The HV Junction box being prepared for installation (note the ISA shunt which will play an important role in conversions going forward)

What are the red isolators that are mounting the fuses? I'm looking for a solution to this at the moment .

Had a hell of a time finding these.

Great:D , ABS printing parts have not enough isolation ?

I found a variety of choices using the search terms "Buss Bar insulators". Here's a link to amazon.com https://www.amazon.com/LBY-Busbar-Insul ... B078TDD4X6

I like the High voltage junction box, do you have a part number for that?

It's a generic plastic box that was purchased from a local electronics store...

Why not try printing some and tell us how you get on

Google search : IP65 plastic enclosure

I like the ones with the clear lids

I will, but when I come to this part

Lots of wiring and component mounting done in the Bexus.

Is there a chance of you posting a schematic of how the high voltage junction box is wired.

That's awesome, many thanks. Some more digging and the best Google term seems to be "stand off insulator".

I've currently resorted to cutting out big chunks out of whatever my fuses were originally mounted to - these insulators are a much better solution!

It's funny how similar our projects have turned out - I'm also using a Tesla Gen3 charger in the same location, but I've gutted the end of it that has the supercharger PCB/contactors and am using that as the junction box for my 320V bus. I'm also using the TRW PAS pump, and it looks like the same vacuum pump.

Do you have more info on that (or pics)? That is a very good solution to make everthing appear OEM to evade the EMC testing when converting the car from ICE to EV with the authorities.

I have not published information on that yet. And now I feel that doing so may be a bad idea. I do not wish to publish Information which would be used explicitly to circumvent such testing.

However the procedure is as described. Remove the parts which you do not need and replace with those that you do.

It looks like Damien has kept his charger intact, so this discussion is not relevant in this thread.

Hm, that is indeed a good point. Thanks for the reply anyway

Top balancing the test battery today... here's the rear pack

The participants on next weeks course are building a HVJB for the Grey Goose project. It will be very similar to that used on BEXUS. I'll ask them to document the build and post details in that thread

Front of the car all back together. Next up wiring in the V2 VCU with Wifi and ISA Shunt interface.

V2 VCU and isa can shunt up and running in the bexus. VCU now controlling precharge, startup and shutdown as well as hv control during charging. WiFi interface works perfectly.

It may be possible to wire it up this way. Ive done it for other electronics transmissions in the past.

Weigh in for the GS450H transmission.

Oops, I'm waiting for the gearbox to be delivered, I need a crane to move it ...

Nice! Definitely great progress.

I heard you say "that's interesting" but couldn't make out what you were referring to. Everything working as expected so far?
