Generators are devices that convert mechanical energy into electrical energy. They are widely used in homes, businesses, and RVs because they provide reliable power even during blackouts.

A generator is a machine that converts mechanical energy into electrical energy to power your home.

In this article, we will be discussing how to get your generator to start, and why it may not be working.

Do Motorhomes Use A Generator?

Motorhomes use a generator to supply power to their appliances and lights. These generators are usually powered by either gasoline or diesel fuel.

Some models come with batteries that store enough energy to keep the motorhome running for up to eight hours. Others use propane tanks to store extra energy. In some cases, the generator is used only to charge the batteries.

Generators For RV Campers

The most popular type of generator for RVs is the portable generator. Portable generators are small and easy to transport. Many people choose them because they are compact and lightweight.

Portable generators are perfect for camping trips, boating, fishing, hunting, hiking, and picnics.

Portable generators are available in three different sizes:

  • Small – 6 HP
  • Medium – 10 HP
  • Large – 15 HP

A generator with a smaller capacity is better suited for campers who plan to stay in one place for long periods of time. It will provide enough power to run basic appliances like refrigerators, freezers, and air conditioners.

Larger generators are ideal for campers who plan on traveling frequently. They will allow campers to enjoy many activities without worrying about having enough power to run their appliances.

What Is The Best Generator Size For My RV?

When selecting a generator for your RV, consider its size and weight.

The best generator for your needs will depend on where you plan to park your RV and what kind of equipment you intend to use while camping.

Smaller generators are good for campers who plan only to spend a few days away from home.

They are light and easy to carry around. However, they may not be able to handle heavy loads such as large fridges, washing machines, and dishwashers.

Medium-sized generators are good for campgrounds and recreational areas where campers need to run multiple appliances at once. They are heavier than small generators and require more space to set up.

Large generators are great for campers who plan frequent trips. They are powerful enough to run larger appliances such as refrigerators, washer/dryers, and dishwashers without breaking down.

Turning The Generator On

When starting the generator, follow these steps:

Step 1

Open the door that connects the engine compartment to the passenger area.

Step 2

Locate the fuse box. This is usually located under the dash in front of the driver’s seat.

Step 3

Find the main fuse. This fuse is normally labeled “GENERATOR” or “GENERATOR FUSE”.

Step 4

Pull the fuse out of its socket.

Step 5

Replace the fuse.

Step 6

Close the door.

Step 7

Turn the ignition key to the ON position.

Step 8

Wait until the generator starts.

How To Keep Your Generator Working?

Before starting any project, make sure to perform routine maintenance on your generator to ensure maximum performance.

How To Start A Generator

Follow these tips to keep your generator running smoothly:

Clean Your Engine Oil

Oil filters should be changed every 3 months or when oil changes occur. If you don’t change the filter regularly, the engine could become clogged with dirt and debris.

Check Battery Levels

Make sure your batteries are fully charged. You can check the battery level by looking at the color of the terminals. When the terminal is dark green, the battery is full.

If the terminal is lighter green, the battery needs charging.

Change Air Filter

Air filters should be replaced every 30,000 miles. Replace them early because they tend to get dirty quickly. Dirty filters cause poor fuel economy and increase emissions.

Replace Spark Plugs

Spark plugs should be replaced after 20,000 miles. Replacing spark plugs helps prevent damage to your engine.

Check Exhaust System

Exhaust systems should be inspected annually. Check for cracks, corrosion, and loose connections.

Tighten any loose bolts and replace worn gaskets.

Keep It Clean

Use only approved lubricants and cleaners to clean your generator. Never use gasoline or other petroleum products.

Never Leave Generators Running While Unattended

Always turn off your generator when leaving it unattended. Leaving a generator running while unattended increases the risk of fire and explosion.

Avoid Improper Installation

Install your generator according to manufacturer instructions. Failure to do so may result in serious injury or death. Do not install generators near combustible materials such as wood, paper, or plastic.

Generator Troubleshooting Guide

This guide will help you troubleshoot problems with your generator.

Follow each step carefully to determine which component needs repair or replacement.

  • Make sure the generator has enough oil. Oil level should be at least halfway full.
  • Check the windings of the alternator. They should look shiny and smooth.
  • Check the belt tension. Tension should be set correctly for the size of the generator. Too much tension can damage the belt.
  • Check the voltage output of the battery. Voltage should be about 14.4 volts DC.
  • Check the charging circuit. If there are no signs of electrical current flowing through the wires, then check the wiring harness.
  • Check the starter motor. If the starter does not start the generator, then check the cables connecting the starter to the generator.
  • Check the power switch. If the switch does not work, disconnect the power cord from the outlet and try again.
  • Check the ground connection. If there is no continuity between the ground wire and the frame of the generator, then check if the grounding strap is connected.
  • The air filter may need to be cleaned or replaced. You check on the housing side of the generator.


The generator is an important part of your RV. It provides power for lights, appliances, refrigeration, and more. However, it is critical to keep it in good condition, so you don’t need to spend hours repairing it.

We hope you have liked this guide and now understand how to turn your generator on. Thanks for reading!
