Frequently Asked Questions

Q: What is the voltage and operating current for part number 00591-41439-81?
A: This is a 12VDC solenoid with a nominal operating current of 2.2 amps at 12 volts. It is rated for continuous duty operation, meaning it can run constantly without thermal damage in normal warehouse conditions.

Q: What function does this Toyota solenoid perform in an electric lift truck?
A: This solenoid is used in main contactor applications to control hydraulic pump operation and directional valve shifting. It energizes or de-energizes the contactor coil to start, stop, and direct fluid flow for lifting, lowering, and mast tilt functions.

Q: What does stud terminal mean on this solenoid?
A: Stud terminals are two threaded posts extending from the solenoid coil that accept wire connections. Connections are made using ring terminals and fasteners rather than plug connectors, providing a secure, vibration-resistant electrical connection.

Q: Is the 00591-41439-81 solenoid compatible with other lift truck brands?
A: This is an OEM Toyota solenoid. While the voltage and current ratings may match solenoids from Crown, Raymond, or Yale, physical dimensions, terminal styles, and mounting brackets vary. Verify compatibility before ordering for non-Toyota equipment.

Q: What happens if this solenoid fails?
A: A failed solenoid prevents the contactor from engaging, so the pump will not run and the lift truck will not operate. The solenoid coil will not energize when the control switch is pressed. Replace the solenoid to restore equipment function.
