„ 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.
Re: L210 gearbox- ISA shunt or S-Box needed?

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?
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.
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?

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?)

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.

Happy Weekend all,
I used today public holiday to fit brand new resolver connectors to my GS300h transmission. In hopes to makes MG2 happy but still no change unfortunately.
MG1 only works
MG2 only only results in a piep sound from the inverter... aka something is not happy
Blending or selecting both MG1 & MG2 results in unhappy sounds without really being able to drive, it just appears to slip within the transmission.
What I have done so far:
- wiring check multiple time also with four eye principle
- New Resolver Plugs
- Transmission filled with 5L of Transmission fluid
- Tried higher voltages currently 85V
any idea how to get MG2 to communicate /spin up? Could this be linked to physical damage? I don't think so as then I would at least expect it to make some kind of motion sounds.
Looking forward to your thoughts.
Cheers, Marvin

Can you swap the phase wires iver and see if mg1 inverter can drive mg2 and vise versa? Or try the resolver plugs?

A success update:
So my main error was the gas pot wiring, yesterday during testing zombie sometimes spotted the error of Throttle12Diff. And indeed i miss interpreted the VW T6 Gas Poti pin out.
After some initial still unhappy movements I was then able to drive the van up and down the street. It maxes out around 30-40Km/h but i guess that is due to my amp limit. Also don‘t want to fry the thin testing HV wiring.
Oh so happy. I guess many small things but in the end it is always wiring.
Happy weekend and tinkering.

Is there an L210 conversion fully ready and driving out there? I still have one sitting in my shed, but this year will be the year I am going to convert one of my oldtimers
Edit: @chrskly seems to have one finished and running!

Yep. @andybpowell has it running in a Z3 (same thing mine is going in - hope to be wheels spinning in a few months), and Damien has one in his E36 - the Red Arrow.
Thank you so much Bobby, this will make fitting it to our 1973 toyota corona wagon much easier!

Can the 450h inverter run the l210?
I'm wanting to grab one of these for my 86 ev conversion, moving away from l110 which I had set up, it narrowly doesnt clear the front subframe .
Long story short:
- I have 450h inverter, and its wired in with VCU. It happily spins my l110.
- wrecker wants 1500 AUD for the is300 inverter, err no thanks.
- I want to be able to spin the l210.
I see that this question has been asked a few times, but found no definite answers. Has it been done?
And wanted to confirm:
Afaik the resolver plugs are pin for pin identical.
The phase plug on inverter side are not, but not a deal breaker.

Ended up picking up a L210 from an IS300h yesterday and plugged into the gs450h inverter.
Can confirm that gs450h inverter is plug and play with L210, although MG2 control feels a bit rough. heavy cogging when starting up, maybe resolver reference angles are slightly different as someone mentioned previously.

received a gen3 inverter from Japan recently and have been trying to spin my motor with it but am having some trouble.
When wired as usual, i get the rotor oscillating rapidly
Any ideas?
L210 is from an Australian is300h
the inverter is from an AWS210 crown hybrid - PN is G9200-30132 which is the same as whats on the wiki
And both Australia and Japan are RHD so dont think its this.
