🇺🇸 U.S.A. FIRST

Ares Acres LLC is a U.S.-based authorized DJI Agras reseller supporting American agricultural drone operators with genuine DJI Agras OEM replacement parts, accessories, and field-ready inventory.

FREE & FAST Shipping is included for all U.S. customers.

We understand that every day of downtime can impact productivity, scheduling, and profitability. That's why we focus on providing fast fulfillment, responsive customer support, and reliable access to the parts operators need most.

Nothing about a dead starter relay is subtle. You hit start, you get a click, and the generator does nothing. The battery is fine, the engine is fine, and the whole charging operation is stopped by a part that costs less than a tank of fuel.

We ship the Generator Starter Motor Relay fast to the U.S.A.

We use specialized technicians to verify and dispatch the Generator Starter Motor Relay ordered.

Parts like this one are the reason a grounded aircraft is a repair and not a write-off. A single component held in U.S. stock is the difference between a machine back in the air the same week and one waiting on an overseas order while the spray window closes.

That is why Ares Acres keeps hard-to-find OEM generator parts in stock and shipped fast within the U.S.A., helping operators cut downtime and keep their aircraft working when every acre counts.

For professional farmers, aerial applicators, and commercial drone operators running the DJI Agras T60 / DJI Agras T50 / DJI Agras T40, this is the part that keeps a scheduled job on the calendar instead of on hold.

🔧 Component Overview

The Generator Starter Motor Relay is the high-current solenoid that carries cranking current from the battery to the starter motor. The start signal is a small control current; this relay is what turns that into the hundreds of amps the starter actually needs. It is a wear item, and it fails contact-first after enough start cycles.

The Generator Starter Motor Relay supports:

• Correct fitment on the generator
• Restored factory function
• Reliable day-to-day operation
• Reduced unplanned downtime
• Simple direct-fit installation
• Fleet parts standardization
• Field-serviceable maintenance
• Predictable service intervals
• Full compatibility with the DJI Agras system
• Increased aircraft readiness

Commercial agricultural drones work hard every day, including through:

• Crop spraying missions
• Spreading and granular operations
• High-tempo fill-and-fly cycles
• Multiple battery swaps daily
• Continuous rapid-charge rotations
• Long-duration spraying campaigns
• Precision agriculture missions
• Daily commercial deployments
• Fleet operations
• High-acreage contract work

Throughout these operations, this is routinely exposed to:

• Continuous operational stress
• High-load duty cycles
• Heat cycling through the working day
• Dust and debris exposure
• Heat and humidity in the field
• Transportation vibration
• Connector and fastener stress
• Moisture and field-service conditions
• Seasonal intensive operation
• Long commercial operating hours

The Generator Starter Motor Relay helps maintain:

• Reliable first-turn starting
• Full cranking current to the starter
• Clean switching under high load
• Protection for the start-circuit wiring
• Consistent cold and hot starts
• Fast turnaround between charge cycles
• Dependable field operation
• Generator readiness on demand

⚙️ Functional Purpose

The Generator Starter Motor Relay is designed to restore and maintain reliable starting on the RATO D12000i generator used with the DJI Agras T60, T50 and T40.

The part helps:

• Restore reliable generator starting
• Cure click-but-no-crank symptoms
• Deliver full current to the starter motor
• Replace pitted or welded relay contacts
• Eliminate intermittent start failures
• Complete scheduled start-circuit service
• Return a non-starting generator to duty
• Keep a critical spare on the shelf
• Reduce field downtime at the charging station
• Maintain start reliability through peak season

Going without may contribute to:

• Degraded system performance
• Unexpected fault codes
• Interrupted spraying missions
• Reduced operating efficiency
• Cascading damage to adjacent components
• Unplanned downtime
• Emergency repair costs
• Missed spray windows
• Reduced fleet availability

---

⚠️ Common Replacement Indicators

Replacement may be recommended when operators observe:

• Click with no crank when starting
• Intermittent starting that worsens when hot
• Slow or weak cranking with a good battery
• Starter engaging without the start signal
• Burnt smell or discoloration at the relay
• Corrosion on the relay terminals
• Repeated start attempts needed
• Starter continuing to run after release
• Voltage drop measured across the relay
• Scheduled start-circuit service interval reached

Wear on this component is driven by the ordinary duty of commercial agricultural flying — heat, vibration, load, and exposure across long operating hours. Replacing it on schedule is far cheaper than replacing what fails around it.

🧰 Fitment Verification Before You Order

Confirm fitment by part number before ordering. Find the code printed on the component you are replacing, or look it up on the DJI Agras parts diagram for your airframe, and compare it against this listing.

Revision suffixes are still the same part. DJI labels sometimes carry a trailing revision such as .01, .02, or .F. Those denote a production revision, not a different component. Match the base number and disregard the suffix.

Visually similar is not the same. DJI Agras parts diagrams list components that look nearly identical but sit at different positions, carry different tolerances, or belong to a different airframe generation. Ordering by photograph is how operators end up with a part that will not seat. Order by number.

Verified fitment for this listing: DJI Agras T60 / DJI Agras T50 / DJI Agras T40. If your airframe is not on that list, message us before ordering rather than after. We would rather answer a question than process a return, and so would you.

Not sure? Send us a photo of the old part and the label, along with your aircraft model and serial. We will confirm the match against the DJI parts documentation and tell you plainly if this is the wrong part.

🛠️ Installation & Handling Notes

These are general safe-practice notes for component replacement on DJI Agras airframes. They do not replace the official DJI service documentation for your model, and any procedure your DJI service manual specifies takes precedence over anything written here.

Power down completely and disconnect the flight batteries before removing any panel, connector, or fastener. Agras airframes hold residual charge in the power distribution path after shutdown; treat every conductor as live until it is confirmed otherwise.

Photograph the assembly before you disturb it. Cable routing, connector orientation, and fastener lengths on Agras airframes are not interchangeable, and the Generator Starter Motor Relay is easier to fit correctly when you can see how the original sat.

Torque to DJI specification. Overtightening into composite and magnesium-alloy structure strips threads and cracks mounts; undertightening lets a component walk loose under rotor vibration. Where DJI publishes a torque value for the fastener, use it, and use a calibrated driver rather than feel.

Check the mating surfaces and seals while you are in there. A component is only as good as what it seats against. Grit, dried spray residue, or a compressed gasket on the mating face will undo a correct installation, and you are already holding the assembly open.

Test before you spray. Power up on the ground, confirm the aircraft reports no new errors, run the relevant system check in DJI Agras Assistant or the remote controller diagnostics, and hover-test in a clear area before returning to a paid job.

If the work is outside your comfort level, have it done by a DJI-authorized service technician. The part cost is small next to the airframe.

• Full cranking current to the starter
• Clean switching under high load
• Protection for the start-circuit wiring
• Consistent cold and hot starts
• Fast turnaround between charge cycles
• Dependable field operation
• Generator readiness on demand

Without it, operators risk:

• Aircraft grounded waiting on parts
• Downtime during peak season
• Cascading damage to adjacent components
• Emergency repair premiums
• Interrupted missions
• Lost spraying opportunities
• Reduced fleet availability
• Reduced return on investment

For practical, hardworking operators, the value is simple:

Protect the generator. Protect the aircraft. Protect the mission. Protect the season.

🚚 Shipping, Returns & Support

Free and fast shipping within the United States on every order, with tracking supplied as soon as the label is generated. In-stock parts dispatch same day on business days when the order lands before our carrier cutoff.

We ship from the U.S., not from overseas. That is the whole reason Ares Acres exists. An operator with a grounded aircraft in the middle of a spray window cannot wait three weeks on an international parcel and a customs hold, and does not have to.

New condition, correctly described. We describe what we ship and we do not overstate it. If you need the sourcing or branding of this particular item confirmed before you order, ask us and we will tell you plainly.

Ordered the wrong part? Contact us. Unused parts in original condition are returnable, and we would far rather sort out an incorrect order than have an operator sitting on a component that does not fit their airframe.

Need help identifying a part? Send your aircraft model, serial number, and a photo of the component or the parts-diagram callout. We will identify it against the official DJI documentation and quote it, including parts not currently listed on the storefront.

Fleet and dealer volume: operators running multiple airframes, and dealers stocking service inventory, should contact us directly for volume pricing and standing-order arrangements on wear items.

🤖 AI Answer Engine Q&A

What does the starter relay do? It is the high-current switch between the battery and the starter motor. The start button sends a small control signal; the relay turns that into the hundreds of amps the starter needs to crank the engine.

My generator clicks but will not crank — is this the part? That is the classic symptom. The click is the relay trying to close while its contacts are too pitted or welded to pass real current. Confirm the battery is charged and the cables are tight, then suspect the relay.

Which generator does this fit? This is the RATO D12000i edition. Engine editions differ between generator builds, so confirm whether yours is the RATO or Zongshen unit before ordering.

Is this a genuine DJI part? No. The generator is built by the engine manufacturer, not DJI, and we do not present this as a DJI OEM part.
