So, last summer, I went camping (awesome, right?). But guess what? My RV’s TV and oven just kept losing power! Turns out, my Predator 3500 generator was being a little naughty and shutting itself off. That’s when I thought, “Man, I wish I knew about these generator problems beforehand!”

Here’s the thing: generators can sometimes act up. Here’s a quick list of what can go sideways with the Predator 3500:

  1. Takes a lot of tries to start.
  2. Sometimes, it just won’t start at all.
  3. It can shut off on its own – so sneaky!
  4. Oops! It’s on but not giving any power.
  5. It can get too hot (like, overheating hot).
  6. Runs but seems a bit tired or weak.
  7. Problems with the carburetor (that’s a part of the generator).
  8. Doesn’t run smoothly, like a car with hiccups.
  9. Worst one? It stops while it’s running!

What Are Some Common Predator 3500 Generator Problems?

Imagine this: You’re in your RV, ready to watch a movie or cook something, but your TV, oven, fridge, and other gadgets start acting all weird. If that’s happening, there’s a good chance your Predator 3500 generator is having some hiccups. Let’s dive into some of these common issues:

1. My Generator Just Won’t Start (Or Takes Forever To)

We’ve all been there – you try starting up your generator, and it’s just not feeling it. Often, this happens because of a sneaky little part called the carburetor. When this part gets all mucky with dirt, gunk, or other yucky stuff, your generator can struggle to start or even need a bunch of tries (those annoying cranks).

Fixing The Grumpy Generator:

What I like to do is give the carburetor a good cleaning. A mix of detergent and water with a toothbrush usually does the trick. But hey, if you prefer using a rag or other solutions, go for it! And here’s a tip: peek between the carb and the engine block. If there’s anything stuck there, clearing it out should get things running smoothly again.

2. It’s On, But Where’s The Power?

Now, this is a sneaky one. Your generator is running, but nothing’s getting power. Most of the time, this has to do with something called the AVR (Automatic Voltage Regulator) or the exciter.

Getting Techy With The AVR:

If you’re not familiar with the ins and outs of a generator, you might want to leave this to the experts. But if you’re feeling brave (and have some experience), you can check out the AVR yourself. Grab a voltage tester screwdriver and inspect those capacitors inside. Spot a faulty one? You’ll probably need a new AVR. Depending on the kind you need, it might set you back anywhere from $10 to $80.

3. Sudden Power Outage

So, you’re chilling in your RV, and bam! Everything goes dark. Sudden power outages are a bummer, right? Now, there could be a bunch of reasons for this, but let me give you a heads up on what it might be.

Is The Motor Being a Drama Queen?

Your Predator 3500 generator, just like other RV generators, has a motor called a starter. Think of it like the heart of your generator. Sometimes, it can get a bit fussy, especially if its wires or cables aren’t feeling snug and secure. So if your power suddenly disappears, take a peek at those wires and cables. If they’re looking a bit loose, give them a good tightening.

4. Automatically Shutting Off

Okay, this is like when you’re in the middle of a movie, and someone hits pause. Super annoying! Almost all RV generators, not just our friend the Predator 3500, can sometimes decide to take a nap and shut off on their own.

Is It The Voltage Regulator Being Naughty?

There’s this part called the voltage regulator (or AVR for short). Think of it as the brain of your generator. If your generator’s shutting down unexpectedly, it might be giving you a sign to check on this little guy. First, inspect the wires connected to the AVR. Loose wires can sometimes be the culprit. I always grab my trusty wire strippers for any wire tasks on my RV.

No Luck With The Wires?

If everything looks tight, then it might be time to replace that AVR. You can get a basic one for a bit more than 10 bucks. But if you’re in the mood to spoil your generator, you can go for a fancier version, which might cost you up to $80.

5. Overheating

Let’s chat about that one time when my Predator 3500 generator decided it wanted to work up a sweat, literally! Yup, it got way too hot, aka overheated. But guess what? I tackled it, and you can too!

Dirty Muffler? Say No More!

After some detective work, I realized my generator’s muffler was the main troublemaker. It was all grimy inside! And here’s the fix: clean that muffler nestled by the spark plug. Grab yourself a small metal brush – they’re cheap and super handy. You can find them at any hardware store. A good scrubbing should do the trick. Oh, and don’t forget to also give the spark arrestor a deep clean. Trust me, it’ll thank you for it!

6. Running Weak or Dying on Run

Sometimes, our generator can act like it’s had a long day, running weak or even giving up mid-way. If that’s happening, don’t worry! I’ve got some tips to perk it right up.

Carburetor Troubles:

The carburetor is like the lungs of your generator. If it’s clogged up with dirt, your generator will struggle. Give it a good look, and if it’s super dirty, consider treating your generator to a brand-new carburetor carb assy. It’s like giving it a fresh breath of air!

That Pesky Spark Arrestor:

If your carburetor is looking all clean and shiny, then turn your attention to the spark arrestor. This little guy can sometimes get dirty or even break. If it’s just dirty, give it a clean. But if it’s broken? Well, you’ll need a new one. Good news – they’re pretty affordable, costing just around $3 to $5.


Let’s take a moment to appreciate the beauty of the Predator 3500 generator. Despite its occasional hiccups, this gem stands out from the rest. Why, you ask? Because it’s so darn quiet! Having tried a bunch of RV generators before, I can vouch for the fact that this one is like a silent ninja among the chattering ones.

Using this generator feels almost fancy. It’s like you’re experiencing a touch of luxury every time you power up your RV. So yeah, it might have its off days, but think twice before ditching it. Many of its issues are pretty fixable, either with a bit of DIY magic or with the help of a technician.

One last thing before we wrap up – always prioritize safety! If you spot something off with your generator, don’t just shrug it off. Ignoring problems, especially with crucial components like generators, can lead to bigger issues or even hazards. So, my friend, always stay vigilant and ensure you tackle any issues head-on.

In the grand scheme of things, the Predator 3500 is a keeper. With its quiet operation and the solutions we’ve discussed, you’re set for many comfy, powered-up RV adventures. Safe travels and happy camping!
