Fuel Shutoff Solenoid for Bobcat 753 763 S185 / Kubota V2203 V2003 V1505 - 12V 3-Wire - Replaces 6681513 / 1C010-60015

Fuel Shutoff Solenoid for Kubota V2203 Engines — Replaces Bobcat 6681513 / Kubota 1C010-60015

Fix your "crank no start" condition. This is the direct replacement fuel stop solenoid for the Kubota V2203 diesel engine — the most common engine in Bobcat skid steers, Kubota tractors, Carrier reefer units, and Genie/JLG lifts. 12V, 3-wire design with rubber boot. Replaces Bobcat 6681513 / 6667992 and Kubota 1C010-60015 / 1G925-60011 / 1A021-60017.

The Problem

Your engine cranks but won't start — or it starts only if you manually hold the fuel lever open. This is the classic symptom of a failed fuel shutoff solenoid. Here's what happens: inside this solenoid is a "pull" coil that yanks the fuel lever open when you turn the key. When the pull coil burns out (which it will — it handles massive inrush current every time you start the engine), the lever stays in the "off" position and the engine gets no fuel.

You might be able to start the engine by manually pulling the lever or jamming a zip-tie to hold it open — but that's a temporary fix and a safety hazard (the engine won't shut off when you turn the key, because the solenoid can't push the fuel lever back to "off").

The Solution

Direct replacement 12V fuel shutoff solenoid with heavy-duty pull and hold coils. Designed for the high-heat environment of the engine bay. Silver cylinder body with black rubber boot and 3-wire connector — drops directly onto the Kubota V2203 injection pump. No modifications, no adapters.

⚠️ CRITICAL: 3-Wire Configuration

This solenoid has 3 wires with specific jobs. Connecting them incorrectly will burn out the solenoid immediately.

• Red Wire — HOLD (Low Amp): Keeps the fuel lever open during operation. Low continuous current.
• White Wire — PULL (High Amp): Provides the high-current "yank" to open the fuel lever during cranking. Only energized for a few seconds during startup.
• Black Wire — GROUND: Chassis ground.

⚠️ If the PULL wire stays energized after the engine starts (due to a wiring fault or stuck relay), the pull coil will overheat and burn out within minutes. This is the #1 reason people burn through solenoids. If your new solenoid fails quickly, check for a wiring issue — the pull circuit should de-energize once the engine is running and the hold circuit takes over.

• Visual ID: Silver cylinder body (approx 2.5" long) with a black rubber boot on the back end and a 3-wire connector
• The Quick Test: Turn the key to "ON" (don't crank) — you should hear the solenoid click/thunk as it pulls the fuel lever open. No click = dead solenoid

⚠️ The Kubota V2203 engine is used in hundreds of different machines. If your machine has a V2203 and the solenoid matches the physical description above (silver body, rubber boot, 3-wire), this is most likely the correct part. Contact us with your model and serial number if you're unsure.

Why Buy From Trenchwell?

• Fixes the #1 "Crank No Start" Problem: This solenoid is the most common cause of a Kubota V2203 that cranks but won't fire. If someone zip-tied your fuel lever open — this is the part you need.
• Save $70–$150: Bobcat dealers charge $160–$240 for this solenoid. We offer the identical OEM-spec unit at $89. Same design, same 3-wire configuration, massive savings.
• In Stock, Ships Fast: The V2203 is the most popular diesel engine in the compact equipment market. We stock this deep because we know you need it yesterday.
• 3-Wire Wiring Guide Included: We tell you exactly which wire does what (Red = Hold, White = Pull, Black = Ground). This is the information that prevents you from burning out the new solenoid in 5 minutes.
• Heavy-Duty Design: Rated for the high-heat engine bay environment. Continuous-duty hold coil. The pull coil is designed to handle the massive inrush current of engine startup.

Installation Notes

• Shut off the engine and disconnect the battery (safety first)
• PHOTOGRAPH the existing wiring before disconnecting anything — the 3 wires must go back exactly as they were
• Disconnect the 3-pin electrical connector from the old solenoid
• Remove the mounting hardware (usually 1–2 bolts) securing the solenoid to the injection pump
• Pull the old solenoid straight out — note the plunger orientation
• Compare old and new solenoids side by side — verify body length, plunger, and connector match
• Install the new solenoid onto the injection pump
• Reconnect the 3-pin connector — verify correct wire alignment (Red=Hold, White=Pull, Black=Ground)
• Reconnect the battery
• Turn the key to ON (don't crank) — listen for the solenoid "click" as it pulls the fuel lever
• Start the engine — it should fire normally
• Turn the key OFF — the engine should shut down immediately (the solenoid releases the fuel lever)
• If the engine doesn't shut down when you turn the key off, the pull circuit is staying energized — check wiring and relay

Frequently Asked Questions

My engine starts if I manually hold the fuel lever — is this the solenoid?
Yes. That's the classic symptom. The pull coil inside the solenoid has burned out, so it can't pull the fuel lever open electrically. Manually holding the lever proves the engine is fine — the fuel system just can't open the lever on its own. Replace the solenoid.

I replaced the solenoid and it burned out again within a week — why?
The "pull" wire (white) is staying energized after the engine starts. The pull coil is only designed for a few seconds of high-current draw during cranking. If a wiring fault, stuck relay, or faulty ignition switch keeps the pull circuit live while the engine runs, the coil overheats and burns out. Check the pull circuit relay and the ignition switch wiring.

Is this the same solenoid for the fuel shutoff AND the traction lock?
No. The fuel shutoff solenoid (this listing — 6681513) mounts on the injection pump and controls fuel flow. The traction lock solenoid (6681512) is a separate part that controls the parking brake. They look similar but are not interchangeable. Make sure you're ordering the correct one.

Will this fit a Carrier reefer unit?
If your Carrier Transicold reefer uses a Kubota V2203 engine and the existing solenoid matches the physical description (silver body, rubber boot, 3-wire, mounted on the injection pump), then yes. Verify the Kubota part number (1C010-60015 or similar) in your Carrier service manual.

What does each wire do?
Red = HOLD (low amps, keeps the lever open while the engine runs). White = PULL (high amps, yanks the lever open during cranking — only stays on for a few seconds). Black = GROUND (chassis ground). If you swap Red and White, the pull coil will stay energized and burn out.
