Hi all,
Does anyone have the excel spread sheet for adjusting and calculating the voltages/resistors for the rotary switch i seem to have lost mine.
Thanks
I'm not aware of the excel spreadsheet you're referencing. These are a very simple voltage divider though. As long as you know what the individual resistor values (which should be identical), the calculation is covered on this link - https://www.allaboutcircuits.com/tools/voltage-divider-calculator/
Most ECUs can read the raw voltage as well, so actually calculating this is usually not required.
