Re: Mods for the Blink EVSE ! (was Fix)

Sun Nov 02, 2014 4:46 pm

Bought a used Blink cheap and after 3 charges, it has the red screen. I unplugged the two connectors mentioned in the beginning of this post and it still will not charge. I even tried the timer button on the dash next to the steering wheel heater button and nothing. Any ideas?

I was trying to find which wires need to be resoldered that was mentioned here also, but there is a lot of wires there. Any ideas here too?

I believe one of the common causes of that failure is a poor crimp/etc. on the current transformer that is on on the wires going to the J1772 cord. While there was a whole lot of different things going on when they serviced mine so it was hard to tell exactly what all was replaced I know one of the issues was with that. You should also see people describing an issue with it's placement and getting "interference" from other things and how moving it resolved their issues.

I did remove the crimped connectors on the coil after moving it about 1 1/2 inches away from the terminal block and re-soldered them and no change. Its really sad that I can't even make it a dumb charger!

Tomorrow, I am going to swap in another known working Blink J1772 cord and plug to see if that is the problem. Luckily I have two blink units....Any other ideas?

You did make sure the power cable connections to the Blink are in good shape and haven't overheated, right?
See links earlier in the thread about that issue.

If you have made it dumb and it has power and the J1772 cable is OK, then some component is probably bad and you will have to do detailed component testing to isolate the cause.

But it is possible that the cable is bad. Someone said they had theirs go bad. The design of how it is pushed into a slot for storage is poor and it failed at that point. Mine developed small tear in the flexible rubber piece at that point so I quit storing it in the slot after learning of that failure. Cable lays on box and just drape handle over top of reel. Better for the cable.

Yes, I checked them and looked for heat discoloration. No signs at all. Connections were all tight too.

I removed all crimped connections, soldered the connections, removed and replaced the J1772 cable with a known good working one and still have the red screen. I also again tried to use as a dumb charger, with no luck.

I have a good volt meter but do not know how to individually check components properly. Since I have another good working Blink unit, how would one go about testing each component?

113 volts going into the power supply, but nothing coming out of the bundle of blue wires. Should I be reading low voltage coming out from the blue wire connectors? The fuse is good and has 113 volts on both sides on that board. The other unit is at home, so it looks like I will bring them together and do the testing with them next to each other.......

That was it, thanks Camasleaf and others. Next, where do I get this power supply fixed, or is it just easier to buy another? I don't see any burnt or ballooned components. It says Meanwell.

Here's a data point for you. After I performed the lobotomy operation on my Blink, as per the OP instructions, I have a blank screen. Also mine works great now. Having a red screen is curious.
