Tesla Wall Charger Communication error

5520 Views 23 Replies 8 Participants Last post by  GJETSON
I have a Tesla Wall Connector that I installed last year & have been using the JDapter with no issues up until the last week. I've since developed an intermittent communication error (6 red flashes on charger) that either doesn't allow charging or shuts off charging if it has started. I had the fortunate opportunity to try another, not as used, JDapter last night and no issues.
Anyone else experience similar problems & if so, what the fix was? Plugs, terminals, receiver etc. all look fine.

So the adapter is only useful if there is no J1772 L2 or CCS around?
The adapter allows you to use the versatile Tesla Gen II EVSE. You can also use it on Tesla destination chargers. If you don't own a Tesla Gen II EVSE, and don't intend to use a Tesla destination charger in a pinch, it is of no use.
It only makes sense if I were to ever go on a road trip and there was zero J1772 or CCS available...which is highly unlikely.
Or, if like us, you have a Tesla Gen II as your home, and travel backup EVSE.

We have had this happen perhaps three times in over two years. I unplug the JDapter from the car, push the Tesla plug into the back of the JDapter with more pressure, and the communication pins again make contact. I then plug it into the car, and all is well.

If it continues, try some electrical contact cleaner spray.
With the Teslatap I think it鈥檚 a moisture issue.
Wow! Not sure how I ended up responding to an 11 month old post. Sorry.
I was the one who had originally brought this one back from the dead. :)

I thought @SudBolt had a Teslatap, but now I see he has a Jdapter. Hopefully my issue will clear up with my Teslatap or its going back.
Is your EVSE outside? Our JDapter lives an easy life in a garage.
Yes we have 2 Tesla wall connectors outside where the bolt stays and one inside.
I thought about putting a section of fat bike inner tube over the Tesla plug and JDapter, cinched up with zip ties, if I was going to use it outdoors a lot.
