I have a 1965 Thunderbird that started and ran two days later I went out to start it and nothing happened lights, horn, inside lights all work but the nothing else does, any suggestions?

It sounds like the batty is dead. How old is the battery?

I used a battery I just bought cause the car didn't have a battery.

Have you tried jumping the battery?

I forgot to mention I did check all the fuses.

Yes I did but didn't make a difference.

Check your gound cable from your battery and recheck all your work that you did two days ago.

Jump the selinoid to see if engine cranks.

Check the cables at the starter itself. Mine had only 2 strands of cable connecting it. New cable and it starts fine

Did you check the selinoid at radiator support by battery?Also possible ignition switch burned out at start position.Remove ignition switch & check for continunity with test light.

Hello, I finally got my t bird running and going down the road. I have one more problem that I can't seem to find a solution to. According to the schematics the gauges have a common connection and that would be the constant voltage regulator located behind the speedometer. I replace it but still have the same problem of the temp, fuel and oil pressure gauges all read to the right when the ignitions so turned on. Any ideas of where I can look next?

It could be a bad ground for gauges.
