Frequently Asked Questions
Q: Is the 1500910-12 compatible with EV-100 electric lift trucks?
A: The 1500910-12 is a contact kit for EV-100 series electric lift trucks. Confirm your equipment uses the EV-100 control system before ordering. Verify the part number in your equipment documentation to ensure correct fitment and avoid control system malfunction.
Q: What happens if contact surfaces become pitted or discolored?
A: Pitting and discoloration indicate electrical arcing and erosion of the contact material. This increases electrical resistance and reduces current capacity. Pitted contacts cause motor sluggishness, slow lift speed, and intermittent control response. Replace the contact kit immediately upon visual inspection of pitting.
Q: Can the 1500910-12 contact kit be cleaned instead of replaced?
A: Contact kits are not field-serviceable or cleanable. Once pitted or corroded, contact surfaces cannot be restored to original electrical conductivity. Replacement with a new contact kit is the only reliable solution. Attempting to clean contacts risks incomplete restoration and continued electrical problems.
Q: What is the amperage rating of the 1500910-12 contact kit?
A: The 1500910-12 is rated for the EV-100 system specifications. Confirm the amperage and voltage ratings in your equipment documentation match this part number. Installing a contact kit with incorrect electrical ratings causes overheating, nuisance breaker trips, and premature contact wear.
Q: How do I verify the 1500910-12 is the correct replacement for my lift truck?
A: Check your equipment serial plate and control system documentation for the required part number. Cross-reference your equipment model and control system type against manufacturer specifications. Provide your equipment make, model, and serial number when ordering to ensure compatibility.
