I think that temperature sensitive fuse is actually redundant as the resistors themselves do the job quite as well. I burnt several resistors (including the original ones) not knowing that I had a short circuit somewhere in the Waffle Plates AC input - it’s a painless act, doesn’t even smell of...

We are still trying to repair Waffleplates, so someone who works at an automotive research institute here in Germany had another x-ray taken at the IFAM (Frauenhofer Institute for Manufacturing Technology and advanced Materials) which I’d like to share: We were so far successful in milling...

Oh, by the way: although everything is working as it should now I still have DTCs Dashboard/Meter #2: U1116 - invalid or missing data for electrical energy management, KOS CAN timeout / Not equipped BCM/ETACS #2: U1111 - invalid or missing data for primary ID Display CAN timeout / Not equipped...

Ok, I replaced capacitors C112 & C113 with round ceramic ones, each 1nF. Now the car is charging :shock: :D !!! Thanks for your immediate help Kenny, just brilliant! Yippee! Cheers, Joerg

Yes I got the board used and supposedly repaired, apparently someone had replaced the big cans with even larger ones (but same values), changed the 2.2myF capacitor in the AC pinput and snubber caps. As everything is soldered through the holes I suppose the Wafflelate™ had been removed as well

Sorry, just made the link public, you should be able to see it now. Seems strange to me, too that they blew, but there was a distinct small plume of smoke from exactly that location when I connected the charging cabel last time.

I found two broken capacitors on my (inop) lower board, C112 and C113. They are right by the 3 big cans next to connector L2A at J22. Does anyone know their values? They seem to have spit their guts out...any ideas on what might have caused that? Electrically they are between the bridge output...

Thank you! I measured 5V supply voltage on both sides of D301, so that’s checked. The relay itself checked out ok. So something in the AC sensing/relay control circuit isn’t working as expected. I might want to apply AC to the board on the bench and see whether the controller receives a signal...

Phew, thanks Kenny for pointing that out. All the other diode drops are good, so I’m hoping my waffle plate is ok. I’ll try to keep it short: I have a 2012 C-Zero that won’t charge but goes to ´Ready´ and drives normally. When I plug in the J1772, the EVSE connects it’s relay, the car relays...

Hi everyone and thanks to the main contributors of this thread for this incredible peace of reverse engineering. Sorry to bother you with another case of a failed OBC - mine keeps blowing the resistors without any other symptoms. After digging through all 103 pages I may have found a clue in...
