I have an EVSE whose internal Circuit Board is beginning to fail. The overseas manufacturer will send me a new board for free and they are offering to pay for the cost of having a repair shop stateside put in the new board and I guess solder it back together. Does anybody know of a shop that would do that kind of thing? My other option is to send the entire unit back, but the shipping cost will be high and it will take a good while. Any ideas? thanks

I know of none. Look up electronic repair shops in your area? Soldering is not hard and the equipment inexpensive.

If it's not too hard to rewire the thing together I might even try it myself. I'm not sure that I would need to solder it anyway -- I have to look and see. If I can do it myself I will.

Soldering is probably one of the easier DIY electronic jobs out there. Most hand held "wand" type soldering irons are sufficient, but occasionally you'll find they just don't get hot enough (30w usually) and you may need a 50 or 100w iron. For the circuit board on the EVSE, a 30w iron should be enough. Just make sure you take your time and verify that you don't solder two adjacent terminals. If this is your first time doing this job, I'd suggest taking high res close up shots and comparing the before and after images of everything you solder to make sure it's right and nothing got connected to the replacement solder points that shouldn't have.

Correct. It may be screw-down connectors. Open the case and look at how the wires from the wall plug and the wires from the cord that goes to the car connect to the circuit board. That will answer the question.

The catch is that the wires are pretty large diameter. That can be harder to solder than small wiring. Forum member Chris TX has a lot of experience tearing into EVSEs and soldering these wires. I think he even has a tutorial posted here on converting the 2013 EVSE to level 2, which involves soldering.

Thanks. I actually reached out to Chris, because he has opened this particular EVSE before, and may know what it's going to take to replace the board....As was said, it might just be a screwed rather than a soldered connection, which would be easier for me to deal with myself.

Here's the Voltec 240V EVSE I gutted and put a new board into. The incoming and outgoing lines are attached via set screw blocks (no soldering):

Thanks I haven't opened up the unit yet but Chris already did. I will this weekend. I can't tell from this how the connections are to be done.

Marcus M, PM me. I repair and solder mil-spec parts for the DoD. High reliability soldering certification. I'll do it for free if you're close by or if you want to mail it and of course pay the shipping.

We use PRC 2000's and the NAVSEA 00-25-259 soldering workmanship standards (that's a technical order/manual, same as nasa uses for whatever that's worth). It would help me out to repair it for you because I'm considering buying some evse equipment myself and I wouldn't mind seeing the original workmanship standards/quality of the circuit card/cards before buying myself.

Thanks so much wBronze. If I strike out nearby (in DC area), I'll be back in touch for sure. Now that I looked more closely I'm hoping the J connector is just acting up. I just used a plastic tool to open up some of the connectors a bit. When I opened it up it looked like the Board itself and its connections to the wires was ok but I don't have a way to actually test it to know for sure....I'll advise, and thanks again for the offer.
