The fuel solenoid 280077-1224-e1 is compatible with several Walbro carburetors, including the 28AH76, 28AH77, 28BH76, 28BH77, 28CH77, 31A507, and 31A607. It is also compatible with various models of lawnmowers, including the John Deere E100 and TroyBilt. The solenoid is easy to install, but it is recommended that it be done by a professional.

How to remove the fuel solenoid

To remove the fuel solenoid from your Briggs and Stratton 24hp twin v, you will need to gather some tools. These include a wrench, preferably a 1/2-inch thin wrench, and a hammer. You may also need a multimeter to check the current at the solenoid.

Start by disconnecting the fuel solenoid's electrical wiring. Then, use the wrench to try and loosen the solenoid; it loosens counterclockwise. If the solenoid is too tight, carefully tap the wrench with the hammer to help loosen it.

If the solenoid is still not budging, it may be heavily corroded. In this case, you will need to remove the carburetor from the engine to access the solenoid from the inside.

Once the solenoid is removed, you can clean it or replace it with a new one. Ensure that any new parts are compatible with your engine model.

How to check the solenoid's electrical connection

To check the electrical connection of a solenoid, you will need to perform a series of tests. Before beginning, ensure you are wearing protective equipment, such as insulated gloves and eyewear, to protect against shock hazards from the live voltage supplied to the solenoid during diagnosis.

Firstly, disconnect the solenoid from any electrical connections or wiring attached to it. Then, refer to the solenoid manufacturer's specifications to determine its supply voltage (AC/DC).

Using a Multimeter

One way to test the solenoid is by using a multimeter. Set the multimeter's dial to measure resistance, denoted by the Ω symbol. The solenoid typically has three terminals: one is usually a peculiar-looking ground connection, while the other two look alike and are to be tested. If you are unsure, check the manufacturer's manual to determine the terminals correctly.

To test the solenoid, connect the multimeter probes to the terminals, ensuring that the connections are properly in contact. The resistance reading can vary depending on the specific solenoid valve, so consult the manufacturer's documentation to determine the expected resistance value range.

If you get an 'OL' reading (infinite resistance) on the multimeter, this signifies an incomplete circuit within the solenoid, possibly due to a bad coil or wire, and the solenoid will need to be replaced.

You can also use the multimeter to perform a voltage test to ensure the solenoid receives or works with the correct amount of voltage supplied by a power source. First, check the solenoid manual to see if the device works on AC or DC voltage. Rotate the multimeter dial and set it to measure AC (V~) or DC (V...) voltage.

Connect the multimeter probes to the solenoid terminals and note the results. If the solenoid is operating normally, the multimeter should read a voltage that matches the rated voltage of the valve; otherwise, the coil is faulty and needs to be replaced.

Without a Multimeter

If you don't have a multimeter, you can test the solenoid using a battery. Ensure the battery is fully charged and matches the voltage rating of the solenoid. For example, a 12V solenoid will use a 12V battery.

Connect the battery to the solenoid using insulated jumper wires with alligator clips. Connect the positive terminal of the battery to one of the solenoid's coil terminals and the negative terminal of the battery to the other coil terminal.

When the battery is connected, the solenoid should activate, emitting an audible clicking sound. No audible clicking typically indicates a faulty solenoid. Once finished, disconnect the jumper wires from the battery and the solenoid.

Click Test

Another simple way to test a solenoid is by listening for a clicking sound, which indicates that the solenoid is engaging and attempting to send power to the starter motor.

First, ensure safety by turning off the power to the solenoid's circuit and put on safety goggles and gloves. Locate the solenoid, and visually inspect it for signs of damage, corrosion, or loose connections. The wiring to the solenoid should be intact and securely connected.

Before activating the power, ensure the power source (battery or power supply) matches the solenoid's voltage rating. Activate the power source or the switch that controls the solenoid. Listen for a clicking sound. If you hear a single loud click, it indicates the plunger is moving, and the solenoid is functioning correctly.

Rapid clicking can indicate an issue with the power supply (such as inefficient voltage) or a problem with the control switch. No audible click often indicates the solenoid is not receiving power or has an internal issue like a broken coil or mechanical blockage.

How to replace the solenoid with a bolt

To replace the solenoid with a bolt, follow these steps:

Firstly, identify the size of the bolt you need. In this case, the bolt size is 5/16x24, but you can also take the solenoid to a hardware store to find the correct bolt size using their thread finder.

Next, purchase a bolt that matches the size and thread pattern of the solenoid. You may also need to buy a gasket or use some Teflon tape to prevent leaks.

Now, remove the solenoid by unscrewing it. You may need to use a wrench to loosen it, and be careful not to damage the threads.

Once the solenoid is removed, screw in the bolt you purchased. Make sure it is tight and secure.

Finally, install an inline fuel shut-off valve in the fuel line. This will serve the same purpose as the solenoid, allowing you to control the flow of fuel. Remember to turn off the valve when the equipment is not in use.

You may also want to put a sticker on the key or equipment as a reminder to turn off the fuel valve when not in use.

How to test the solenoid with a 12V battery

To test a solenoid with a 12V battery, you will need a battery that matches the solenoid's voltage rating, insulated jumper wires with alligator clips, and protective safety gloves and goggles.

Step 1:

Ensure safety by turning off any power to the solenoid and disconnecting it from the circuit to avoid electrical hazards.

Step 2:

Locate the solenoid terminals. The solenoid coil typically has two main terminals.

Step 3:

Make sure the battery is fully charged and matches the voltage rating of the solenoid. For example, a 12V solenoid will use a 12V battery.

Step 4:

Connect the battery to the solenoid using the insulated jumper wires with alligator clips. Connect the positive terminal of the battery to one of the solenoid's coil terminals, and the negative terminal of the battery to the other coil terminal.

Step 5:

When the battery is connected, the solenoid should activate, emitting an audible clicking sound. No audible clicking typically indicates a faulty solenoid.

Step 6:

Once finished, disconnect the jumper wires from the battery and the solenoid.

Additional Notes:

• It is important to remember that car troubles may not be due to the solenoid. Test your car battery first to ensure it is not the root of the problem.
• If your solenoid is not working properly, check for corrosion or grease on the solenoid as this could be causing a loss of power.
• This process can be used to test all types of solenoids, including transmission shift solenoids, humidifier solenoids, and solenoid valves.
