Are you facing the frustrating Generac “STOPPED – ALARM ERROR CODE 1505” and wondering how to resolve it?
Many Generac users encounter error code 1505, but with the right guidance, resolving it is entirely possible.
In this blog, we will provide practical solutions to help you troubleshoot and fix the issue.
How To Fix Generac Error Code 1505?
To fix Generac error code 1505, you can attempt a restart, check the battery, and inspect the starter contactor relay. Additionally, you can check the starter motor, and check the ignition coils.
1. Attempt A Restart
Sometimes, a simple restart can clear transient issues that might cause error code 1505. Restarting the generator can reset the system and possibly resolve the error without further intervention.
- Turn off the generator completely.
- Wait for a couple of minutes to allow all electrical charges to dissipate.
- Turn the generator back on and check if the error code 1505 has been resolved.
2. Check The Battery
The battery is often the culprit when it comes to the Generac error code 1505, which indicates a loss of RPM sense.
A faulty, dead, or improperly connected battery can prevent the generator from starting, leading to this error.
Ensuring the battery is in good condition and properly connected can often resolve the issue.
- Inspect the battery for any signs of damage or corrosion.
- Check the battery terminals to ensure they are clean and tightly connected.
- Test the battery voltage with a multimeter to ensure it is adequately charged (typically around 12 volts for a fully charged battery).
- If the battery is dead or not holding a charge, replace it with a new one that matches the specifications required by your Generac generator.
3. Inspect The Starter Contactor Relay
A malfunctioning starter contactor relay can also trigger error code 1505 by failing to engage the starter motor properly.
Checking the relay ensures that the electrical connections required to start the generator are functioning as intended.
- Locate the starter contactor relay according to your Generac model’s manual.
- Ensure the relay is energizing when you attempt to start the generator.
- Use a multimeter to check for voltage at wire 16 at the starter when the generator is being started.
- If the relay is not functioning correctly or there is no voltage, it may need to be replaced.
4. Check The Starter Motor
The starter motor is essential for initiating the engine’s operation. If it’s malfunctioning, it could lead to error code 1505, as the generator might fail to achieve the necessary RPMs during startup.
- Locate the starter motor according to your Generac generator’s manual.
- Inspect the starter motor for any signs of wear, damage, or loose connections.
- If the starter motor does not engage or sounds sluggish, it may need repair or replacement.
5. Check The Ignition Coils
Ignition coils are crucial for providing the spark to ignite the fuel in the engine. Faulty ignition coils can prevent the engine from starting, which might result in error code 1505.
- Access the ignition coils as per your generator’s service manual.
- Test the ignition coils with a multimeter to ensure they are functioning correctly.
- Replace the ignition coils if they are not operating within the manufacturer’s specifications.
6. Check Utility Loss
Generac error code 1505 can also indicate a problem with utility loss, meaning the generator is not sensing power from the utility line.
- Confirm that your home or facility is receiving power from the utility company.
- Check the automatic transfer switch (ATS) to ensure its operating correctly and sensing the utility power as expected.
- If the utility power is present and the ATS is not transferring power correctly, professional servicing of the ATS may be required.
7. Contact Generac Support
