Usually the underbonnet fuse board, I suggest you get a replacement and try that. Also check the main power leads around the battery itself, they rot completely through sometimes.

Renaults are notorious for loom corrosion around the battery tray, it's usually only discovered after the car won't start and requires careful examination of the loom, the corrosion can be inside the insulation. A code reading session could help.
