When starting the vehicle the electricity surges my truck stalls then starts back up when idling, but when the vehicle is in motion the lights flicker. I bought a brand new battery but that didn't fix it.

Good morning,

Can you please measure the voltage at the battery with the engine running with a voltmeter and tell me the voltage?

Let us see what the alternator is doing with charging the battery.
