Good question "should I have power on both sides of my key switch when in the on position "
YES both sides of a good key switch should have power when ON, but when OFF ONLY the BAT INPUT side has power. Then when switched ON the output also has power, that's the switches job to switch power to the output when ON....
NOTE The answer assumes youre measuring at the BAT INPUT side of a key switch that is properly connected to battery voltage source while you then measure at an OUTPUT such as IGNITION OUTPUT if its an ignition switch turned ON
If theres no power when ON the switch may be bad or theres a problem such as a short on the output circuit
An ohmmeter can also be used to measure continuity and resistance (should be near zero ohms ) when On from INPUT to OUTPUT

I’d probably plowed about 3000 acres (in my head anyway) by the time they found me. This is where my love for tractors started and has only gotten worse in my tender 50 yrs on this “green planet”.
