Will a 24 v fuel gauge read on a 12 volt feed? I guess what I'm asking does it measure resistance so would it measure half full? I'm changing from 24 V system to 12 volt and fuel gauge is 24 volt I'm hoping I just need to change it and not sending unit in tank. Any comments?? Bob-------- Explanation:: other than a few gauges I find myself no longer in need of the 24 volt side of the system. I no longer have the big 24 volt ac system or 24 volt starter, defroster motors or windshield wiper motors. All lights are 12 volt. I could retain the 24volt system or just replace a few items and simplify everything by making all 12 volt. Bob
