Frequently Asked Questions
Q: What is the 00591-09248-81 yellow connector housing used for?
A: The 00591-09248-81 is an OEM SB175 series connector housing in yellow for Toyota electric lift trucks. The yellow color designates a specific polarity configuration. It is rated for 175 amp charging circuits on small to mid-size electric pallet jacks and hand trucks. Color coding ensures correct charging circuit alignment and prevents equipment damage.
Q: Are the gray, blue, and yellow SB175 housings electrically identical?
A: No. While all three housings fit the same SB175 connector family and handle 175 amps, the color indicates internal pin polarity. Gray, blue, and yellow connectors are keyed for different charging circuit configurations. Mixing colors causes reverse polarity, which damages the vehicle charger circuit and battery management system.
Q: Can I replace a broken yellow 00591-09248-81 housing with a blue or gray housing?
A: No. You must use the same color housing that matches your vehicle and charger system. Using the wrong color housing creates a polarity mismatch. The connector may physically fit but electrical connections will be reversed, causing immediate charger failure and potential fire hazard. Always match the original housing color.
Q: How do I know if the yellow 00591-09248-81 housing is the correct replacement for my truck?
A: Check the existing connector color on your vehicle. If it is yellow, then 00591-09248-81 is correct. Verify your charger plug is also yellow and that the vehicle operates at 175 amp charging capacity. If you are unsure of your connector color or amperage rating, contact us with your vehicle model and serial number.
Q: What material is the yellow 00591-09248-81 housing constructed from?
A: The yellow housing is molded from impact-resistant polymer, the same material as the gray and blue versions. This plastic compound resists cracking from impact and temperature extremes. Internal pin contacts are silver-plated copper for corrosion resistance and reliable current flow.
