Had an issue with my jaguar xf 09. It started with interior lights turning on and off. Then a week later had to jump start the car for 3 days every morning. Took battery to get recharged as it was only 2 years old. Installed it and and car was fine for a day. Then notice headlights, taillights and interior lights and screen on car were on that night when parked and car was off so disconnect battery and tried to jumpstart next morning with no look but after 20 mins of just trying to jumpstart car turns on but it started like it didn't want to start but has not started since. I was given a new battery but no luck as soon as I connect the battery headlights, interior and backlights turn on and car wont start. There was some water coming in from trunk and dripping on trunk fuse box. Replaced fusebox and same issue but notice some corrosion on a connector will try to post pictures. Any advice with the crazy electric issues. Is the corrosion in the that one connector causing all those issues mentioned? Thank you in advance
