1502ES-12C7U1B2S1 Voltage-Specific Diesel Shutdown Solenoid

1502ES-12C7U1B2S1 is a configuration-specific fuel shutdown solenoid for Woodward 1500-1004 diesel control systems. The long code is functional data, not an optional catalog label: voltage, mounting, plunger, grounding, terminals, boot and spring family can change with individual suffix characters. The full removed-part code should remain intact on the inquiry, purchase order and carton label.

How to Read and Match the 1502ES-12C7U1B2S1 Configuration

1502ES-12C7U1B2S1 indicates C-series base mounting, internal M6 plunger thread, ungrounded electrical configuration, bellows boot family. Verify every suffix character on the removed unit.

Matching Point

Buyer Review

Complete code

1502ES-12C7U1B2S1 indicates C-series base mounting, internal M6 plunger thread, ungrounded electrical configuration, bellows boot family. Verify every suffix character on the removed unit.

Voltage

12V and 24V versions; select by complete OE and old-unit marking

Mounting

Compare flange/base style, hole centers and installed body angle.

Plunger

Match thread, resting length, travel direction and connection hardware.

Terminals and ground

Confirm terminal count and grounding method from service data; never rely on wire color alone.


Electrical and Mechanical Checks for 1502ES-12C7U1B2S1

A correct voltage alone does not prove interchangeability. Terminal arrangement, grounding method, plunger thread, boot clearance and return spring can change across nearby Woodward or Syncro-Start codes, while pull/hold faults can produce the same start-then-stop symptom as a failed solenoid.

Observed Situation

Recommended Check

Starts then stops

Check hold voltage after cranking and inspect pull/hold terminal assignment.

Will not shut down

Confirm the plunger reaches the fuel lever's complete stop position.

Coil overheats

Check incorrect voltage, restricted stroke and pull-winding timing.

Boot contacts bracket

Compare body angle, boot family and available clearance.

Code is partly unreadable

Use close label photos plus measured mount, thread and terminals before approval.


1502ES-12C7U1B2S1 Replacement Approval Checklist

Release the order only after electrical, mechanical and application evidence agrees with the removed assembly. The checklist below keeps fleet, distributor and service-team information on one approval record.

1502ES-12C7U1B2S1 Fuel Shutoff Solenoid FAQ

How should the 12V and 24V 1502ES-12C7U1B2S1 versions be separated?

Keep the complete voltage-specific reference and old-unit marking on the order. The 12V and 24V bodies may share mounting geometry, but their coils are not interchangeable. Confirm machine charging-system voltage at the old connector and label cartons by both OE and voltage to prevent mixed inventory.


Why must the complete 1502ES-12C7U1B2S1 suffix be retained?

Suffix characters identify mechanical and electrical features such as mounting, plunger thread, grounding, terminals, boot and spring family. Shortening the code can merge non-interchangeable versions in purchasing records. Photograph every readable character and keep the full string on the RFQ and carton label.


Can another solenoid with the same voltage replace 1502ES-12C7U1B2S1?

Voltage is only one control point. The replacement must also match mounting style, plunger thread, energized direction, terminal arrangement, grounding, boot clearance and required force. Compare the complete code and removed-part dimensions instead of selecting from coil voltage alone.


What causes a start-then-stop fault on a pull/hold solenoid?

The pull circuit may move the plunger during cranking while the hold circuit fails after the start signal is released. Measure hold-terminal voltage under load, inspect relay logic and connector resistance, and confirm the plunger reaches full travel before replacing the solenoid.


What should be compared with the removed 1502ES-12C7U1B2S1 assembly?

Compare the full label, voltage, connector face, terminal count, mounting-hole centers, body orientation, output end, resting length and required travel. Add one wider installed photo showing nearby pump or linkage clearance; close product photos alone may hide the geometry that decides fitment.


How can repeat coil damage be avoided after replacement?

Correct the reason the old unit failed before installation. Check supply voltage, pull/hold timing, linkage resistance, mechanical stops, terminal tightness and heat exposure. A new coil can fail quickly when the pull stage remains energized or the plunger cannot complete its designed stroke.


What information should a distributor include in the 1502ES-12C7U1B2S1 RFQ?

Send 1502ES-12C7U1B2S1 / 1502ES-24C7U1B2S1 / 1500-1004, confirmed voltage, Woodward 1500-1004 diesel control systems, old-label and connector photos, bracket and output measurements, quantity, destination and packing requirement. Mixed fleets should list each voltage and configuration on separate lines so technical approval and warehouse labeling remain traceable.
