I seen a 1970 Ford Mustang run while taking the battery out, but they had to keep feathering the gas. There are still ground circuits to complete the different circuits, but I would not leave a battery disconnected for very long as it would be hard on the alternator.

DON'T do that!! Disconnecting the battery with the engine running creates a huge voltage spike that can easily fry the electronics of a modern vehicle! HTH. -Jim


no you cant the computer needs 9.6 volts to keep it powered


I wasn't thinking on how far we have come from the "70s" Thanks for having my back!

You're welcome. Glad to help. Speaking of the '70s, I once did this very thing to my 1970 Pontiac Catalina and successfully burned out every light bulb in the car when I switched on the headlights!! -Jim


Well (chuckle) , the question was whether or not if the car would stay running. Thank you again, I was not thinking of the outcome of doing this...


i don't think your volts would spike at all


Why don't you try it and let us know what happens?
