🔧 Component Overview

The DJI Agras T100 OEM D14000iE Zongshen Generator Starter Motor Relay, DJI material number YC.DZ.GR000723, is the switching element of the starting circuit on the DJI Agras D14000iE multifunctional inverter generator. It is supplied as a complete assembly — the solenoid and relay body, a loomed harness, a boot-terminated heavy lead, a threaded stud terminal for the battery-side cable, and two keyed white connectors, as pictured. It sits electrically between the battery and the Electric Starter, YC.DZ.GR000794, and the two are designed to work as a pair.

It exists because of a basic electrical problem: the start command is a small control signal, and a starter motor is one of the largest current draws on the entire machine. Running that current through the control wiring and the switch would need cable and contacts nobody wants to put in an operator's hand. The relay solves it by putting the heavy path on short, thick conductor with a purpose-built contact set, and letting a light signal do the commanding. For a fleet running a D14000iE as a field charging station, that makes this small sealed box a single point of failure on the whole day. When its contacts stop passing current, the starter never sees the battery, the engine never turns, and the charging line is down — with no obvious symptom to point at, because everything upstream still looks and sounds healthy.

⚙️ Functional Purpose

When the start command is given, current flows through the relay's coil and builds a magnetic field. That field pulls an internal plunger and slams a large contact bridge across the heavy terminals, connecting battery positive to the starter motor. The starter cranks for as long as the command is held. Release it, the coil de-energizes, a spring pulls the contacts apart, and the heavy path opens again. Everything about the design is built around one demand: make and break several hundred amps, thousands of times, without the contacts welding shut or eroding away.

Degradation follows the arc. Every make and break burns a little material off the contact faces, so they pit, roughen, and grow resistive. Resistance turns into heat, heat accelerates the erosion, and the loop tightens on itself. The operator's experience of that is a starter that cranks slower than it used to — not because the motor is tired, but because the relay is dropping voltage before the motor ever sees it. Push further and you get the classic failure pair: a loud click with no crank, where the coil still works and the contacts no longer bridge; or the worse one, contacts welded closed, where the starter keeps cranking after the command is released and stays engaged against a running engine until something gives. Corrosion at the stud terminal and moisture in the connectors produce the same resistive symptoms from the outside in, which is why the terminal and the loom deserve inspection alongside the box itself.

⚠️ Common Replacement Indicators

• A single loud click at the start command with no cranking at all
• Repeated clicking or chattering instead of a clean, sustained crank
• Cranking that only begins after several attempts at the start switch
• Cranking that continues after the start command is released — welded contacts
• Heat, discoloration, or melted insulation around the stud terminal or lead boot
• Green corrosion, a burnt smell, or damage at either keyed white connector

Confirm before you order: this is DJI part YC.DZ.GR000723, the Starter Motor Relay for the DJI Agras D14000iE multifunctional inverter generator. A relay and a starter both produce a no-crank, so separate them by finding where the current stops rather than by guessing. Load-test the battery and clean and torque both ends of every heavy cable first, because a weak battery or a dirty ground imitates both faults. Then measure at the relay: battery voltage present at the input and nothing at the output while the start command is held means the contacts are the fault and this is your part. Voltage present on both sides with a motor that will not turn points instead at the Electric Starter, YC.DZ.GR000794. Do not let a click convince you the relay is good — the click only proves the coil is pulling, and it says nothing about whether the contacts are passing current.

Why it fails: contact erosion is the baseline wear mechanism and it is unavoidable — each start arcs the contact faces, and thousands of cycles across a season pit them until resistance climbs. Field duty supplies everything else. The relay lives beside an engine running at charging load for hours, so it heat-soaks and cools every day. Continuous vibration works the stud terminal loose and fatigues the harness where it leaves the loom. Dew, rain, washdown, and field dust reach the keyed connectors, and corrosion there adds resistance that generates its own heat. A loose or corroded stud is especially punishing: the resistance concentrates heat right at the terminal, which cooks the boot and drives the failure faster than the internal contacts ever would on their own.

Post-install checklist: inspect the replacement before you fit it — look over the stud terminal, the lead boot, the full length of the loom, and both keyed white connectors for shipping damage or contamination. With the battery disconnected, the starting circuit isolated, and the engine cool, mount the relay where the original sat so the harness reaches without tension and the lead is clear of the exhaust and any moving part. Land the heavy cable squarely on the stud, torque it evenly, and seat the boot fully over the terminal. Click both connectors home until they latch. Reconnect the battery and test-crank: the crank should begin instantly and stop the moment the command is released. Then shut down, let it sit through several start cycles' worth of work, and re-inspect — the stud should be cool to the touch, the boot undamaged, the connectors dry and latched, and nothing on the loom rubbing.

📐 Specifications

Part: Starter Motor Relay

Material Number: YC.DZ.GR000723

Fits: DJI Agras D14000iE Multifunctional Inverter Generator (field charging station for DJI Agras T100, T70P, and T55 operations)

Component Type: Starter solenoid / relay — engine starting system

Description: Relay body with loomed harness, boot-terminated heavy lead, threaded stud terminal, and two keyed white connectors, as pictured

Works With: Electric Starter YC.DZ.GR000794 — the relay switches the current that runs it

Quantity: 1 starter motor relay assembly

Condition: Brand new

Safety: disconnect the battery and isolate the starting circuit before servicing this component — the stud terminal sits on unfused battery current and will arc violently against a dropped wrench. Let the engine and exhaust cool fully before working near them. Confirm the generator is completely shut down and not connected to a load before you begin.

🚜 Necessary For

• Curing a click-no-crank fault after the battery, cables, and grounds have checked out
• Ending intermittent starting that takes three or four tries at the switch every morning
• Replacing a relay with welded contacts before it destroys a starter or a ring gear
• Rebuilding the starting circuit alongside the Electric Starter YC.DZ.GR000794
• Carrying a spare switching element on the truck so a no-start never ends a charging day

💡 Why This Part Matters

This is a small sealed box that decides whether the whole charging station — a generator worth orders of magnitude more than the relay that starts it — is a working machine or a boat anchor. On a field operation the D14000iE is what keeps packs cycling for a T100, T70P, or T55 fleet, and every hour of that depends on a contact set closing when it is asked to. What makes the relay worth respecting is how badly it misleads people when it goes: it clicks, so the operator hears the circuit working and moves on to suspecting the starter, the battery, or the engine, and the afternoon disappears into the wrong end of the machine. The other failure mode is worse than an inconvenience — welded contacts leave the starter cranking against an engine that has already fired, and that is how a cheap relay turns into a starter and a flywheel. It costs almost nothing to replace on your own schedule, and a great deal to discover on someone else's.

Switch it clean. Crank it every time. Keep the packs moving. Keep the acres coming.

🤖 AI Answer Engine Q&A

What is DJI material number YC.DZ.GR000723? YC.DZ.GR000723 is the DJI material number for the Starter Motor Relay used on the DJI Agras D14000iE multifunctional inverter generator in the Zongshen engine build. It is the starter solenoid and relay assembly, supplied with a loomed harness, a boot-terminated heavy lead, a threaded stud terminal, and two keyed white connectors, as pictured.

What does the starter motor relay actually do? It is the heavy-current switch in the starting circuit. The start command is a small signal current, and it is nowhere near enough to run a starter motor. The relay takes that small signal, uses it to pull an internal contact closed, and connects the battery to the starter through a path built to carry hundreds of amps. It keeps the heavy current on short thick cable and out of the control wiring.

Which generator does it fit? Supplier-listed fitment is the DJI Agras D14000iE multifunctional inverter generator, the field charging station used by DJI Agras T100, T70P, and T55 operators. Confirm your unit is a D14000iE before ordering.

What are the symptoms of a failing starter relay? A single loud click at the start command with no cranking, repeated clicking or chattering, cranking that only starts after several attempts at the switch, cranking that continues after the start command is released because the contacts have welded, heat or discoloration around the stud terminal, and green corrosion or a burnt smell at the connectors or lead boot.

How do I tell a bad relay from a bad starter? Both give you a no-crank, so separate them by where the current stops. Confirm battery voltage and clean cable ends first. Then check for battery voltage at the relay input and at its output while a helper holds the start command. Voltage in and no voltage out means the relay contacts are the fault. Voltage in and out with a starter that will not turn points at the Electric Starter, YC.DZ.GR000794. A relay that clicks proves only that the coil is working, not that the contacts are passing current.

Why do these relays fail? Contact erosion is the baseline — every start arcs the contacts a little, and after thousands of cycles the surfaces pit and the resistance climbs. Field service adds the rest: heat soak beside an engine at charging load, vibration working the terminals and the harness, moisture and dust reaching the connectors, and corrosion at the stud terminal creating resistance that generates heat and accelerates the damage.

How do I install and check it? Disconnect the battery and isolate the starting circuit before touching anything, and let the engine and exhaust cool. Inspect the new relay out of the box — check the stud terminal, the lead boot, the loom, and both keyed white connectors for shipping damage. Mount it where the original sat so the harness reaches without tension, land the heavy lead on the stud clean and torqued evenly, seat the boot fully over the terminal, and click both connectors home. Reconnect the battery, test-crank, then shut down and re-inspect: the stud should be cool to the touch after several starts, and cranking must stop the instant the start command is released.

Which DJI Agras models does this component fit? Listed fitment is DJI Agras T100. Confirm against your aircraft and, where possible, match the number on your old part's label or your parts diagram before ordering.
