I have swapped my 3.3kw pdm with a 6.6 from AZEO. tested it. worked fine. then did a rookie mistake and accidantly conncted my HV heater to the A/C terminals but reversed polarity. since then it seems like precharge isn't happening. get 44v DC to DC code error on inverter. this is the report from the console:
and DTCs:
the f/s charger relay error codeis a code I carry over from before and I suspect it's related to my YAste Can Bridge comunication issue.
I can try and install my old 3.3 PDM and see if it's a PDM issue or a contactore or precharge resistor issue?
before PDM swap everything was working fine. just had this charger relay code that only affected regen braking. whats your thoughts? cheers

I have managed to fix everything but the regen braking. I'm considering getting rid of the can bridges and getting by MBS flushed with a dedicated firmware for yaste 62kwh. that should fix everything

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.

1990 Subaru Brumby EV Conversion

Vehicle
• 1990 Subaru Brumby
• Original Subaru manual gearbox retained
• Original dual-range 4WD retained
• Selectable 2WD / 4WD still functions exactly as factory
• High and low range both operational
• Clutch deleted

EV Drivetrain
• Nissan Leaf motor, inverter and charger
• Brat Industries adapter plate and spline coupler
• Resolve EV control system
• Tesla iBooster electric brake booster
• Hyundai i30 electric power steering

Battery System
• Originally converted using a Nissan Leaf battery pack
• Upgraded to a 63 kWh YASTE CATL LiFePO₄ battery
• Battery installed inside the original Leaf battery case
• Original Leaf BMS retained
• YASTE CAN bridge used to allow communication between the battery system and vehicle controls

Performance
• Approximately 80 kW power output
• Instant electric torque from 0 rpm
• 0–100 km/h measured at approximately 9 seconds
• Top speed not tested, but comfortably exceeds highway speeds

Range
• Estimated 300–400 km depending on driving conditions
• Highway speeds, towing and off-road use will reduce range

Off-Road Ability
• Original Subaru dual-range transmission retained
• Original selectable 4WD retained
• Low range still available
• Instant electric torque works exceptionally well off-road

Weight
• Current estimated vehicle weight around 1,285 kg
• Final certified weight still to be confirmed

Charging
• AC charging operational
• DC fast charging hardware installed
• Solar charging compatible

Current Issues
Like any custom EV conversion, there are still a few things being worked through.

• Regenerative braking is currently not functioning correctly
• CHAdeMO fast charging is currently not functioning correctly
• The cause may be related to either the Nissan PDM or the YASTE CAN bridge
• Investigation is ongoing and I'll post updates as I learn more

Conversion Cost
Approximately $30,000–35,000 AUD for the EV conversion itself, including battery, drivetrain components, engineering, fabrication and electrical systems.

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.
