Brilliant!
Success
That's good news

All connected up as in the schematic except I have the inverter switched 12v powered via the ign instead of OP3 and relay.
I suspect Damien is not using the OP3 output. When he's less busy i'll ask him.

The question you had about OP1 and negative contactor during operation looks to stay closed. It does raise the question of the precharge contactor though and if it releases again or remains closed or does it matter.
It's not unusual to drive both the Negative and Precharge contactors with the same control signal. The precharge resistor is irrelevant once the Positive contactor switches.

Not receiving any Pack Voltage, Current or Power, just RPM and the motor and inverter temps but that should all be sorted hopefully when I get the ISA shunt in. But that's for another day
That's to be expected from the software;
Serial2.print("v");//dc bus voltage
Serial2.print(Sensor.Voltage);//voltage derived from ISA shunt
Serial2.print(",i");//dc current
Serial2.print(Sensor.Amperes);//current derived from ISA shunt
Serial2.print(",p");//total motor power
Serial2.print(Sensor.KW);//Power value derived from ISA Shunt
Serial2.print(",m");//motor rpm
Serial2.print(inverter_status.speed);
Serial2.print(",o");//motor temp
Serial2.print(inverter_status.motor_temperature);
Serial2.print(",r");//inverter temp
Serial2.print(inverter_status.inverter_temperature);
Serial2.print("*");// end of data indicator

Thanks again Kevin. Has helped to get another bit further down the line for my own build as well as James' project Figleaf
No problem, well done for sticking with it... all I ask is that in future you and James update the wiki so that people can help themselves
