Okeydokey, here we go, mo' progress. I'll try to go in some sorta' order but, you know, stuff... Also, try to remember, everything we do here, has to have a production run purpose to it. What does that mean? Nothing can be one-off. Everything has to easily and technically be repeatable and not...

Progress, obviously... (you might need to squint, but progress is there, somewhere, probably under that thing on the left...) Working on wiring. You get all these harnesses and you have to make connector decisions based on where the source of the wire is and where the final destination of the...

Alright, so where I am in this build is here, working on the Tech Box, here it is. If you go back a couple pages, I put a basic diagram of the Interconnects (this usually refers to moving power, DC mostly, from point A to point B.). This box will have the bulk of the LV (Low Voltage) wiring in...

Bus Bar pictures - all from the Tech Box. Custom bent bus bars Looking down into the Tech Box Another view, more completed in this pic. Alright, back to work, that C110 won't bend itself! - Patrick

Haha - I was just saying that! It's an interesting idea. - Patrick

Yes, that is also interesting but, I think less OEMy - you have to basically stop to shift, if I read this correctly. BUT, absolutely worth the effort to call Advanced Adapters when this build is done. Very interesting. Maybe, I wonder if you'd have to stop to shift if we did the same thing...

I'm working on this part of the Tech Box: I need to get the Power IN to the Tech Box to branch off to +B and -B on the Inverter. If you scroll back up, I put a diagram showing the layout. Here's the parts that make up most of that, graphic view to see what I'm working on: - Patrick

Yeah, maybe that. Interesting. I don't think it's synchronous though. Whatever, interesting idea. - Patrick

It's a legendary transmission, to be sure but, once again, it's still a hydrostatic component, albeit a geared flavor. The thing that keeps it going is to have some form of hydraulic pressure and that's not a thing in the EV world. If you start from the ICE propositions that the motor is always...

Please, I've tried everything to figure out how to maintain the drivetrain in an automatic transmission set up. The state of art right now is a TorqueTrends 1.9:1 reduction unit that sits between the Dana Motor and the NP231 TC. The Austrians make a similar version that's being used for F-150...

...and, I don't like to cut or touch ANY stock parts, especially the firewall.

Super quick, thought you builders and makers would appreciate the jirations I'm going through to fit stuff in. Here's a quick snap of the major components and the Tech Box. Here's the Tech Box: It sits right next to the Front Battery Box and needs to contain: - Inverter - BMS (Battery...

Hay Mac, I think you nailed one of our biggest design imperatives: EVERYTHING MUST BE SERVICEABLE by the Owner. 217:1 - that's the ratio of a typical ICE set up of moving parts to a typical EV vehicle engine bay. AND one of the ways to make it as inexpensive as robotically possible is to drop...

100% agree, please, find a hill and scream that in all directions. Quoting @GATORB8 "Regardless, I'm in for all the options possible, because a Jeep can have a different meaning to each of us.". (bold and ital added by me) - Patrick

No, it doesn't work that way, well, no, not at this level, and not for any practical use, no. It's complicated but, no. - Patrick
