The only reason for the fuse to blow that I can think of is that I placed CMU on th cell tray in the opposite direction and cell taps touched cell terminals. @MickeyS70 It's not exactly same. "Cn" and "Sn" pins are leading to different cells. That's extremely important when checking continuity...

Be wary this is a single 4 cell CMU. Notice the lack of socket for the cable for the other slave cmu. Pinout of LTC is different for 8 way CMU. Not c1 but let's say c5. Anyway it turned out to be a single blown smd fuse between cells with faulty reading. Yay easy fix 😊 Tank you guys for...

Thank you for fast help. https://myimiev.com/forum/viewtopic.php?t=4866&start=10 I hope it is not this thread. Pictures are gone. I charged 12v battery before checking car for the SECOND time. So that's not it. Here's pdf with a description of LTC chip...

I have read the other thread with 11pages but still don't get it. Can I just swap LTC chip? Analog.com have pinout of the chip. Is it possible to check voltages on its pins from cells? That way I could check if there's a fault between voltage tap and LTC chip. If LTC chip swap fails then I...

Thanks mate. For future reference, here's the sia47's post about OBC charging power being locked to 6kw power. Also I forgot about 20A HV fuse in there. That would limit charging power too. Update - I have found thread about FFE chademo but there are no details that would interest me. I'm...

Hey hey people ☺️ Tesla's OBC is easy to boot, but I have to adjust current draw according to the messages sent from the car to its original OBC. If chademo charger receives messages from the car to lower power down to 6kW or even less then I'm sure the OBC receives such messages too. I don't...
