I would trace out the wires and make sure there is nothing else hooked up to them and inspect for damage. How many watts is the inverter you are running. There are a few things you can do to isolate the 2nd battery from the first to allow your truck to start even if the 2nd battery dies, depends on the invertor size what method to use.
