Do you have a Kubota L3800 tractor that won’t start? Unsure of where the starter relay is located and how to test it on this machine?
In this article, we will explore the Kubota L3800 starter relay location and the tests necessary to identify it as the culprit of starting issues. Prepare to troubleshoot problem starting conditions in order to get your Kubota out and running again.
Read on to learn more about locating the starter relay on the Kubota L3800, how to test it, and what to do if it’s not the cause of your starting problems.
kubota starter relay location
The Kubota L3800 tractor starter relay is located behind the steering wheel, rear bonnet, and meter panel. Testing the starter relay involves applying battery voltage and measuring for zero ohms.
Lack of 12V on the starter terminal ST may indicate a problem with this relay. Other potential causes for starting issues include blown fuses, faulty switches, and problems with the Range Gear Shift Lever Switch.
Updating equipment from L3800 to L3800HST is also suggested.

Kubota Starter Relay Location
For the Kubota L3800 series tractors, the starter relay is located behind the steering wheel, rear bonnet, and meter panel. Testing the starter relay involves applying battery voltage and measuring for zero ohms.
If there is lack of 12V on the starter terminal ST, the cause may be a problem with the starter relay.
Testing The Starter Relay
To correctly test the starter relay, the steps are as listed below:
- Step 1: Remove the cover of the starter relay box and disconnect the relays from the battery.
- Step 2: Connect the black lead of a multi-meter to the negative battery post and the red lead of the multi-meter to the positive battery post.
- Step 3: Set the multi-meter to measure resistance of the starter relay box.
- Step 4: Reconnect the relay into the battery and turn the ignition switch on.
- Step 5: If the starter relay is working properly, the readings should be zero ohms.
If the readings are not zero ohms, then the starter relay may need to be replaced.
Reasons For Starting Issues
Other potential causes for starting issues, aside from the starter relay, include blown fuses, faulty switches, or problems with the Range Gear Shift Lever Switch. Updating equipment from the L3800 to the L3800HST is also suggested to ensure that all components are up to date.
Reasons For Not Starting
The most commonly reported cause for a Kubota tractor not starting is dead battery, typically due to corroded terminals, loose connections, or faulty safety switches. Other issues can include engine or fuel-related problems.
To further identify the issue and help narrow down the problem to one of these items, it is important to run a troubleshooting process.
When running a troubleshooting process, it is critical to take into account where and when the issue is occurring. Following the troubleshooting tips listed below should help to narrow down the source of the issue and allow you to fix it more quickly and effectively:
- Dead Battery: Testing the battery with a hydrometer and charging the battery are the fastest ways to see if the issue is related to the battery.
- Corroded Terminals: Cleaning the terminals and inspecting the wires for any sign of damage can help rule out corrosion.
- Loose Connections: Checking for tightness in the connections may help resolve the issue.
- Faulty Safety Switches: If the safety switches appear to be faulty, then they should be replaced as soon as possible.
- Engine/Fuel Related Issues: It is a good practice to always check the fuel levels and inspect the spark plugs and fuel lines for any signs of damage before attempting to start the tractor.
Checking For Battery Issues
When checking for battery related issues, it is important to first test the battery terminal voltage to confirm that the battery is at the correct level of charge. If the battery voltage is low, it is then important to check for corrosion on the terminals.
In some cases, the terminals may need to be removed and cleaned to ensure that the connection is good. It is also important to inspect the wires for any signs of damage as well.
After the terminals have been cleaned and the wires inspected, it is also a good practice to charge the battery to make sure that it is at full capacity.
Now you know the Kubota starter relay location and have a few troubleshooting tips to use when diagnosing your Kubota tractor not starting. Put your knowledge to action and get your tractor back up and running as quickly as possible.
