🔧 Installation & Safety Guidelines

  • Critical Safety Warning: Only certified technicians who have completed Tesla high voltage certification training should perform this repair. This procedure is not mobile capable and requires proper shop equipment.

  • Always wear proper personal protective equipment (PPE) including Class 0 (1000V rated) high voltage insulated gloves, leather overgloves, and safety goggles when working on high voltage battery systems. Remove all jewelry and metal objects before starting work.

  • Always disconnect low voltage power before beginning any high voltage system work.

  • After installation, verify resistance is within the acceptable factory range: 0.050mΩ (50 microohms) to 0.195mΩ (195 microohms) using a Hioki RM 3548 microohm meter.

  • After physical installation, connect a laptop with Tesla Toolbox software, navigate to High Voltage > Procedures > Shunt Replacement > Write Shunt Resistance, input your measured resistance value (in nΩ), select Cyntec as the shunt type, and run the calibration procedure.

  • After calibration, perform a battery health test through your vehicle touchscreen to confirm proper operation.
