re: F150 mechanical help needed.

It blew the fuses to the trailer. As soon as I hooked up the charger the headlights flashed on then off. I let the charger charge then started the truck cut lights on then it blew the fuses. Fuel gage wasn't working and check engine light was on. Unhooked battery after I let it charge and check engine light went off but wrench light came on. Truck is just lugging down bad. No power
