There's people on here who have used them as low as 78s... But basically 72-92s holds true for most stuff gs450h or most inverters we use (108s in more trouble than it's worth as you have to be selective with chargers)

That will do it a partial insulator (or whatever that is) in contact with an HV terminal wall cause isolation resistance to plumit

If I unplug the HV connector on left side, I get 1500MΩ reading. That cable runs directly to the LS600H inverter. When plugged in, reading drops to 15MΩ and I can toggle it back to 1500MΩ by disconnecting the voltage sense wire from ISA shunt. I have tried changing shunts, disconnected pre-charge ...

Just checking the obvious...when you say inverter disconnected HV is live? (Otherwise your just measuring the wire to the contactor). I went with 1000v for isolation test because insulators start to break down at that voltage (plastic conduit becomes noticeably more conductive at 1000v !! Probably ...

She is MOT'd so now road legal ...now off to tax it as petrol so I can actually use it.... Then off to declare war on DVLA

'I just bought a 4th Gen Lexus GS450h Powertrain. - Now What?'

Has no one suggested a 5th?

Buy a whole gs450h either early one i.e. the one that your never quite sure if it's ugly orthe later style one that just looks like everything else... Ditch the engine put bi battery in it and you can ditch ...

here my take on the situation....

i would say with 95% confidence is that we are dealing with old car parts here, we don't know why the cars were scrapped and there's a high likelihood many of these motors/gearbox things have done high mileages and have not had fluid changes and probably on their ...

Surely a zafira pump fills the requirement?

i'm now now getting close to road worthy with my project is about time to think about phase II ...
My plan for phase 2 is to mate an is300h transmission to to a mazda, initial you would think easy ...however mazda use an aluminium frame (PPF) to link the rear diff to the transmission ... in the US ...

It might be worth tieing the torque frame to the transmission instead of the floor? You have rubber mounting on the diff then solid? Mounted the torque frame to the floor. That turns the floor into a speaker.
tieing the PPF (torque frame) into tranmissin is quite significant job ... just googling ...

I started testing the new batch today and indeed it seems like not all modules are created equal. I have two that work perfectly and two that display quirky values on certain channels. Will look further into it but it seems there is a quality issue, probably with the transistors.


have you used ...

you might want to watch some bobbycomelately's interview videos for some reference/ideas
hope that helps

this problem would also probably made worse by the esp8266? although its obsoleted by the lillgo tcan now.

Passat batteries are 12s so 12*4.2= 50.4v (only use 4.1 max) ... Biggest problem of this will be finding a charger (other than ebike charger) that's happy with the 35v(2.9v) minimum.

Ps have you spoken to janosch foxev.io as he has actually put taxis though and iva with leaf cells and motor.

But ...

Nose job time Payday went to soon

3.72 => 4.11

Have you brought shares in a tire company?

Isn't the gs450h Torquay enough for the Chevy?

Don't most people go the other way to get more speed at lower rpm?
You seem to want to turn the Chevy into a very quick accelerating projectile

Keith Mitchell is able to quote on EV conversation again
Just got a significantly cheaper deal with them over Adrian flux

Looks like I might be investing in a long steel bar to do some experiments

1) The control signal is negative
2) no, I have not found how to use desat
3) I connect the resolver to the johu board
4) high voltage is one wire, it can be seen in the photo (connected to the yellow wire) and it is signed by me on the diagram.


Hi just want to clarify point (2)... As I'm aware ...

after a long absence of shame (will post update, when i have energy....) i finally got movement

I think it is a very typical example of handing over a converted vehicle. Even small problems that take like 30 minutes to fix will make some people write off an otherwise perfectly working car.

I don't think that's even limited to an ev conversion .... anything non standard or old would throw ...

The battery box was a memorable hack job, even DIY standards.
The boxter converted by boxterev is probably one to copy except cutting out the boot floor for the battery box, that is a big no no by DVLA in UK at the moment.

On the outlander obc/dcdc there is a 12v input to enable the dcdc, however you don't want this on during precharge otherwise it will try and draw current to run the dcdc (alternator), the easiest way to achieve this is so run a relay on the high contactor output of zombie (yes the outputs still work ...

Ha!! Works on the bench then in the car....not a chance unless your tom de Brees or some other wiring god!!
I would advise everything being on a permanent live initially then slowly move things to switched after (except dcdc enabled otherwise you'll blow your pre charge relay) ... I had to rip out ...

I have posted the entire Q&A most sections i dont think its appropriate that we should comment however anyone chip in if they think differently
