.
6. Check air filter cleanliness; replace air filter as necessary.
7. Check for blocked or damaged exhaust system: repair or replace exhaust components as necessary.
8. Measure AC current while running genset with vehicle loads: identify faulty or short cycling loads.
9. Determine battery charge rate (typical default is 80 percent): if adjustable reduce to 30 percent.
10. Measure genset load capability with shop load bank.
11. Verify genset operation and outputs with Break-Out Tool 420–0603 and Instruction Sheet R1098.
12. Measure AC frequency while changing engine rpm to determine if frequency response matches engine
rpm response: repair damaged generator drive system as necessary.13. Gasoline Models
A. Vapor lock may occur in high ambient temperatures: operate in ambients at less than 120°F; verify
proper installation to prevent air recirculation; correct as necessary.
B. Measure steady DC voltage at fuel pump while genset is cranking: repair wiring as necessary.
C. Try to start genset on shop fuel supply: verify tank level and fuel line condition in vehicle.
D. Verify carburetor altitude setting: readjust as necessary.
E. Verify choke operation, setting and linkage damage: readjust, repair or replace as necessary.
F. Measure fuel pump pressure/flow: replace fuel filter or pump as necessary.
G. Inspect carburetor butterfly for binding: replace carburetor as necessary.
14. 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. Measure steady DC voltage at fuel solenoid and priming solenoid (if so equipped) while genset is
running; repair wiring as necessary.
D. Verify clear vent hose.
E. Run genset on shop fuel supply; verify tank level and fuel line condition in vehicle.
F. Check genset fuel lines for damage: replace fuel line as required.
G. Measure regulator lock off pressure.
H. Verify priming solenoid operation, if so equipped.
15. Check governor, actuator, linkage and spring for debris, damage and looseness: readjust and repair as
necessary.
16. Verify that spark plug cable is secure on spark plug: reconnect or replace as necessary.
17. Inspect ignition kill lead in harness and at connector P1: repair or replace lead, terminal or pins as neces-
sary.
18. Test magneto
A. Disconnect Connector P1.
B. Connect positive(+) meter lead to chassis ground.
C. Measure continuity to negative lead at pin P1–15 and P1–20: replace magneto as necessary.
19. Measure spark plug gap: set gap or replace spark plug as necessary.
20. Verify ignition spark condition.
21. Inspect spark plug lead, kill lead terminal at magneto and measure magneto air gap: replace terminals,
set gap or replace magneto as necessary.
22. Measure temperature of air intake and temperature rise across genset; remove blockage or prevent air
recirculation.
23. Dealers contact Distributor for technical support, Distributors contact factory for technical support.
