no, ha ha, I luv it when people comment on things in the background, I do the same, I need to sell it to buy MORE electrical tape, if you are interested go to beginning of this thread and there are some pics of it, and message me privately pls

[Gregski]

guess what size we need?

so now waiting on material to arrive

[Gregski]

so I did a test where I connected a 300 watt (30 volt 10 amp) bench power supply directly to the inverter and the wheels spin just fine

more trouble shootin'

here I am bypassing the Positive Contactor in that black Safety Box and only closing the Negative one, and we see full voltage from the 30v bench power supply, so something is up with the Positive Contactor closing then opening, or maybe some circus board logic in that box, donno

[Gregski]

Finally, we figured out how to spin that transmission, and turns out it was operator error, I simply did not understand what the software was doing, once we figured it out, whalla

Impressive would be an understatement, Luke Star Walker would be, (will be proud)

just have to say after following your build since 10/21( I had to look back after my steering wheel comment a few posts ago ) and seeing that trans /motor spin ...WOW congrats lots of time patients and smarts in it

I just finished restoring mine to match the interior.....I wouldn't give up a gift from MOM for more electrical tape anyways.......

that looks amazing, did you have cracks to fill? and man I gotta watch what I say on them InterWebs, cause some people READ ha ha

Watched the video- congrats!!
Motion is exciting

I may have missed the the ingager modulater...Capt's log..VII.XV.MMXXIII...video of spinning tube. is it a Toggel switch, Lever or Laser pointer or just 3 buttons with arrows?...Move Ahead, Where you have already been and Park....Mid 1960' Dodge push button transmission 5 buttons and a lever.

you just made my day!!! it's a thingmajig

4 hours of unpinning and repining and all I got to show for it is the VCU and throttle pedal are now on the other side of the firewall

[Gregski]

needless to say it was a late, late night, but...

[Gregski]

got the second connector harness through the firewall and now the EV Vehicle Control Unit (aka VCU) as well as the skinny pedal live in the cab, getting ready for the next test from within the cockpit, the goal still being running and driving truck by the end of this month

FUN FACT: Let me put something in perspective for those of you remotely entertaining this idea, or thinking hewk no electric cars are too complicated, I have done a few LS Swaps, and I know for a matter of fact that this VCU has 40 pins total or 40 wires and the LS PCM has exactly precisely twice that much, 80 pins so 80 wires, think on that for a minute!

[Gregski]

if you've never installed a center console using the finest plumbing supplies, are you even a Certified ShadeTree Mechanic (CSTM) ?

console was sourced from a 2000 Chevy Z71, holy cow, I'm actually using a Chevy part ? lol

[Gregski]

then I added a seat for the driver, someday these will be recovered in black leather

[Gregski]

since our transmission came out of a hybrid [pronounced: "has a gasoline engine and an electric motor"] Lexus GS450h it actually has two transmission fluid pumps, on the inside it has a mechanical pump driven by the gasoline engine via the input shaft, on the outside it has a second electric one, that way when the engine is shut down at a red light lets say, the fluid still gets circulated

so last night I got the transmission external electric "oil" pump working for the first time, I was so relieved to hear it a pumpin' since up to this point I had no idea if it was good or not, and here's a little dirty secret, those pumps are worth more than the transmission

here's a little short video on BetaMax for you: Lexus GS450h Transmission Oil Pump Test

let's give it up for the OGs who will get that reference

[Gregski]

So the goal is still to have a running driving truck by the end of this month. So what do we have left to do to meet this specific goal?

1. Wire an Inverter relay to turn it on from the VCU
2. Add CAN Bus code to control the Chevy Volt DC-DC Converter
3. Wire a relay for the Toyota Prius EPAS (Electronic Power Assist Steering)
4. Wire a relay for the Tesla water pump
5. Add PWM code to control the Tesla water pump

This will be a crude drive test, most likely with a laptop sitting shot gun for S-box control as I am still in the process of finding suitable ChatGPT code in order to automate that.

Also we will be running an off board Chevy Volt battery charger, for this test lol

[Gregski]

well that escalated quickly, as I spun my wheels all evening chasing over a dozen grounds, I think I'm gonna list them all for prosperity if you see one I missed please let me know (also I think I will brand the apparatus cause details are good) may take me numerous updates to this post plus it's midnight

man this hydraulic crimper off of AMAZON sucks, it leaves these sharp edges that I have to spend more time filing off than crimping, do you guys and gals have a good one you can recommend please


wish I saw this review prior to buying it: The BEST lug crimper on Amazon! TEMCO vs. Generic Yellow Crimper

[Gregski]

so I am trying to reuse as much of the OEM stuff as possible for a couple reasons, one I bought it, two it's quality stuff, and when it comes to relays, there are dozens of different types and sizes and colors, so after a very lengthy and deliberate process, I decided to use the first two types I found, the big one I call the Power Relay and the small one I call the Logic Relay

the Power Relays can obviously handle more current, but in my mind they do work, for example they control a fan, or a pump, or a motor of some sorts, where as the Logic Relays just pretty much turn things off and on, they usually don't need any thicker wires on the load/high side they are just a switch too far for you to reach with your hand sort of speak

Progress Not Perfection

Alligator clips be gone, she's all hard wired now. Introducing the line up from left to right [on the fuse block]

1. VCU - working
2. Safety Box - working
3. Neutral Safety Switch- working
4. Water Pump - unplumed at the moment
5. Electric Power Steering, EPAS - working
6. Inverter - working (now turned on automagically by the VCU using that little relay)
7. DC-DC Converter - currently sitting on the work bench
8. Arduino UNO for PWM for the water pump - currently sitting on my desk waiting on a case
9. Idiot Light - working

* Oil Pump is fused and relayed in the motor compartment not in the cockpit
