No power to anything

Alright I discovered that my battery charger was actually broken and reading improperly. I swapped out chargers and I now have power to the truck. I'm not able to get it started though. It'll crank once then click. I took out the starter and had it tested today (looks to be the original). It tested just fine. I was able to confirm 12.65v coming from the battery to the starter.

You may get the voltage, but not enough supply. Try doing a voltage drop test. If there is corrosion in the cable insulation, you will lose current and possibly cause your issue. They also have had ignition switch connector issues- there is a wiring kit available through the dealer due to these burning up. Drop the lower steering column cover and you will be able to see the connector. Any melting of the feed wires- definitely replace
