Troubleshooting
Problem
Engine will not start
FUEL RELATED:
1. No fuel in tank or fuel valve closed.
2. Choke not in CHOKE position, cold engine.
3. Gasoline with more than 10% ethanol used.
(E15, E20, E85, etc.)
4. Low quality or deteriorated, old gasoline.
5. Carburetor not primed.
6. Dirty fuel passageways.
7. Carburetor needle stuck. Fuel
can be smelled in the air.
8. Too much fuel in chamber. This can be
caused by the carburetor needle sticking.
9. Clogged Fuel Filter.
IGNITION (SPARK) RELATED:
1. Spark plug cap not connected securely.
2. Spark plug electrode wet or dirty.
3. Incorrect spark plug gap.
4. Spark plug cap broken.
5. Circuit breaker tripped (electric
start models only).
6. Incorrect spark timing or
faulty ignition system.
COMPRESSION RELATED:
1. Cylinder not lubricated. Problem after long
storage periods.
2. Loose or broken spark plug. (Hissing noise
will occur when trying to start.)
3. Loose cylinder head or damaged
head gasket. (Hissing noise will
occur when trying to start.)
4. Engine valves or tappets
mis-adjusted or stuck.
Follow all safety precautions whenever diagnosing or servicing the equipment or engine.

Probable Solutions
FUEL RELATED:
1. Fill fuel tank and open fuel valve.
2. Move Choke to CHOKE position.
3. Clean out ethanol rich gasoline from fuel
system. Replace components damaged
by ethanol. Use fresh 87+ octane
unleaded gasoline only.
Do not use gasoline with more than
10% ethanol (E15, E20, E85, etc.).
4. Use fresh 87+ octane unleaded gasoline.
Do not use gasoline with more than
10% ethanol (E15, E20, E85, etc.).
5. Pull on Starter Handle to prime.
6. Clean out passageways using fuel additive.
Heavy deposits may require further cleaning.
7. Gently tap side of carburetor float
chamber with screwdriver handle.
8. Turn Choke to RUN position. Remove spark
plug and pull the start handle several times
to air out the chamber. Reinstall spark
plug and set Choke to CHOKE position.
9. Replace Fuel Filter.
IGNITION (SPARK) RELATED:
1. Connect spark plug cap properly.
2. Clean spark plug.
3. Correct spark plug gap.
4. Replace spark plug cap.
5. Reset circuit breaker. Check wiring and
starter motor if breaker continues to trip.
6. Have qualified technician diagnose/
repair ignition system.
COMPRESSION RELATED:
1. Pour tablespoon of oil into spark
plug hole. Crank engine a few
times and try to start again.
2. Tighten spark plug. If that does not work,
replace spark plug. If problem persists,
may have head gasket problem, see #3.
3. Tighten head. If that does not remedy
problem, replace head gasket.
4. Have qualified technician diagnose/
repair ignition system.

Do you have a question about the Predator generators 6500 Watt and is the answer not in the manual?
Questions and answers
Where is fuse box
The fuse box location is not explicitly mentioned in the provided context. However, the context does mention a "Case, Fuse Connector" and "Fuse, Rectifier (5A)," which suggests that fuses are part of the control panel assembly. Based on this, the fuse box is likely located near or within the control panel of the Predator 6500 Watt generator.

My pretador 6500 is used to power my RV but the lights keep dimming . It sounds nice and steady I checked the oil and fuel ect but it's still dimming.
Dim lights when using a Predator 6500 Watt generator to power an RV could be caused by several factors:
1. Overloaded Generator – If the total wattage of connected appliances exceeds the generator's capacity, voltage may drop, causing lights to dim.
2. Start-Up Wattage Demand – Appliances with motors, such as air conditioners or refrigerators, require extra power when starting, which can temporarily reduce available voltage.
3. Faulty or Loose Connections – Poor or loose connections between the generator and RV can cause voltage drops, leading to dimming lights.
4. Fuel or Engine Issues – If the generator's engine is not running smoothly due to fuel problems or maintenance issues, it may not produce consistent power.
5. Grounding Problems – If the generator is not properly grounded, it could cause unstable voltage output.
To troubleshoot, check the total load on the generator, ensure proper connections, and verify that the generator is running correctly.
