It lives! Ahahahahahaha!!!

Admittedly, I did have to bribe it with a new battery...

 

Is this the Z200 with the battery that "no amount of charging will bring
it back from the dead"?

I cannot tell a lie. Actually, it's sort of undead atm - I could charge it
up to over 12 volts, but it would slip back once the charging stopped. It's
been sitting happily at about 9.5 for the last week.

 

I assume you're testing it with a multimeter? Test it with a load (a
headlamp bulb or some such), then see.

It's fucked. I suggest fixing wires to the terminals and lick them. To
see what happens.

 

....even sat in the garage )

If he is testing it with a multimeter and all he can see is 9.5V he
don't need to go any further than his local battery emporium for a
battery with 6 rather than the apparent 4 working cells he has already
got.

 

Already done that: brown stain on the back of the garage door.

No, no, I'm sure it's salvageable, just needs a really aggressive boost.
Time to crank up Old Sparky...
