Need to know which fuse is still blowing.
As for the radio, there are two models with a 100 percent failure rate. The cassette version is model number 56038518. The cd player ends with a "67". The circuit that fails is the microprocessor "reset" circuit. It only functions for a fraction of a second when power is first applied to set the microprocessor to its starting point. After that, the circuit can fail, which it may have done in your case, and you will never know it until the battery goes dead or is disconnected. Failure of these models is usually attributed incorrectly to the mechanic working on the car or replacing the battery.
Your radio likely failed a long time ago, but the failure didn't show up until the battery went dead, but it is also possible for a fuse to be blown. There are two; one is labeled "radio" that turns it on when you turn on the ignition switch. The other one is for the station presets and clock memory. That one will be tied to another circuit that is always hot, such as the horn or interior lights. Chrysler original radios have a lot of safeguards built in including diodes that will safely short out jumping or installing a battery with reverse polarity. The fuses will blow preventing any further damage. Many of those safeguards are missing from inexpensive aftermarket radios.
