Solenoid Control Module 3339888 SA-4822 for Woodward pull/hold shutdown solenoid systems

3339888 Solenoid Control Module for Pull/Hold Systems

3339888 manages electrical power to a shutdown solenoid in Woodward pull/hold shutdown solenoid systems. It is a control accessory rather than the moving shutoff solenoid itself. Correct selection depends on input voltage, solenoid winding arrangement, load current, actuation timing, terminals and wiring logic. Confirm the complete module reference and circuit before substitution.

Electrical Compatibility Review for 3339888

Match the complete stamped reference because voltage, winding, mounting, terminals, output geometry and duty can differ within the same family.

Diagnosing the Module, Solenoid and Harness Separately

Check the electrical command, component response and final mechanical movement as separate observations. This prevents a wiring, control-module or linkage fault from being mistaken for a failed replacement part.

3339888 Replacement Approval Checklist

Release the order only after electrical, mechanical and application evidence agrees with the removed assembly.

3339888 Technical FAQ

How should the voltage versions of 3339888 be separated?

Keep the complete voltage-specific reference and old-unit marking on every order line. Similar housings do not make different coils interchangeable. Measure system voltage at the original connector during operation, then label inventory by both OE and voltage so mixed fleets cannot receive the wrong electrical version.

What should be checked on Woodward pull/hold shutdown solenoid systems before ordering 3339888?

Use 3339888 / SA-4822 as the first control, then compare the old label, voltage, connector face, mounting-hole centers, output end and operating direction. Record the engine or machine model and serial number, but do not use the model name alone because production changes can introduce another shutdown arrangement.

What does the 3339888 module do in the shutdown circuit?

It manages the high-energy actuation stage and the lower-energy holding stage used by many shutdown solenoids. The module does not replace a mechanically failed actuator. Confirm input power, control signal, output voltage and the solenoid winding arrangement so a wiring or coil fault is not misdiagnosed as a module failure.

Can 3339888 be wired by matching terminal position only?

No. Identify supply, auxiliary control, pull, hold and ground functions from the original circuit. Terminal position and wire color can change between modules. An incorrect connection can prevent pull-in, leave the high-current stage active or damage the module and solenoid.

Why can a new module still produce a start-then-stop symptom?

The module may energize the pull stage while the hold winding, harness or control input remains open. Measure the output through the transition from cranking to run, check connector resistance and test the solenoid windings. Replace the module only after those three sections are isolated.

What should be compared with the removed 3339888 assembly?

Compare the full label, voltage, connector face, terminal count, mounting-hole centers, body orientation, output end, resting length and working travel. Include one wider installed photo showing pump, lever or surrounding clearance because close product images can hide the geometry that decides fitment.

How can repeat electrical or coil damage be prevented?

Correct the original failure cause before installation. Check supply voltage, pull/hold timing, linkage resistance, mechanical stops, terminal tightness, heat and moisture exposure. A new unit can fail quickly when the high-current stage remains energized or the output cannot complete its designed stroke.
