I switched my lights on to brights instead of automatic and I forgot to turn them back overnight and my battery died and needed to jump it, the next thing I knew my pioneer radio wouldn't work, I checked all the fuses and they were fine, I even replaced the fuse that was connected to the radio. What else could it be?? please help!!

On most 12v cars,the #1 cause is a light left on somewhere in the vehicle.#2 cause is a bad diode in the alternator and #3 is a bad battery which self discharges and is usually over 5 years old.
An easy first step is to disconnect the charged battery over night.If it still has a full charge the next morning,after you reconnect it and if the car starts,you can rule out the battery as the culprit.Now,if the battery passed the first test,now we go onto #2 test and disconnect the alternator output wire from the alternator overnight.If the battery still has a full charge the next day we will now know the alternator has a bad diode and will need to be repaired/replaced.If the battery was found to be low on charge the next morning with the alternator disconnected we will now have to go on to test #3 to find the drain in the vehicle. Disconnect the positive battery cable and place a 12v regular bulb type test light between the positive cable and the battery positive post.You should have a bright light on the test light if you have a drain in the vehicle from the battery.(don't worry about a dim light as electronics need a little memory voltage) We are looking only for a bright light.With the key off (as it would be overnight) you are now going to remove one fuse at a time while watching the brightness level of the test light.Take one fuse out, look at the light and if no change in brightness put the fuse back in and on to the next fuse,one by one until you see the light go out or dim.The fuse that dims or removes the bright test light will be the circuit that is draining your battery.Now you have your "battery drain" circuit identified and can inspect/repair the item/items on that circuit.
REMEMBER an open door,trunk or hood may cause a FALSE bright light on your test light because of courtesy light switches and alarm switches so manually close those switches if you need to keep one of the doors or hood/trunk open to gain access to the multiple fuse boxes in many vehicles.
DO NOT TURN ON THE KEY during this test, as all power to the vehicle is now going through the test light and things won't be happy if you do.

Replace the alternator.

First, check your battery, it sounds like your battery runs out of juice if you leave even a small light overnight.
Use jump cable, if you can jump it, it is battery; if it is not, check starter, it is the next suspect. Usually, if starter dies, you can still hear clicking noise in most cases.

The Battery has gone flat. When you tried to jump start it, this did not change the battery state its still flat.
I bet you will get the same code on the scanner if you remove the battery. Take the battery out and charge it with a battery charger overnight, then try it again.

bad dash ground or at battery, check fuses also .

The alternator may charge fine but could drain the battery through a bad diode,have you checked the alt for a bad diode?Disconnect the battery positive cable.Put a regular 12v test light between the battery positive post and the positive battery cable.If the test light is bright you do have a drain,if dim it is OK.A dim light may mean the drain is internal in the battery.If you do have a bright light remove a fuse ,one at a time from the fuse box until the light goes dim.Once dim you have identified the bad circuit.If removing all fuses do not dim the light,disconnect the alt charging wire at the alt,if that dims the light,then you do have a bad diode.DO NOT create a drain(bright light) when checking for the drain by turning on the key or opening a door/trunk etc.
Also,do an overnight battery check by disconnecting the battery overnight,if things are fine the next morning after the battery was disconnected then it is a drain in the vehicle,if the battery is dead even after being disconnected overnight,,then the battery is bad.

If the lights are coming on, WHY would you be looking for a fuse??? If the fuse is blown, the lights ill not work at all!

When you say "the middle of the night" are you saying that hey are coming on when the car is turned off and nobody is near it? or are you saying that they are switching to bright when you are driving?

Please review the following articles and get back with me.

Where's The Fuse?

What Else Could Be Wrong?

if the lights are bright and you hear a clicking and your heat blows good, the head lights are still real bright after trying to start a few time replace the starter (you can try to hit the starter with a hammer otr somthing heavy a few times and then try to start if it sounds better or starts replace the starter) if the battery goes dead try to jumpit if it starts then dies after a few min its the alt if it starts runs good and you let it run for about half hour shut it off and it wont restart rite away its the battery.

Apparently the 03 wranglers have a tendency to have faulty fog light switches. It might be that your fog light switch is broken and they stay on all the time, and drain the battery. I just had this happen to me and realized after jumping it twice, that my fog lights won't turn off. Hope this helps

if you turn off the switch for the interior lights,an override,it will prevent the battery from going dead until you can get the door alignment or switch repaired.the interior lights,there is more than 5 will kill the battery for sure.
