450h inverter ohms?
After watching one of Damiens videos on the 450h wiring I check the ohms on the inverter wiring to mth,etc and got about 125 on all, which he said indicated bad wiring. I then checked the ohms at the inverter connector, and got the same readings, which would indicate the wiring is good. Does this indicate a bad inverter, or could this be normal? Thanks

Thanks for steering me there. I'm about to redo my wiring, so good to see wire sizes on that post. So, the 120 ohms is good if not connected to vcu, once connected should go down to 60?

Re: 450h inverter ohms?
It's a CAN bus, there's a 120 ohm termination resistor in the inverter, and your controller will have another within it, bringing the total resistance down to 60 ohms are required by the spec.
