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.

Gdgd. Coincidentally I lifted the two brand new batteries out of what
was Dads scooter (that Mum is now hanging onto for a visiting oldie
and herself in the future) and the first one I've put on the Optimate2
doesn't look very good. Had I been able to get a mating connector for
the plug on the battery case I'd have put them on two chargers and a
monthly charge up before now. ;-(

Well done for both doing it and not giving up on the one that was in
the bin. ;-)

I just got a "battery desulphator" to have a play with some knackered
wheelchair batteries - will be interesting to see if it has any effect
at all.

And I would be interested to hear as well Rob. ;-)

I put the Optimate 2 on one of the 2 x 12V 22Ah gel batteries and I
also stuck one of the basic Aldi battery condition meters (an LED
voltmeter).

It's currently going between all LEDs off (sub 11.5V I think) to all
LEDs on (15V) as I think the charger is pulse charging the battery as
a form of de sulphation phase?

I may put the Optimate4 on the other battery as I think it's a bit
more sophisticated (and that battery is reading about 3.5V so I don't
have much hope for either of them).

You're welcome. It's odd how the Law of Sod works in so many mysterious
ways. You can be thankful that the diode sacrificed itself to save the
rest of the HT module from harm. :-)

Good feeling innit.

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.
