Champion 46561 Generator: Specs, RV Use, Maintenance & Modern Replacements

The Champion 46561 is a 4,000 starting watt, 3,500 running watt gasoline generator with wireless remote start and an RV outlet. Champion built it for campers and RV owners, and plenty of them are still running.

It is a 120-volt machine. That makes it simple, light for its output and easy to plug straight into a travel trailer. It also means there are a few things it cannot do, and it helps to know them before an outage.

This guide covers the official specs from Champion’s manual, what the generator can run, how the remote start works, the maintenance it needs and the current Champion models that replace it.

What Is the Champion 46561?

The 46561 is a mid-size open-frame portable generator. Its manual calls it a “4000 Peak Watts, 3500 Running Watts” generator with wireless remote electric start.

It was aimed squarely at RV owners, and three things show it.

• A dedicated 30-amp RV outlet, so a travel trailer plugs in without an adapter.
• Wireless remote start, which lets you fire it up from inside the RV.
• Wheels and handles in the box, because 125 pounds is too much to carry far.

It is also a common small home backup unit. With 3,500 running watts it will keep a refrigerator, a furnace fan, lights and electronics going.

Champion 46561 Specs

The Outlets

Notice that both 30-amp outlets can deliver the generator’s full 3,500 watts. The duplex outlet is limited to 2,400 watts, so do not hang everything on it.

The panel also carries an Intelligauge meter for running hours, voltage and frequency, a battery switch, an ignition switch and push-to-reset breakers.

What Can the Champion 46561 Run?

Work from the two key numbers: 3,500 watts running and 4,000 watts for starting. Champion’s own wattage chart gives typical figures for the things people plug in.

Three practical lessons come out of that table.

• A 13,500 BTU RV air conditioner fits. Its starting surge of up to 3,500 watts is inside the generator’s 4,000-watt limit, as long as little else is running at that moment.
• A 15,000 BTU air conditioner is borderline. It can need up to 4,500 watts to start, which is more than the 46561 can give.
• Start the air conditioner first. Let it settle, then switch on the microwave or the coffee maker. Never start two motors at once.

For a home, the 46561 handles a refrigerator, a furnace fan, a sump pump, lights and chargers together. Add up your own loads with our Generator Size Calculator.

How the Wireless Remote Start Works

The remote is this generator’s party trick. The manual explains exactly how it behaves.

• It works within 80 feet.
• Two switches must be on. The remote only functions when both the battery switch and the ignition switch are in the ON position.
• The choke is automatic. There is no manual choke lever to set.
• It tries up to six times. Press START once and let the system work.
• Power is delayed by about 15 seconds. This lets the engine reach full speed before any load is connected.

If the battery does go flat, the 46561 still starts with the pull cord. A small maintainer such as the Battery Tender Junior keeps it charged in storage.

Starting and Stopping

1. Set the generator on level ground outdoors, at least 20 feet from the RV or house if you can.
2. Unplug or switch off all loads.
3. Turn the fuel valve on.
4. Press the battery switch and the ignition switch to ON.
5. Press START on the remote once, or use the start switch on the panel.
6. Wait for the 15-second delay, let the engine warm up, then connect your largest load first.

To stop, disconnect the loads and let the engine run for a few minutes. Turn the fuel valve off and let the engine run until it stops. Then switch off the ignition and the battery switch.

Fuel and Oil

• Fuel: regular unleaded gasoline, 85 octane or higher, with less than 10% ethanol. Do not mix oil with it.
• Tank: 4 gallons.
• Oil: 10W-30 4-cycle oil. The crankcase holds just 0.63 quart, which is a little over half a quart.
• Check it often. With so little oil on board, a small leak or a little burning makes a big difference. A low-oil sensor will stop the engine if the level falls too far.

Champion 46561 Maintenance Schedule

Valve clearance, if you check it yourself, is 0.005 to 0.007 inch on the intake and 0.007 to 0.009 inch on the exhaust.

The spark arrester matters to campers. Many public lands require one, and a clogged screen robs the engine of power. Cleaning it takes two screws and a wire brush.

Common Problems and Fixes

Champion’s troubleshooting chart for the 46561 is short. Here it is in plain English, with the remote start checks added.

If the engine surges or a breaker fault will not clear, the manual points to the governor, the brushes or the voltage regulator. Those are jobs for a service center.

A generator that sat all winter with fuel in it usually needs the carburetor drained or cleaned. Our guide to a generator that won’t start sets out the checks in order.

Parts and Storage

Keep these on the shelf and most problems are a ten-minute fix.

• Spark plug: NGK BPR6ES or an equivalent.
• Oil: a quart of 10W-30 covers a change with some to spare.
• Fuel stabilizer: STA-BIL Storage for fuel that will sit.
• Air filter: check it each season and replace it when it will not come clean.
• Fuel line: due every 3 years.

For storage, the manual’s steps are familiar. Add stabilizer and run the engine briefly. Turn the fuel valve off and let the engine run dry. Let it cool, clean it and change the oil. Remove the spark plug, add about half an ounce of oil to the cylinder, turn the engine over and refit the plug. Then store it clean and dry, with the battery switch off.

Our guide on how to store a generator covers the details, and how long gasoline lasts explains why fuel is the usual culprit.

Safety at the Campsite and at Home

The 46561 was built before carbon monoxide sensors became standard on portable generators. Its manual does not describe one.

At home, use heavy outdoor extension cords to individual appliances. If you want to feed your panel, remember that this is a 120-volt generator. Ask an electrician what your panel and transfer equipment can accept. Our guide to connecting a generator to your house explains the choices, and the generator safety tips cover the rest.

Modern Replacements for the Champion 46561

Champion still makes generators in exactly this size class. The current ones add a carbon monoxide shutoff, a longer warranty and, on some models, a second fuel.

Choosing between the last two types? Our guide to inverter vs conventional generators explains the trade-offs, and dual-fuel generators covers propane.

Keep It or Replace It?

A 46561 that starts well is worth keeping. It is a simple machine, and Champion still publishes the manual and parts diagrams.

Replace it when one of these is true.

• You want a carbon monoxide shutoff. This matters most at campsites, where generators run close to where people sleep.
• You want to run on propane. Your RV already carries it.
• You need quiet. An inverter is far kinder to the campsite.
• It needs an engine or alternator. Major repairs rarely make sense on a generator of this age.

The original warranty was a 2-year limited one: one year for parts and labor, and two years for parts. It has long since expired.

Common Mistakes With the Champion 46561 (and the Fix)

Pro Tips for Champion 46561 Owners

• Run it for 20 minutes every couple of weeks in the off season.
• Carry a spare plug and half a quart of oil in the RV.
• Use a proper 30-amp RV cord and keep it fully uncoiled so it does not overheat.
• Turn the air conditioner off before you stop the generator, and before you start it.
• Test the remote before a trip. Replace the fob battery if the range has dropped.
• Level the generator. The low-oil sensor can stop the engine on a slope even when the oil is full.
• Watch the Intelligauge. Falling voltage under load is an early sign that you are asking too much.

Real-Life Scenarios: What Should You Do?

These are typical situations that owners describe in forums and reviews. They are examples to help you decide, not quotes from real people.
