Toyota Repair: reversed polarity on 98 Toyota RAV4, reversed polarity, toyota rav4

Question
Model: 1998 Toyota Rav4 . Automatic, 2.2 Cy
I have accidently reversed the polarity during the battery replacement. Now I can only turn on the engine and head light. I cannot even change the gear. All interior electronic all gone. What have I done!!! What should I do now???

Answer
You have blown the fusible links located on the positive battery terminal, look for a black box attached to the positive terminal, remove it from the battery and open it up, inside you will see the part of the link that has melted, you can either replace it or in some cases I have repaired them with a small bridge of solder.
