Question about 2004 Mitsubishi Endeavor
The reverse polarity will have "zapped the radio"
There is a possibility that only the supply fuse has "blown", but depending on the radio make, could have blown the internal fuse as well.
Also, there is again the distinct possibility that other supply circuits failed with this Reverse polarity energy supply.
Work across each supply circuit in turn, now the Battery is connected properly.
Ignition warning lights, gauges etc.
Headlights, Turn signals.
Remote locking, Alarm.
Engine startup, Alternator charge output.
A/c operationand Heater/Blower controls, and function.
Best of luck.
