Need help diagnosing a failed Blink EVSE

Mon Jan 05, 2015 8:43 pm

I'm thinking of repairing my unit myself since service seems to be non-existent. Mine is around 4 years old. When I returned from a recent trip, the screen was blank and unit not working. After searching around here, I tried the disconnection of the blue cables to create a dumb unit, but when I plugged it into my Leaf, the upper dash lights did not go into their sequence and when I pushed the manual charging button on the dash, nothing happened. Anyone have any ideas what to do next? Any help is much appreciated.

If all else fails, and use the housing and cable and tear out the rest.
Buy an OPEN EVSE board, and stick that in there.
Good luck.
I have a Blink, and I hope it keeps on chugging, but I have an Open EVSE board already so when it dies, I'm ready :D

I'd open it up, and check connections. Look for anything that looks like it got hot or burned. I would also echo KillaWhat, and go the OpenEVSE route if a solution is not forthcoming. I know that Chris was specifically experimenting with refitting Blinks and I'm sure he'd know exactly what you'd need to rebuild it with OpenEVSE parts.

That is one option.
But the old Blink units have multiple risks.
My SD card corrupted several months back, and currently is working as a dumb EVSE.
But other thread indicates 43% eventually have main board failure which the OP probably has.
They also have bad REVA cable crimp concerns, and inadequate power connection concerns.

For me if mine dies either evseupgrade or an Open EVSE new build by GlennD is probably a better choice.

I looked around inside for signs of anything overheating or loose connections and could not find anything. If there is no other way to narrow it down, I may have to bite the bullet and get a new unit which I need to research. Seems the Open EVSE gets positive remarks here and I think the Clipper as well.

I know it's probably a silly question, but did you check the circuit breaker?

IMHO how could anyone but the truly gullible believe "43% [of Blinks] eventually have main board failure" be true in any meaningful way?

On the other hand there IS some truth in "100% of electronic circuit boards eventually fail", but it is not very meaningful to me in my lifetime.

...

I don't know if it is accurate or not.
In the other thread:

...


So the Blink representative said 43% failures per braebyrn.
But that may be all failures, not just primary circuit board failures.

Chris of OpenEVSE fame did awesome conversion using the case and J1772 cable. He did custom graphics and it looks factory. Silk screening is beyond me but I can admire the results.

Currently you can get a OpenEVSE ver 2.5 board for $69 shipping included. This is a stand alone board that just requires a GFCI coil and a J1772 cable and both can be salvaged.

All it takes is some basic skills and a little bit of common sense. We have a preponderance of tech geeks on this forum. Help is readily available.
