If your battery has died you can give it a jump start again and let it stay connected to the car thats jumping it for a couple of minutes to make sure the battery is able to develop a good charge. Why isnt my alternator charging my battery.
On the other hand if the battery is showing no power when tested with voltmeter then the battery is dead and needs to be replaced with a new one.
The alt is an upgrade as I am running a two battery system. The truck has a new battery. Somewhere there is a bit of logic that checks to see if the alternator is putting out charging voltage and then closes the relay to deliver it to the house batteries.
