Key Information

  • Part Number: 1064689-00-J.
  • Product Type: High-voltage battery pyrotechnic disconnect / battery pyro fuse replacement part.
  • Vehicle Application: Tesla Model 3 / Model Y, depending on VIN, production year, market region and battery configuration.
  • Current Page Fitment Text: Fit for Tesla Model 3/Y 2017, 2018, 2019, 2020, 2021 and 2022.
  • Repair Use: For replacement when the original battery pyro disconnect is diagnosed as failed, triggered, damaged or requiring service.
  • Professional Installation Required: This is a high-voltage safety component and should not be installed by untrained users.
  • Not A Regular Fuse: Do not confuse this with a standard blade fuse, ignition fuse, 12V fuse-box part or DIY electrical accessory.
High-voltage safety warning: installation must be performed by a qualified EV technician or Tesla service professional. Incorrect handling of high-voltage battery components can cause vehicle damage, severe injury or death.
Verify VIN fitment, original part number, battery pack type, required bolts or service hardware, and the correct service procedure before checkout. Model 3 / Model Y alone is not enough for high-voltage battery repair parts.
This product includes the replacement battery pyro disconnect fuse only. Tesla vehicle, HV battery pack, bolts, service insulators, diagnostic tools, installation labor and other accessories are not included unless clearly stated in the final package contents.

What This Part Is Used For

A pyrotechnic battery disconnect is part of the high-voltage battery safety system. It is used to disconnect the HV battery circuit under specific fault, crash or safety conditions. Because it is safety-related, this page should be written like a repair-part page, not like a normal Tesla accessory page.

  • HV Battery Safety Function: Related to high-voltage battery disconnection, not ordinary cabin power.
  • Diagnostic-Driven Replacement: Replace only after proper diagnosis confirms this part is required.
  • VIN-Specific Fitment: Battery configuration and service procedure can vary by model year and pack type.
  • Service Procedure Required: Proper high-voltage disabling, PPE, insulated tools and post-installation checks are required.

Fitment Must Be Verified By VIN And Part Number

For high-voltage repair parts, broad model names are not enough. Customers should compare the removed part, confirm the printed part number, and verify the vehicle through VIN or service documentation before ordering.

Check Point What Customers Should Confirm
Part Number Confirm 1064689-00-J is the required replacement part for the vehicle.
Vehicle Confirm Model 3 / Model Y compatibility by VIN, production year and service information.
Battery Configuration Confirm the pack type and service procedure for the specific vehicle.
Connector / Terminals Compare connector position, metal terminal shape, mounting holes and housing structure with the removed part.
Service Hardware Confirm whether new bolts, insulators or related hardware are required and whether they are included.
Installer Use a qualified EV technician or Tesla service professional.
Do not order based only on “Model 3 / Model Y.” Compare the original part and confirm fitment before checkout.

Installation & Service Notes

This component should not be positioned as a DIY accessory. High-voltage battery work requires proper safety procedures, insulated tools, PPE, diagnostic checks and post-installation validation.

  • Diagnosis First: Confirm the issue with proper Tesla-compatible diagnostics before replacing the part.
  • High-Voltage Safety: Follow the correct high-voltage disabling and safety procedure before any work begins.
  • Qualified Installer: Installation should be performed by a qualified EV technician or Tesla service professional.
  • Correct Hardware: Confirm whether new bolts or service insulators are required for the repair.
  • Proper Torque: Use the correct service-manual torque procedure and insulated tools.
  • Post-Repair Check: Clear faults, measure required joints where applicable, and confirm normal vehicle operation after repair.
  • Do Not Bypass: Never bypass, modify, probe or reuse a triggered pyrotechnic disconnect.
Never open, modify, bypass, bench-test or probe a pyrotechnic battery disconnect with improvised tools. Incorrect handling can create serious safety risks and vehicle damage.
