Product Description
SOLENOID (12 VOLT)
Frequently Asked Questions
Q: What is the voltage rating of the 504903802 solenoid?
A: The 504903802 is a 12-volt solenoid for electric lift trucks operating on 12-volt electrical systems. Do not confuse this with 24-volt solenoids. Using a 12-volt solenoid on a 24-volt system or vice versa will cause immediate failure and damage. Verify your truck voltage before ordering.
Q: How does the 504903802 differ from 24-volt solenoids like the 5049038-01?
A: The 504903802 is rated for 12-volt systems while the 5049038-01 is rated for 24-volt systems. These solenoids are not interchangeable. A 12-volt solenoid coil has different resistance and magnetic characteristics than a 24-volt solenoid. Applying the wrong voltage damages the coil and renders the solenoid inoperative.
Q: Which truck models and manufacturers use 12-volt solenoids like the 504903802?
A: Certain compact and light-duty electric pallet jacks use 12-volt systems and solenoid controls. Confirm your truck is specifically designed for 12-volt operation. Check your truck manual, battery specification, or existing solenoid markings to verify voltage before ordering the 504903802.
Q: What signs indicate the 504903802 solenoid is failing?
A: Failure symptoms include no response to lift/lower/tilt controls, weak or slow hydraulic action, audible clicking without corresponding movement, or intermittent function. If the truck battery is charged and electrical connections are clean but the solenoid does not respond, the solenoid coil likely requires replacement.
Q: How do I verify the 504903802 is the correct replacement for my equipment?
A: Check your truck manual for the original solenoid part number and voltage specification. Confirm your truck battery is 12 volts, not 24 volts. Cross-reference the failed solenoid markings against the 504903802 to ensure voltage and connector type match. Using the wrong voltage solenoid causes immediate failure.
