Standard Ignition BSC127 Battery Current Sensor

Battery Current Sensor for GM Charging Systems

Standard Ignition BSC127 is a complete battery current sensor assembly for vehicles with monitored charging systems. It provides the battery current and voltage sensing input used by the vehicle’s electrical control strategy, helping maintain accurate charging system operation.

• Battery current sensor complete assembly
• Female plug-in connector with rectangular housing
• 3 male mini-blade terminals
• Direct replacement style for monitored battery charging circuits
• Standard Ignition BSC127 application-specific electrical component

Fitment and Application Details

Compatible with 2015 Chevrolet Impala, battery current / volt sensor location, and 2014-2015 Chevrolet Malibu, battery current / volt sensor location. This Standard Ignition BSC127 sensor is built for the charging system architecture used on these GM applications and is listed for direct vehicle-specific service. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Use BSC127 when servicing the battery current sensing circuit on Chevrolet Impala and Chevrolet Malibu models that rely on current and voltage feedback for charging control. The part number BSC127 is also a useful reference when matching the correct sensor by OE-style application.

What This Sensor Helps Address

• Charging system warning lights related to battery current sensing
• Incorrect battery current or voltage feedback to the control module
• Charging performance issues caused by a failed sensor assembly
• Electrical diagnostics that point to the battery current / volt sensor circuit
• Replacement needs after connector or terminal wear in the sensor assembly

Installation Notes and Tips

Verify connector style, terminal count, and OE application before installation. The BSC127 uses a female plug-in connector, rectangular connector shape, and 3 male mini-blade terminals, so the replacement should be matched carefully to the original sensor configuration. Confirm the vehicle is a 2014-2015 Chevrolet Malibu or 2015 Chevrolet Impala with the battery current / volt sensor application before service.

Quality Assurance

Standard Ignition supplies electrical components for service replacement use, and this BSC127 sensor is offered as a complete assembly for the listed GM applications.
