Re: EV Conversion using prius gen 2 inverter/transaxle

just to confirm. The IC6 is the one circled on the picture attached.

Ehn, don't take it from me, but the label says IC6, so, sounds good.

If yes. Please indicate for me pins 4,5 and 6.

I had a feeling when Johannes gave that instruction that it wasn't foolproof enough.

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

I believe on the Gen 3s the weight was 289 lbs and 40lbs for the inverter. Just for comparison's sake.

There is a place in the openinverter interface, near the top, to type in manual commands (and then hit enter). This is an alternative way to changing parameters or starting and stopping the inverter.

Re: EV Conversion using prius gen 2 inverter/transaxle

At this point in my diagnosis, I think people had me check the input of the actual power transistors themselves (the output of the MCU), to see if they were firing. But, I'm not familiar enough with Johannes' design to do that. And that would be odd.

One of the only things I can think of is that ...

I'd get a small trailer for the Prius and run it as is. It's just hardware store runs.

Any vehicle will be equivalent. Which one you choose should be the one you're most excited to work on.

Gen 2 Prius is okay, but a bit wimpy with the current setup and Johannes probably won't develop it further ...

Re: EV Conversion using prius gen 2 inverter/transaxle

It 100% will not work if you have not connected MSDN to 12V+.

Also there's MFIV on pin 27 (coincidentally, on both boards). That's Motor Inverter Fail, it has to be connected properly or it won't work.

I don't think that one is on the procedure, but it's in the diagram.

Zapheap? That's some fantastic branding.

The success of this will depend on how well it's marketed. It's an odd thing to crowdfund, because you're not getting anything out of it.

I hope it's successful. I could watch that kind of content all day long and it's been 20 years since anyone's done it.

It sure is discouraging to see:
