1st there must be some reason as to why you are doing this. I don't feel it is ever a good idea to remove the battery cable while the engine is running. But if you must know, your engine can only keep running while it has 12 volts going to certain areas... such as coil and distributor. If it dies when you remove the battery then I would guess that the alternator is not working, which may be why you were testing this in the 1st place. A good test for your alternator is to put a volt meter across the battery and see the volts, then start the engine and see if the volts increase. If they dont and the volts are dropping then the alternator needs to be checked out.
where is fuel shut off switch for Ford Bronco eddy Bauer
Your battery is being drained by a short to ground ,SOMEWHERE. Easiest way to find this out for sure , without a test meter, is to disconnect the Positive battery terminal when you shut down engine. Then see if it starts the next day.
You can either fix the problem or disconnect the battery and re connect it
I have a 1995 Ford Explorer , and with the engine running a mechanic disconnected both battery cables and it kept running - I was surprised!
alternator bad
disconnect the battery to shut off/reset
Behind the kicker panel on the passenger side
Replace the ECM.
Hit it with a hammer...or disconnect the wires and reconnect them
A 1976 Ford Bronco would still have a carburetor for the engine , so it does not have a fuel pump shut off switch ( inertia switch ) like the Ford fuel injected engines do ( that use an electric fuel pump ) * if that is what you mean
disconnect positive battery cable for five minutes.
No it shouldn't, but don't try it, as it can cause a surge a fry expensive electronics.
