No power lights etc but ignition turns over?

Has the wiring been hacked up? Or is it completely stock? And when you say it turns over you mean it cranks on the starter USING THE KEY right?

Are you saying the headlights don't work? If they don't, you MAY have a failed main splice under the dash. This is a big welded splice in the black ammeter wire a few inches from the ammeter.

you need to detail EXACTLY what does and does not have power

And THINK........was it over charging? (overvoltage) You may have burned out a bunch of lamps................

Thanks for the response.

The wiring has not been hacked up. It is stock for a '74 225 no a/c basic Gold Duster. Only the original radio was disconnected and a new one installed. But at the time, it was disconnected because it has an issue with a security feature of it. It's an old cassette tape deck.

Yes, it cranks on the starter using the key. That is correct.

The headlights do not work. No power to the headlights. No power to anything.

If it overcharged and burnt out lamps, would that happen while the car was on and running? Like, would it happen during the engine running?

It did not die. I had turned the engine off, parked. Came back, no power. No gauges work. Usually at least the alternator dashboard gauge will give a little wiggle and the gas gauge will raise showing the gas level.

Nothing was changed, it's been running fine for a few months. (was in winter storage prior)

I'll have a look at the black ammeter wire tomorrow.

thanks again
