Re: 4WD Rear Wheel Torque Display
The current or voltage from the current sensor used will be too low to power a meter directly so doing something like that would need a purpose built low-level DC current meter.
The current may also not be constant but pulsed which is not always picked up by a DC current meter and incorrectly displayed by an AC current meter.

Re: 4WD Rear Wheel Torque Display
Then you need to find a current sensor toroid that gives a voltage output compatable with the meter you are using

Re: 4WD Rear Wheel Torque Display
No you need a DC sensing coil

Re: 4WD Rear Wheel Torque Display
Thank you Domen,
The main thing to determine is if the QashQai has a signal wire to a rear electronic coupling for the 4wd or if it is a full-time all-wheel drive system.
If it has the solenoid to vary the amount of torque distributed to the rear wheels then the only other things to determine are where this wire is located and how many Amps current turns it on completely to full rear-wheel torque.
The circuit is designed to uninvasively clip over this current wire and if calibrated correctly for the correct value will work just the same as in out Xtrails.
