Update:
So fuse arrived today, soldered in to the charger, switched on and POP!
That will be for the bin then as now beyond my understanding of electronics.
At least it never exploded this time.

Ok now waiting on replacement fuse & holder for the other charger,
fingers crossed.

worth replacing the 4 mains diodes if you know how, those are the most likely cause.

I have taken out the doide that reads faulty.

Have you tested it again out of circuit OOI? I ask just in case
something else around the diode was giving you that reading (although
it is unlikely).

I assume its a straight
forward order, its a IN5399 any other rating to consider for ordering.

Nope, that should do it. ;-)

Is it worth replacing any other parts at this stage?

Whilst not necessarily related but I might be tempted to change all 4
diodes once I was there.

I will replace the
fuse again.

I think you will have to. ;-)
