It has been a couple of months so I guess I should update: To this point, the on board charger with the replaced capacitors and the swapped cooling components is continuing to perform as expected without errors. The car charges, and let’s be honest, that’s enough! In order to guarantee that...

I know it’s been a few days so I wanted to give an update… Yesterday I got the old component desoldered from the board and replaced the capacitor on the bottom board with a new one. It’s not a process I’ve ever done before, so it took me a while to get it done and I ultimately had to...

Update on the Frankin-charger: I got all of the components removed that need to be transplanted from the used charger chassi with the blown capacitor and coolant leak to the chassis from my original charger Without the coolant leak. I have figured out that the white box on the side is extremely...

Upon further review, I don't think the seller is going to make me send the unit back, and I feel like I have to do ALL of my due diligence before spending $1,400 on a new OBC, so I'm getting my multimeter back out! I'll likely pull the board tonight or tomorrow depending on time. I'm planning...

After talking with the seller, and much debate, I’m going to send the used charger back. I am leaning toward buying a new one (at twice the cost unfortunately). While it’s possible that I am only a few minor repairs from fixed with the used unit, it’s also possible I go down a winding road that...

I’m still awaiting word from the seller so I haven’t proceeded any farther yet buying capacitors or further dismantling the OBC. When the time comes, do I need to swap out the beige colored boxes between the two units as well? I can easily open up my EVSE. I will take some pictures and send...

I woke up this morning more positive than last night. I decided that if they tell me to keep the 2x broken OBC, that I’ll try to fix it. Considering it’s expensive to ship back a 2x broken part that they are unlikely or unable to fix, I feel like the odds are relatively good. That means I’m...

Update: my Friday night plan to Frankenstein a charger has hit a smelly snag. Looks like we had a failure in progress as we already had at least one explosion. I immediately noticed the discoloring and the smell when I opened it up and I’m frankly shocked that it was still charging the car...

I figured I would update everyone on the progress… Last week I got the new onboard charger installed and it is charging the car, but unfortunately it is leaking coolant. I have spent the last few days trying to make sure that it wasn’t just “user error“ on my installation and I have finally...

I got the replacement charger installed in the car tonight. It is presently charging using my 240v EVSE. I refilled the coolant, but I noticed that the replacement on board charger was rather warm. I imagine that’s to be expected, but I measured somewhere in the neighborhood of around 90 to...

So… In a fortunate and surprising turn of events… My onboard charger is going to get here early… Probably today. Considering that I have a new 12V battery, and based upon what we know so far, is there any reason to believe, that the car will likely cause a failure in the new (used) charger?

Finally got a few moments where my daughter and I could look things over. 1) Fuse F101 - No Continuity 2) Lightning Arrestor - No Continuity Lollypops: Since I don't have letter identifiers, I'll identify them by orientation, since two are aligned, and one is perpendicular. 1) The two that are...

Measured at zero ohms. Resistance gradually builds to 19.7 mega ohms. I think it’s unlikely that lightning was an issue, because I’m a meteorologist and I don’t remember an instance of that, but we do have frequent power disruptions where we live. F101 - no continuity F102 - zero ohms F103...

1) I believe that the L201 inductor could be blown because I got a continuity reading of infinity when measuring it from the pins below the board. 2) I got a reading of near zero ohms on the large black capacitor, so (the non-electrical engineer in me believes that) it looks to be shorted. I...

I hadn’t noticed it until you pointed it out, but on the side of that component, something looks to be fractured, and it almost looks like where you see R108, there is a little soot, as though it burst out that direction.

Thank you, again to everyone who has responded and given their input. 🙏🏻 I wasn’t able to see much, because accurately de-soldering 72 pins is a little beyond what I have time for today (or beyond my expertise, if I'm honest), but I was able to detect the location of one component that failed...

Upon further review, my piece looks exactly like a part of this "Waffle Plate." I'm guessing it's pretty likely that I'll be buying a new onboard charger. I talked to an engineer I work with, and when I showed him a picture of the piece of the component and the waffle plate side-by-side, he...

I decided to work on the charger myself. Getting it out took a bit, and I disconnected more than probably necessary underneath the car, just to be safe, but it is out and on the bench. When I opened up the onboard charger, shards of black components were rattling around on the back (below the...

Thank you for your response. Unfortunately, after reading through everything that I have, though I have limited experience with this, I agree... the B2840 is not a good sign. I would like to at least attempt to fix the charger. If I can’t, I would like to replace it myself and save all that...

I am also having the exact same two error codes that do not clear: B2840 962E CHARGER On Board Charger P3173 00C0 EV/HEV On Board Charger Sys My 2012 Leaf with 88k miles throws a fault on the trickle charger and will not charge on it or our L2 First Gen JuiceBox. When I plug it in, it beeps...
