I have a 1995 Range Rover HSE, - the resistive steering wheel buttons are grounded.
If I connect a multimeter to earth and HU, I get different ohm readings when I push different buttons. When I connect the multimeter to "+" and HU I get the same 12V reading no matter which button I press on HU???
I should be getting different voltage readings?
Am I doing something wrong?
Can fusion brain (analogue inputs) detect different resistances, or does it need to see changes in voltage?
Any help would be greatly appreciated
thanks and confused
Peter
