Yes electric only! The goal is to now have this as a main EV battery, we are going to use this as a test bench for various researchers.

We also have this battery in house and we could at least get the car started, we aim to put in a more suitable battery down the line, but just want to see if ...

Hi all,
I am currently looking into battery ideas for a conversion I am working on, currently have it working on the bench, Gs450h transmission and inverter, with the Zombieverter, all wiring complete including pre-charge. The person in charge of this conversion (my boss) owns the Gs450h and is ...

Ok great news,

It is now working, it was in fact just the relay, seems to be running relatively smooth, still need to get a permanent lock for the input shaft done, I have the spline out from the clutch and will weld shortly. I will also redo some of the wiring to make sure all is safe.

I now want ...

Ok, I will get a relay sorted and try from there, that was my next guess for getting it working.

Don't know how I forgot to flick it on when I sent those spot values, Once I have the relay in I will re send it all. Would the relay be enough itself to not get it into proper operating mode?

Ok so I have placed some photos of the low voltage wiring, bit of a mess at the moment but yes I did follow the wiring with the Gs450h and zombie from the start, there is a few parts of it i'm aware are missing, for example - B and B+ from inverter are not connected via a relay at the moment, they ...

So I have grounded the inverter now properly, just giving an outline of the setup, not ideal at the moment, using two supplies to get up to 60V, but now still nothing from the inverter, and not even a current draw from the supplies. Is there a common issue where this can happen? I have attached my ...

Perfect, I will get on that, I think I have a few simple things to look over before I go wasting anyone's time.

Looking through the forums and things like grounding the inverter casing I glossed over: Ground the case to the same controller ground or from the other "HV" PSU?

Will tidy the rest and ...

I know have 61V of supply but I still have some issues.

So I have my prechrage resistor and and manually switching after precharge is complete. I am still yet to hear any inverter wine, my communication from it seems to be inconsistent, some times when I am testing, on the web interface I get ...

Yup was the exact same problem with the startup when initializing the shunt.
That is all working now, just need a precharge resistor now and then test run the full setup, not sure if the 30V @5amp will be enough to get the inverter operational.

Thank you again

The Shunt needs to measure it.

You can always manually precharge with a resistor. Zombie wont know it has not done the precharge itself, it will skip through it if the voltages UDC and UDC2 are matching.

I do not know at what voltage the Lexus inverter will work.


Hi again,

Back now finally ...

I think I actually just confused myself upon further reading. So yes I am interested in doing some more unique setups going forward but I just now want a basic operational unit.
Instead of all the complicated stuff I was mentioning with the switches I have now realised and am guessing that you just ...

I understand that is a normal selector, I am looking right at it lol. Just questioning the integration of the solenoid wiring with the zombie wiring, not how a gear selector works.

Unsure yet of how I would like to integrate into the dash and do unique parts with it but i'm sure it will come up soon.

I have gotten the ISA Shunt since then, (although I didn't realize it doesn't come with connecters - lesson learned), and will be ready to go very soon.
One question - one the Lexus Gs450h transmission the gear selector solenoid, do you also wire this to your +12V switch which indicates to the ...

And does that just have to be measured across the high voltage + and -. For these initial test at around 30V will a fully functioning precharging setup be needed? I know on the older Gs450h VCU that wasn't the case but with the Zombieverter is that needed or only a UDC value for it to read.

Hi all,

I have just recently began a project using the Gs450h inverter and drivetrain to hopefully complete a full conversion of a 1997 Jag Xk8 as my 6 month work placement in University. I am at the stage where I have now just received the inverter, transmission, oil pump & controller and entire ...
