Definitely check the resistors. The ½Ω measurement is if you turn on the relay with a 4.5 V battery or 5 V power supply. To activate the relay, see small red and black circles: Negative on black, positive on red, obviously. The ribbon cable needs to be in place.

It's hard to say. That capacitor is across the mains input, so it seems unlikely to me that it would cause stops. The stops sound like an overheating issue to me. It seemed seemed to charge longer at lower power. I don't believe so. Those capacitors seem to have a hard life. Others have done...

Good point. The easiest way might be to open up the EVSE, find the place where the 1 kHz signal comes from, and replace it with a 555 timer or similar circuit, Or just get an adjustable EVSE from Ali Express.

It's most unlikely that anyone has a complete board spare. There is also another board with way more electronics on it under this one. Have you checked the small capacitors in the DC output section that often fail? To inspect the lower board, you need to disconnect a ribbon cable. Check the...

My understanding is that motors with permanent magnets are extremely difficult to work with unless you have special equipment. Replacing the magnets is unlikely to be practical, I think. I would also think that the motor controller firmware would have to be changed to take account of the...

Have you checked both upper and lower cavities? The HV charrger is above, the 12V charrger is below.

Extracted image: It seems we'd need a fairly simple circuit that powered up the pre-charge-via-resistor at power on, and turns it off one second or so later. If the other relay hasn't come on by then, it likely never will, so save the pre-charge resistors. It should be possible to design a...

No. There are hundreds of common resistor values. This one happens to be at the high resistance end. None of the resistors you mentioned is even 3% of the resistance required.

The back end of a battery chargers is a current controlled device, expecting to see a huge battery there to absorb the bursts of energy emitted. With no battery there, its voltage control will be expected to be very poor. So it may be that this is OK, though I'll admit it's a bad look. Elcon/TC...

But where to find these compatible 50 Ah cells?

I've attempted to fix many image URLs in my years as moderator of various forums (but not this one), and Google Drive has to be the least friendly for hosting images that you want to use on a forum like this. The URLs are ridiculously long (like kilobytes) and well hidden (though that's not...

Yes! That seems likely. Pins 1 and 3 are blank in the 2012, but 2 and 4 are blank in the 2010 (and presumably 2011). If this is the issue, then there isn't a trivially easy solution; you really need to move wires around in one of the sockets, Or wire up an adapter with plug and socket, but...

Yes. Some info in this post in the battery section. BMU: Battery Management Unit; it's a module under the back seat of the car. It talks to the CMUs (Cell Management Units, inside the battery) and the VCU (Vehicle Control Unit, I hope I got that last one right). Google them. My guess is...

Indeed. But any general purpose or switching transistor pair should work.

Ah, perhaps 401, with vestiges of underlines indicating which side is down. So 400 uH. I have no idea if you can get that value in that size. Edit: though 400 isn't an E12 value, 390 would be closest. And another nearby similarly sized inductor does look like it's marked 104. I guess 10mH may...

Alas, I don't have a good photo, and didn't have equipment to measure it. The least-worst photo I have is this: It looks to me that it says "107", but that makes no sense. I recall thinking it said "/01" (reading it the other way), but that makes no sense either. It might be 101, or 100 μH...

Ok, thanks. It seems that red and green are not correlated with LEV50 and LEV50N then.

It could make some sense if there was a resistive divider, and the 8-cell boards worked on 8 cells worth of voltage. But this part of the red board circuit seems to be working on only 4 cells worth of voltage. Just in case, I plugged in an extender board (the board for cells E-H). It's a...
