Roadster charging

Is the battery bricked, or does the touch screen turn on?
Not really since the charge connector is proprietary, but with an adapter you could use a charger with a J1772 connector.
many options but heres the easiest, a canSr and a tesla UMC. That gives you 120v 10-16A and 240v 12-32/40A
Then if you want a faster charge get a HPWC for around $400. The roadster plug is proprietary and without an adapter you will be searching for something thats hard to obtain. A CanJr will give you access to J1772 chargers which may be more or less of a benefit to you. I would say a good majority of us have in their possession CAN Jr and Sr, a UMC for road trips, a HPWC or Open EVSE for home use. Plugging a UMC or any 14-50 repeatedly is not ideal as the plug and socket designed for maintenance and occasional replacement rather than a daily process so a static charger at home would be a more ideal situation. Again if the battery has not been charged in a long while and the service disconnect was not pulled, don't expect a simple charge process, it could well have effectively bricked the battery and there are few options of recovery without spending many thousands of dollars.

Tesla doesn't make any adapters from Tesla2 -> Roadster, so you're looking for an aftermarket solution called the CANSR.

I see you sell a Can Jr. Will that work for me or do I need to look for a Can Sr?
I have instructions I email to owners all the time for this process. In a nutshell, you apply 12V power to the APS leads in the back of the Roadster and then use the touchscreen to put the Roadster into Tow Mode. The TCM requires 12V power and a particular CAN message to unlock the parking pawl in the transmission.
They are in front of the rear right wheel. Once the wheel and wheel arch liner are removed you will see a ground point on the side of the frame. That's where your ground lead/cable is at. It's the thickest gauge wire there. The positive lead/cable is in the small black box towards the front of the Roadster. You will see a heavy gauge wire on the right with a ring of red heat shrink, and on the left is the APS positive lead/cable which will look like your negative except it will have a ring of red heat shrink.
Let me know if you still can't find them.
Thank you Peter
Question I have a newer model 40amp 115
Tesla charger
What voltage readings should I get checking the out put? I get 11.75 BEC on small pins and nothing on the two large pins?
Is the charge bad or is the a signal required from the car?
Also right now I don’t what to spend $ for a can Dr since the car was a salvage car I’m hoping you can they’ll me the pin outs on the Tesla charge and the pin inputs on the roadster charging port?
That's normal. The ~12V is the pilot signal from the charger to tell the Roadster a power supply is present and ready to send power when the Roadster is ready. The two larger pins on the charger will not energize with 240V until that handshake has completed.
You can look for a Roadster yellow spare connector. They are 120V and are usually less costly. Otherwise, the pin out for the charger is not something you want to fudge at the charge port. Open the PEM service window on the passenger side of the PEM and you will find the connections from the charge port to the PEM. Add ring terminals to your charger wires and you can tap directly into the PEM line inputs.
I wouldn't condone this, so tread carefully.
So peter we are talking about connecting to terminals Ac1 and Ac 2 in the set port which appear to go to charging port correct?
But how to get the charger to output voltage?and what should it be?
