The three prime reasons for flat batteries on diesel 75s are Satnav, FBH, and possibly wipers spontaneously activating.
Disconnect the satnav (if fitted), and FBH.
Place tissue paper flat under the wiper blades, and IF the wipers do spontaneously activate, the tissue paper should crumple up.
When reconnecting a battery, make sure that the bottom of the battery terminal sits flush on the battery. If not, loosen bolt, gently tap down on the terminal until it DOES, then tighten the battery terminal reasonably tight.
Not getting the terminal to sit flush before tightening, is probably the prime cause of loose battery terminal.
A loose terminal, combined with the alternator turning, probably generated the spike that scrambled your IPK. Any thoughts Gurus ?
And the fuse failure is probably either the white/red wire shorting to the engine block, or a temporary short of a connector to the engine block, while looking previously for the fault.
A fresh pair of experienced eyes from a guru (with a T4) may see something you have missed. The IPK fault needs rectifying, as it may lead to another problem.
I'm glad TOAF helped. I think it is an underappreciated tool. Thanks for donating to the club.
Good luck.
