Dead and backfiring

Alright guys I'm fairly new here and this is my first post got a problem gonna see if you guys had any ideas: so I took my 69 for a spin today whole drivetrain is fresh as of about 120 miles ago carb 582bbc/th400 anyway so I'm driving down the highway and start to notice the batt gauge going down finally it bottoms out and next thing I know the speedo starts to fade out then the tack and eventually everything I manage to get almost gone and the car starts wanting to die so I shift to first and 2800 rpm to limp back I let off the gas to turn into the driveway and it back fires hard and dies out Turn key absolutely no power no starter fuel pump or anything. I then wait about 10 min try the key again and heard the starter click I then turned the key off and left it sitting halfway into my shop before I started throwing sh it. Just got done fixing 5 other things and now this. What are y'all's thoughts?

Have your alternator tested.

X2 bad alternator, or loose battery connection. Had the same exact thing happen years ago on a 3rd gen camaro. Car should run off the alternator, but instead it slowly drains the battery until it is dead.

Re: Dead and backfiring

That's what I figured. But would that explain the back firing too?

Re: Dead and backfiring

Not enough juice to fire the plugs at the right time, so it backfires.

Re: Dead and backfiring

Did you solve your overheating problem? Was it the radiator?

And this too shall pass.

Re: Dead and backfiring

Sure enough the alternator was fried. Why would that happen. Do I need to put a regulator or something on this new one or was it just a defective unit y'all think? It's a one wire btw

Re: Dead and backfiring

Well I'm not a fan of one wire but sounds like the internal VR is confused or toast. Is it about 14 volts? Even though this document is against one wire systems also you might glean some helpful advice. http://www.madelectrical.com/electri...hreewire.shtml
