My Crown Vic was converted to 12 volt when I purchased it. The temp gage stay on hot. It has only one sending unit on driver side rear of block. Should I try a 56 sending unit?
After putting about 12 gallons or so in a m/t tank gauge pinned pass full and went out of sight. When m/t gauge show about 1/8 tank. Don’t see any drop voltage device connected to gauge. Do I need one or might problem be tank sending unit?
Clock was disconnected do you need drop voltage devise on it or is it able to work on 12 volts?
Is there other things I should look at?
