so i have a 91 ford f150 6 cylinder 5.0l engine. i just put a new battery in the truck, and the battery is fully charged. but the battery level gauge in the dash is telling me it is getting almost no power. when i turn the key the solenoid on the wheel well clicks a little, then starts to fade quickly. like i do not have enough power. and the truck dose not crank over. even when i try to jump start it, it will not start up. i have already checked my battery connections. and even the connections to the solenoid. i checked all fuses, and all the wires that i could find. that have a snap in connection to make sure they were firmly connected. none of anything i tired did anything. any ideas?

Use a digital multimeter and do a voltage drop test on your cables. also make sure your ground is good. Quick test for that is to hook a jumper cable end to battery negative and the other end to a shiny piece of your engine. If the truck starts or your situation improves you know you are dealing with a bad ground. You will also want to see what your battery voltage is at when you are trying to start it using a multimeter on the battery terminals. When this is happening, do your headlights seem to be bright? Do they dim considerably when you try to start it?
