will not start only clicks once at inside fuse panel

Hello, you are stating that the battery is charged. What testing has been performed to indicate that the battery is able to accept a load? You can have 12.5 V output showing from the battery but it may not have enough amperage to actually do anything. Besides that, the starter motor could have a concern, and can you even confirm the engine turns manually with a breaker bar and socket positioned on the crankshaft?
