Question type: Maintenance & Repair

I have a 66 beetle that was running ok until it didn't
want to start, if I jump start the car it works fine but
as soon as I turn it off its dead, I tried the battery
but it's charged
So I turn the car on and when I take one of the
battery cables it dies, any advise

The alternator is bad, on older cars if you get it cranked and take the negative battery terminal off it will run if alternator is good and die if its not good.

Battery is also on its way to being replaced soon otherwise it would run until drained. and as far as cranking power goes anything under 12.4 is a bad or drained battery it needs to be 12.9

Please read this, are you sure that you have a 12 volt system? Maybe someone changed it, this car PRETTY OLD! Here's the article, http://chircoestore.com/tech_articles/?p=98

I think these cars had generators, unless someone upgraded it?

Yes a Gen, it still has to produce the voltage needed to run the electrical if the battery can't hold a charge. Same either way.

Alternators are more efficient, read this article below, http://www.differencebetween.net/object/difference-between- alternator-and-generator/

They don't use generators in modern cars...
