Hi , @matthewjstead @KoduEV @isak . I have installed the 62kwh Yaste kit with the Yaste CAN bridge. It works but I have an issue with the Chademo charging and regen since the upgrade. I suspect it may be a communication issue between CAN bridge and resolve EV but can't rule out a hardware issue with the OBC. I also have an issue with charging not stopping autumatically at 100% but no problem with the 85%. other then that it's fine. we be happy to hear if any one has any ideas how to Diagnose those issues and fix them? that would help a whole lot of potential resolve EV users that would like a battery upgrade.

Why Convert It? The goal wasn't to build the fastest EV. The goal was to keep everything that makes a Brumby a Brumby—dual-range gearbox, selectable 4WD and practicality—while giving it modern EV reliability, performance and range. It's still very much a development project, but it's now a fully drivable electric Brumby that retains the character and capability of the original vehicle.

Since April 8th it's back to the road! [image: 1780514460331-img-20260408-wa0001-resized.png] Everything works fine. It drives great. And I have to say thanks to Isak for the great resolve EV conversion kit! With the 40kWh battery pack the range is about 200-250km when driving in the city.

Sick mercedes. I love a good wagon. Best of luck with the conversion!

+1 on this. Cruise control integration would be awesome.

As the little suggests i have a intermittent fault with my resolve oled screen. I've gone through everything a good few times to diagnose it, but cant figure it out. Sometimes the splash screen comes up and it works fine, sometimes nothing. I cant predict it or do anything to cause the fault. Its pure luck as to when it chooses to work. All 4 wires are connected and wired correctly. 2 can wires, 1 negative and 1 live from the resolve ECU. When its working and not working all wiring, continuity and voltage remains correct. Im not using any none-leaf none-resolve can components. Just the Resolve ecu, oled and then leaf bms, inverter, pdm etc. Has anyone experienced this and have you found a solution? @isak

Finally got the wheels turning, LeafSpy connected for long enough to do some DTC fault finding. Errors reported as expected when disconnecting different parts of the system, only when the inverter was disconnected no change in DTC. So I checked the inverter connector for continuity and there was a wire break on the ground. Nice easy solution despite lots of investigation. Time to find space for the batteries.

Something to investigate - the version of OS on your device. This occurred to me before but I thought I’d covered it because I’ve always used 2 different devices iphone and iPad. iPhone is 26.4.2. iPad is 18.7.9. Since they were different but both failed to connect I put aside that idea. But this morning I dug out an old smashed screen iPhone running 15.8.4 and it connected first time after I turned Bluetooth off / on. A couple more tries and still worked. This is not a comprehensive proof of anything. It might just be lucky coincidence. I’m out for a while now, but if it regularly connects when I get back home for more testing, it’s the start of identifying the root cause.

Hi Everyone, I have a 30ft classic launch which until now has run on diesel, I am pulling that out and repowering with a Nissan Leaf system, and 62kWh battery, and using the Resolve Marine Controller and Wiring Loom. Has anyone done a similar conversion anywhere? I am really struggling to find someone who has done it before, certainly not here in NZ. Look forward to hearing from anyone, regards, Di

Thanks! The batteries are modules from 24kwh pack. Purchased both as-is from another ev conversion builder who had already reformed the modules into what I am calling two sets that you see in my pictures. For each set I have a large set bms bus bar orange thing. To make this work I had to do some rewiring of the bms harness which involved re-pinning the connectors. I was able to locate and find connectors (Mouser) similar to what nissan used in the original bms harness. I purchased the little pins (both male and female) along with a crimper. Now the bms control module sees the same modules as it did when the configuration of modules came out of the pack. My next work is to create an "extension cord" that will allow both battery sets to lie end-to-end like you see in the photo. I have pinout diagram I drew that might help anyone that wants to do same thing I can share if interested and/or can put up photos.

@isak, I have a 52 second video of the GE Jeep maiden voyage I'd like to post (16.5MB). Is this possible?

Now I have to get a 3D printer...

Holy crap that is cool, well done and fun!!!

@isak - another week goes by. Please advise on status of replacement display.

In the later stacks the logic for Chademo was moved from the pdm to the cars vcu so it won't work

@isak please could you advise any extra steps I could try like clearing/manual resetting the microcontroller to enable connection, or if any of the configuration solder links might affect connection? Alternatively I have access to an electronics lab if you could guide me through firmware update using JTAG/Atmel studio if this is an option. My soldering should be good enough if this is possible. I would also be happy to trade my controller in for a micro-usb or usb-c model. Thank you

Very nice!

I am not sure if the compressor has HVB+ and HVB- going to it all the time. or if it has some contactors in the PDM that turn on with LIN control as well. have to pull the PDM open and see... I do know that the PTC heater has HVB+ and HVB- whenever the Main contactors are closed. so probably the same with the A/C compressor.

This is what came with my purchase, I have no idea what this little plastic piece is for.

Are you using the Resolve plug and play wiring harness? I am and I can't get my motor to spin, getting a 206 error code I can't "Resolve". What are your thoughts?
