I am new to this forum and recently purchased a 1972 Challenger Rallye. Car has been running great up until this past week end. Went to start the car and got a rappid clicking noise, which I assume is my starter. Did this once or twice and then started. Drove it for the majority of the day, parked it and the following morning it was dead...no clicking or engine turn. Lights on the car worked, but decided to change the battery any way as it was from what I can tell over 5yrs old. Put in the new battery and now I have nothing not even headlights? Any thoughts on where I should start to diagnose the problem? Could this be solely a starter related issue, ignition switch issue....I am at a loss?

Thanks for your thoughts! Joe

Just off the top I'd look at the starter. There is a starter box just off the battery. You will see the wires run from the battery to the box. I have crossed the poles on this box before and started the car from it. So it might be bad. But it sounds like one of these. I hope this helps.

voltage regulator. Cheap easy fix, known for failure, fails to allow alternator to charge battery. Car will run on battery alone for a while (longer with no lights or accessories on) and then suddenly...nothing..no juice in battery because it was not being charged.
this was my problem on my 1970 Challeneger.

I found a mobile mechanic. He had a tester that hooked up to alterantor and battery for diagnostics. Step one was taking alternator to parts store to test...that was good, so voltage regulator was next. never a problem after.

You might also want to check if any fusable links went out. When my 68 charger's alternator blew, I had to replace that, then voltage regulator went and that fianlly caused a couple fusable links to go bad. So I think all the above replys are things to check for
