Question type: Maintenance & Repair
We have a brand new battery and a brand new alternator and it's still not
staying charged. I can only go 2 miles all the lights come on and my gauges go
crazy then my truck dies. We will jump it and it will start back up.

Check fuse 11 (alternator field) i believe. At 12 volts you are just running off your battery. Just had the same problem with my 2002 F150 SuperCrew
