most older cars will run without the battery connected as long as the alternator is good. i guess its all how its wired.

With one Voltage reg, it stutters but keeps
running. With another voltage reg, it shuts down immediately. What's up with up that?


when the truck shuts down, that voltage regulator must be bad. the truck is just running off the battery, and when you disconnect it, it dies. obviously.
