The Generator Surging

Before we dive into the specifics of Predator’s 3500 generator surging, let’s take a moment to understand what surging is and how it affects generators.

Surging is a phenomenon where the engine RPMs fluctuate up and down, causing the generator’s output to become inconsistent. This can lead to voltage spikes or drops, which can damage electronic devices or appliances that are connected to the generator.

Causes of Predator 3500 Generator Surging

Several factors can contribute to surging in the Predator 3500 generator, including:

Dirty Air Filter

A dirty air filter can restrict the air supply to the engine, causing it to run lean and surge. It’s essential to clean or replace the air filter regularly to ensure proper airflow to the engine.

Clogged Fuel Filter

A clogged fuel filter can restrict the fuel supply to the engine, causing it to run lean or rich, leading to surging. Replacing the fuel filter can solve this problem.

Low Fuel Level

If the fuel level in the tank is low, it can cause the fuel pump to suck air, leading to surging. Refilling the tank can solve this issue.

Stale Fuel

Old or stale fuel can cause the engine to run lean, leading to surging. It’s crucial to use fresh fuel or add a fuel stabilizer to prevent the fuel from going stale.

Carburetor Issues

The carburetor is responsible for mixing fuel and air in the correct ratio for the engine to run smoothly. If the carburetor is dirty or misadjusted, it can cause the engine to run lean or rich, leading to surging. Cleaning or adjusting the carburetor can solve this problem.

Troubleshooting Predator’s 3500 Generator Surging

Now that we know the potential causes of surging let’s look at some troubleshooting steps that you can take to diagnose the problem:

Check Air Filter

Remove the air filter and inspect it for dirt or debris. If it’s dirty, clean it or replace it.

Check Fuel Filter

Inspect the fuel filter for clogs or debris. If it’s dirty, replace it.

Check Fuel Level

Check the fuel level in the tank and refill it if it’s low.

Check Fuel Quality

Check the fuel for signs of contamination or stale fuel. If necessary, drain the tank and refill it with fresh fuel.

Check Carburetor

Inspect the carburetor for dirt, debris, or misadjustment. Clean or adjust the carburetor if necessary.

Check Spark Plug

Inspect the spark plug for wear or fouling. Replace the spark plug if necessary.
