Tesla Model S: 200A Fuses - Wall Connector (Remove and Replace) - Installation
Installation
- Clean the contact surfaces of the new upper and lower bus bars
with alcohol wipes.
- Position the new inner fuse. Install the screw at the L2
terminal (torque 3 Nm).
- Install the inner wire's ring lug on the inner contactor stud.
Caution: Position both ring lugs so that the wires
point toward the front of the unit at a 45-degree angle,
allowing a gap between the inner wire and the outer bus bar.
The wires must not touch the bus bars directly.
Caution: Always install the bus bar first and the ring
lug second. Installing the ring lug first can result in
excessive resistance and overheating.
- Hold the inner wire in position while tightening the nut (torque
5 Nm).
- Use a paint or ink pen to mark the torque position after
reassembly, using a different color than manufacturing
(manufacturing usually uses yellow). Use one continuous motion to
mark the bolt, washer, nut, and bus bar.
- Reinstall the insulator sheet at its original location.
- Repeat steps 2-5 using the L1 terminal for the outer fuse.
- Ensure that the ring lugs are correctly reinstalled to the same
location they were before beginning this procedure.
- Use a multimeter to check the resistance between terminals L1
and L2. The resistance should be at least 100 KOhm. If the
resistance is less than 100 KOhm, check for an electrical short due
to improper installation or defective insulation.
- Reinstall the Wall Connector's cover and security screws.
- Turn on the electricity at the circuit breaker.
- Check the front diagnostic lights on the Wall Connector cover.
When it is not plugged into the vehicle, the topmost green LED
should be steady (not flashing).
- Charge the vehicle with the Wall Connector for 2-3 minutes to
verify proper operation of the Wall Connector.
