Frequently Asked Questions
Q: What makes and models is the TO 00591-51691-81 contactor compatible with?
A: The TO 00591-51691-81 contactor is specifically designed for Toyota electric lift trucks and warehouse vehicles. It is not compatible with non-Toyota material handling equipment due to unique connector configurations and mounting specifications.
Q: What materials are used in the TO 00591-51691-81 contactor?
A: The housing is made from high-impact thermoplastic to withstand vibration and harsh warehouse conditions. The contact pressure spring is constructed from heavy-duty wound steel, ensuring consistent contact force. Main contacts are made of silver-alloy for reliable current flow in the primary power circuit.
Q: How can I tell if the TO 00591-51691-81 contactor needs to be replaced?
A: If the truck does not respond when the accelerator pedal is pressed or the motor fails to engage, test the coil voltage with a multimeter. If 24VDC reaches the coil but the motor does not start, the contactor contacts may be welded or stuck open. Replace the entire contactor unit as contacts cannot be repaired.
Q: What is the function of the TO 00591-51691-81 contactor in the electrical system?
A: This contactor serves as the primary power disconnect and engagement switch for the drive circuit. When the operator activates the accelerator pedal, the 24VDC coil energizes and closes contacts to connect the battery to the motor. It also acts as a safety disconnect when the truck is idle or powered off.
