Puma maxi fuse FL1

Hi,

First post here and really hoping you all can help…

Driving yesterday, car just cut out. Ignition came straight back on and away we went. 10 minutes later it stopped again, this time dead. The 60amp maxi fuse, FL1 had blown. I swapped it out to get us away (we’re on holiday) and it’s been fine since, done 30 miles or so.
I’ve had a good look through the wiring and there’s nothing obviously shorting out on the tub or engine.
Has anyone blown this fuse and if so any pointers? Got 300 miles to drive tomorrow and I’m nervous!

TIA, Rob

What car/engine is this ?

Defender Puma, 2012, 2.2.

Ah, sorry I have the no electonics 1994 300tdi version.
I'm a bit lost with these new fangled ones.
