Yes the rectifier diodes issue unfortunately is all too common due to the
mean-ness of manufacturers to use components that can stand the surge
currents involved at switch on. Fuseholders, well many are pone to
corrosion as they are often just crimped together between the springy holder
bit and the pins that go in the board. I've even come across actual fuses
that look intact but the internal connections have corroded making it an
insulator most of the time.
The other vulnerable piece is often the plugs on the end of the wire that
go into the devices being charged.

Managed to get both chargers working courtesey of this NG.

Charger 1 required a new fuse holder & fuse, old fuse holder wasnt giving
continuity.

Charger 2 replaced the faulty diode as advised and now working, stopped
blowing fuses now.

I put both on the mobile scooter for a couple of hours each and no
problems.

I initially thought my odds were very low to get any of them working due
to lack of electronic knowledge, so pleased they are now both working.

Thanks all.
