Tesla Model S/X GEN3 Charger
The Tesla GEN3 is a single/three phase AC charger that was fitted in the Model S starting with the 2016 'facelift' model. The GEN3 has been fitted on all Model X models.
It is 566mm long, 360mm wide and 90mm high, without the water ports on both small sides. On the underside there are 8 M6 threads to attach.
P/N 103564701C device is 3phase EU version of 72A output charger! On the outside you can distinguish it by a sticker on the side which says 3PH
Charger with top cover removed
Step 1, to confirm all modules charger work you can connect 12V between top and bottom leftmost pins of the LV connector. Every modul lits its standby LED.
Step 2, was to remove internal components from contactor box in front of the modules. There are DC rails, AC rails, fuse and contactors which we will not use.
Step 3, inspect each power modules contact points with control board. This is where we will apply new wiring to be able to control the charger. See wiring table of module pinout.

Low Voltage Connections
The "vehicle side" connector has digital inputs and outputs, these function the same as the Gen2 inputs and outputs:
| Pin | Signal | Gen2 Name |
|---|---|---|
| 3 | Output 1 | OUT1 - HV enable |
| 4 | Output 2 | OUT2 - AC present |
| 5 | Input 1 | input "D1" enable |
| 6 | Input 2 |
The other connections are named the same or have clearly identifiable functions.
The outputs will not output 12v, they are low side switches. If you require a 12v ac present signal then use a relay with its coil switched from the relevant pin.
Software
Software is the same as the Gen2 Tesla Charge V5 boards
