Correct.  Cars with solid state components need that battery to be connected all the time.  It acts like a big condenser, smoothing out a lot of electrical 'noise'.

So its okay if the car dies when the battery is disconnected?

Is the alternator charging the battery ok?  If so, there is no problem

If what you mean is the car quits running when you disconnect the battery-good. A lot of modern electronics don't like running off an alternator without the dampening effect of the battery on the output. It's possible to wire the car run directly off the alternator. Don't ask how I know.

The 292 in my '58 Custom 300 dies when I remove the battery. I thought maybe the alternator was bad, had it checked and its fine. I replaced my voltage regulator cause it looked caroded but still dies.
