At the end of August my battery of my 2004 Outlander 330 has blown up due to not being put in correctly and it had fallen of and leaked acid. Some Rear wires have been burnt and I'm wondering the difficulty and price to fix

 

No one can tell you what it would cost but a dealer or repair shop.If you want to try it yourself,just invest in a cheap 5 buck service manual. The wiring schematic would help on repair and any other problems you may have.2004 Bombardier Outlander 330 HO 4x4 Service Manual PDF Download
