74 Ford 5000 D instrument panel

[ed1]

My 5000 D instrument panel fuel gage and and temp gage quit working. I checked ground and it is good. Tractor is original and I would like to keep it that way. Possibly the voltage regulator? Any thoughts would be appreciated.
Thanks,

Where did you check ground? Both of those gauges get their ground out at the sender, The ground on the instrument cluster is just for the panel illumination lights. Do the oil pressure and charge warning lights still work? If so, then it is likely the voltage stabilizer. If not, it is likely the 5 amp fuse in the wiring behind the the cluster above the fuel tank.
