Yes i have a HV wires with connectors and LV wire loom that is still joined with some other wires. LV wires jolin to large multi pin connector. I gather this goes to A/C auto amplifier.
I would like to try the compressor operation on my car battery 380Vdc but i dont know the correct UART sequence for starting and then signal for rpm setting.
When evaporator air is at 0°C compressor should stop and when temperature rises to 4°C it will start again. It should be simple integrating this with in car A/C relay. I just have to know
1. start command
2. stop command
3. maybe 2 or 3 RPM settings between 50% and 80% of compressor speed
If anyone can record signals from a working LEAF compressor i could then try to interpret and setup my micro controller to clone those signals.
There are still Tx Rx lines, that means inverter wants to put out something. I have to check if this is just reporting or it needs any response to work...
