Frequently Asked Questions
Q: What is the BJ 005656 contactor rated for and what circuits does it control?
A: The BJ 005656 is a 12VDC double pole contactor rated for continuous duty operation. It is engineered specifically for traction motor circuits and forward/reverse directional control in Big Joe PDH series electric lift trucks. The double pole configuration allows simultaneous switching of multiple power circuits required for motion control.
Q: What are the contact materials and terminal configuration on this contactor?
A: The BJ 005656 features copper alloy contacts, which provide reliable conductivity and resistance to arcing under continuous duty loads. Terminals are configured for direct panel mount replacement, meaning the stud or connection points align directly with the original equipment mounting holes on compatible Big Joe models without requiring adapter plates or rewiring.
Q: Which Big Joe electric lift truck models use the BJ 005656 contactor?
A: The BJ 005656 is designed as an OEM contactor for Big Joe PDH series electric lift trucks. PDH models include walkie stackers, pallet trucks, and order pickers from that generation. Verify your model designation and serial range match PDH specifications before ordering, as contactor compatibility can vary between product lines and years.
Q: How do I identify when the BJ 005656 contactor needs replacement?
A: Symptoms of contactor failure include: loss of forward or reverse motion while other truck functions operate normally, intermittent movement that hesitates or cuts out during operation, audible humming or buzzing from the contactor under power but no motor engagement, or visible burn marks and pitting on the copper contact surfaces. Any of these indicate the contactor coil or contacts have failed and replacement is required.
Q: Is the OEM part number 005656 the same as the SKU BJ 005656?
A: Yes. The OEM part number is 005656 and our SKU is BJ 005656, where BJ denotes the Big Joe manufacturer. When ordering or cross-referencing, both designations refer to the same contactor. Always verify the 12VDC rating and double pole configuration match your equipment specifications.
