Yes correct. And that is how I have it connected.

I was referring to this section in the wiki. https://openinverter.org/wiki/Lexus_GS450h_Drivetrain

„ If you combine a LHD transmission with a RHD inverter (or vice versa) you might end up with a motor that is juddering, not spinning. IN this case you need to swap any two phase cables of both MG1 and MG2.“

I will need to ask someone to get some photos as i am not close to the workshop right now. But let’s imagine i wired everything up as intended. At least that is what i tried to do.

In software i am in run mode & drive selected. Inverter Status is On. Throttle is calibrated with pot min & Max

I applied 87V DC via somw battery modules which are connected via the SBox which to my delight was easy to integrate and an audible contactor closing is happing when start is pressed.

Ground is conneced on the inveter. Motor ground might need ro be improved. (Is that a common issue)

Lastly the little black cable and plug seen in the front right of your photo andy. Is that to be connected or is ghat for the buck controller? I cannot find any infos on it. Nor see it connected in any videos.

Thanks for the swift help.

spare black cable is for dc-dc not used in my case

Hi there, @toxakartoxa
i have an inverter board from a toyota camry 2012-2017 with the number G9200-33171 similar to the crown one

do you know which IC is for REQ CLK HTM MTH ?

thanks in advance

So I had spend some more time trouble shooting but unfortunately the inverter is still unimpressed by my skills.

I have wired it up as shown in my drawing. Can someone find a fault? My issue is that when I have the 12v positive and GND connected as shown then it blows the 5amp fuse to the relay. The relay is supplying 12V+ to the inverter. If I switch them around then at least the fuse does not blow.

For clarity reasons the plugs are facing me with the "plugging side" if that makes sense.

I also attached the parameters used in the Zombie.

Thanks in advance for the support.

The one thing not in your wiring diagram.

The back of my wired connector. Note I have left out one of the resolvers as this was for a test setup for Zombie testing.

Connector pinouts usually correspond to backs (wire sides) of connectors and so does most numbering.

Thanks Tom for the fast reply. Yes will certainly extend the diagram. But happy you agree so far.
Your wiring looks like mine so it must be something outside of the plug. Alright will try more ideas. Thanks for the support.

Hi together,

now where I finally got my L210 running with Toms help. I have one particular issue. It appears as if the Motors are slipping. Is this a case of Oil missing in the transmission? I tried with half a litre of ATF but it just spits it out with a lot of pressure? Is this a common issue? How much Oil is required ? Found something around 4L. It works best when only using MG2 but it still grinds. Input shaft is locked. All other components have no play and don't cause noises.

Does someone know the Oil pressure of the system so I can design an adequate cooling loop?

Thanks for the help.

Marvin

To fill these, you put oil in the fill port until it starts to overflow. Then close it up and you're done.

Hi all,

I have a L210 with matching inverter sitting on the bench and want to get it to spin. This transmission will likely not make it into a car any time soon, but I want to assure that it's basically working.
I saw in @andypbowell 's video that you can get it to spin with a 60V power supply: viewtopic.php?p=62386#p62386

I have everything wired up, but now I realize that additionally I need either an ISA shunt or a BMW S-Box / VW E-Box? Is this correct?
Both Andy's and Damien's Video about the GS450/300 H do not mention this so I am unsure.

What would be the easiest (cheapest) configuration to get it to spin? Is saw that an ISA shunt is about 375 €, used S-Boxes go for half the price.
Is the effort to integrate similar?

thank you

Hi Tom, is it required to connect all four pins of the voltage supply (+B and +B2)?
I think I saw in Damien's GS450 / 300H video that he connected only +B2 and GND2.

I wired both, but did not measure the inverter to see if the pins are joined. If the pins are joined you can get away with just using one of each.

Hi all,

in todays testing session I switched inverters again but nicely no change but that also mean I am still struggling to get MG2 to behave. I press the accelerator it just rumbles violently (setting MG2 only). If I run MG1 only I can drive slowly in the driveway but it still sometimes give the feeling of slipping gears.

I tested the connection from Inverter to Resolvers for continuity and all are fine. + used some contact spray in some hopes but as expected no change.

Also we tried changing the phases of MG2 but that also did not change anything, so back to OEM.

Any ideas of what I should test next? Could the input shaft locking cause any of this. I am so confused why MG1 works fine but MG2 not at all. Basically the inverter gives an error beep if you keep the accelerator pressed. And then does nothing. But if you tap it the initially it is loud and vibrating strongly.

Best Marvin

Wondering about suitabilty of the L210 for an application requiring max about 10-15kw of power, and apologies if this is a stupid question.

I've seen reports of others spinning the L210 at very low voltages, so is it possible/safe to use 48v to the L210, and can the zombieverter limit max power output (using potmax eg) to 10-15kw, thereby limiting the amps?

If it is possible could this set up run for any length of time to make it useable?

Posted: **Sun Jun 08, 2025 8:45 am**

They have been spun on the bench with 60V but it's not clear at what power output. For those power levels you could probably use something a lot smaller and better optimised (HSG maybe?)

Posted: **Mon Jun 09, 2025 2:48 pm**

Yep, that's way overkill unless weight is not an issue. Look at what motorbike conversion use. If you want to stick with OEM reverse engineering, viewtopic.php?p=64424 is another option.
