Alternator is not charging, to test, start engine And remove battery positive cable, if engine dies sure sign of alternator not charging. Replace alternator.
I would have the battery checked to see if it is not the problem first. If it isn't working right you either need to pour water into the battery cells or just go out and buy another one.

I think there should be another fuse for the dash lights and radio and dome (or interior or courtesy it may be designated). Recheck all of those fuses under the dash, I believe one has blown out. This is when a wiring diagram comes in handy-you can see the fuse lay-out, and what circuits each one serves.
that's becasue the new abattery went dead because it was not charging. The battery light must be OFF to charge the battery. Take it back to whoever fixed it. May be a bad wire betwen battery & alternator too.
check the 175 amp mega fuse in the engine compartment.

check the 20 amp fuse for the charging system. Fuse 26 in teh engine compartment fuse box.
ALTERNATOR IS PCM CONTROLLED BESURE ERASE FAULT CODE.CHECK TO SEE IF POWER GOING TO ALTERNATOR BATTERY FEED WIRE.AND CHECK VOLTAGE REGULATOR WIRES FOR DAMAGE.CHECK BATTERY CABLES MAKE SURE THEY ARE CLEAN AND TIGHT.CHECK THE LARGE MEGA FUSE NEAR THE BATTERY.THAT WILL CAUSE CHARGING PROBLEM IF MEGA FUSE IS BLOWN.
Take the negative cable off and put a test light between the cable end and the battery post. If the light lights you have something staying on in the car draining the battery. Then you have to use the process of elimination to find the problem. Could be dome light, glove box light or anything electrical. You can get a start on finding the problem by pulling one fuse at a time and rechecking. If a fuse causes the light not to light than that cicuit is the problem. This can be a long process so just take your time and stay calm. Good luck.
