I can't figure out what's going on with my pickup, the battery started dying on me a couple months ago and i swapped it out and it was ok for a while, then i replaced the plunger and contacts on the starter solenoid which helped then i stopped driving it for a while cause it kept dying and 3 days ago i put in a new alternator and a second battery and it still keeps dying and i don't know what the next move is... any advice would be greatly appreciated. thanks guys.
