Original gauge. Sender from Classic. Sender should read 30 Ohms at full? S#$% that ain't good. Will there be an issue with the voltage on the old gauge? I did the same conversion back in the day (1972) and don't recall ever worrying about the gauge. But who does at 22? Changed the Gen, regulator and lights. That was about all there was to it back then. Oh yeah a battery. No turn signals so no flashers. I did put a ballast resistor in line with the fan motor and was done. I will pull the sender out tomorrow. Just take the seat back off and undo the screws. Maybe I can reverse the sender to show 30 at full, maybe....There goes another day with this old truck
