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.

I seem to recall that the adapter instructions say that you should plug the adapter into the charger before you plug it into the car. Or maybe it's vice versa? Whichever way you've been doing it, it might be worth trying the opposite way and waiting for 30 seconds between plugging the first pair together and the second.

Yup, plug Tesla cord into adapter and wait 30 sec before plugging in car... but he has been using it for a long time just fine, and a different adapter worked for him, so I suspect the adapter is the problem.

OP: Where did you purchase it from? I know that the Tesla Tap I purchased through Amazon has a 1 year warranty... and I looked up the J-dapter stub on Amazon and it also has a 1 year warranty. If you have had it less than a full year, contact who ever you got it from for a replacement.

Starting to think it's the adapter. Gave it another good charge last night with the borrowed adapter and all went well. I'll try again with mine and see what happens.
Thanks.

This is another sticky issue with EV's in general. Clearly, people have to get accustomed to the limitations of range, speed to charge, where you can charge, planning lunches that you really wouldn't take but you'll lie to yourself and tell all of us and yourself you read a book, ate a sandwich and found God for a charge on the 200 mile trip, but the one aspect that will give a bad rep to the technology is flat out failing to get a charge. I have talked to people who have been frustrated with the; 'you have to lift the cord, remove tension to initiate the charge' issue and that's manageable for those that are aware of it. However, I'm worried that gremlins in all aspects of failed charging is a black eye that the industry I hope is addressing. I myself have had to move my car from pedestal to pedestal to find a working unit, whether it's a card reader or something else.

In any case, I hope you don't have any issues in the future.

Looks like Nissan has a comment on this particular topic...

Well, after two nice long uninterrupted charges with my original adapter cable, I'm at a loss as to what was causing the communication issues. Carry on I guess.
UPDATE: Went to plug in charger cable after sitting unplugged during a couple of mild damp days. Started charging and then tripped out. Noticed water around plug so tried drying it and same thing. Disconnected adapter cable, dried out what I could but noticed water still coming out of pin area. As soon as I connected it to the Tesla plug, charger would trip out. Dismantled adapter plug and dried out all the water from it. Reconnected and all good. I guess the way I was hanging my cable & adapter allowed water to get in. All good now and changing my hanging habits.

Using this Tesla to J1772 adaptor to charge a Bolt with the regular Tesla charger is more kw than a standard L2 J1772 correct? (9kw I believe rather than 6kw)
Nope, charging is the lower of either EVSE or car. The Bolt is limited to 32A, so 7.2 kW @240V.

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.
Having it would open a large number of free charging locations but realistically the $200 to buy it would almost never break even.

Since it won鈥檛 charge faster than a J1772 that kills my main interest into the adapter.

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.

Did you ever have the issue again? I have the latest 80a version of the Teslatap and just had the red light issue on any of my Tesla wall connectors. It sits outside and it has been cold and damp out. I called umc-j1772 site where I bought it. Guy there said it's def a moisture issue and how its hung when not in use. He said to put the teslatap in the oven on lowest setting for 2 hours to dry it out and then some dielectric grease. I did one hour in the oven at 170*. Plugged it back in and green light. I put a bead of dielectric grease around the connection where the tesla end plugs into the teslatap. I hung it outside in a way so water would not get into that connection. It was rainy and cold yesterday, when our daughter got home at 9p, the red light on the tesla wall connector was on again. So IMO its a dampness/cold temp issue. I currently have it in the oven at 170* for the full 2 hours.

I dont see any water in the pin area, I imagine you are talking about the J1772 side of the teslatap where you saw the water? I also suspect that's the side you took apart, since thats the only side you can disassemble?

TIA!

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.
