Why 10.7 volt input at ‘71 Duster instrument panel?

Also - with the engine running - the voltage at the instrument cluster plug is over 13 V. I also found another pin for dash lights that reads 11.9 V with the engine running. Maybe I’m ok with the voltage issue. I didn’t run the engine earlier because I was in the garage and had a gas leak at the carb check valve that I’ve since fixed.
