This was a great buy until it stopped starting, and im not totally sure why. I took my starter and alternator out and had them checked at advanced auto (both tested fine), and i got my battery tested as well, and it was fully charged and in good condition. Would this be an ignition switch? When i put everything back in, i heard the starter try, and it cut out immidiately, and i lost power to the cab. Any ideas?

What you want to do is follow your main power wires from the battery to the starter and up to the distribution block on the firewall then to the fuse block connector you can see on the firewall on the engine bay side. make sure everything is tight, check for 12v on both sides of the distribution block and triple check the driver side of the distribution block when your power cuts out the cab and report back
