Frequently Asked Questions
Q: What does the 78917-GE contact component do?
A: The 78917-GE is an electrical contact used in lift truck control circuits. It completes or breaks electrical connections to manage motor, solenoid, and charging functions.
Q: How do I know if the 78917-GE contact needs replacement?
A: Common failure symptoms include intermittent power loss, slow motor response, failure to engage brakes or hydraulics, and burned or pitted contact surfaces. If the contact appears corroded or arcing damage is visible, replacement is necessary.
Q: What equipment models use the 78917-GE contact?
A: The 78917-GE is used across multiple electric lift truck models from major OEMs. Verify your equipment model and control circuit specifications to ensure compatibility before ordering.
Q: Why do electrical contacts fail?
A: Contacts wear through electrical arcing during normal switching cycles. Corrosion from moisture, dust, and salt spray accelerates failure. High current spikes and inadequate contact pressure also reduce lifespan.
