Opening the cartridge revealed the problem. The
battery (a solder-tab style
CR2032) was actually good, but the positive terminal 'tab' had come off.
The spot-welds just let go. It must have been poorly made, and then got
dropped at some point. I don't have a replacement battery with solder tabs,
nor do I have a way to get one quickly. But, this seems simple enough, I'll
just solder the tab back on.
I've *never* thought this to be a good idea. I will either get one with the
tabs on it, or put a holder in there, or make some other arrangement...
Lots of the musical gear I used to work on for a living had such batteries in
it. And they needed to be replaced after a while. I'd usually put a holder
in there, if at all possible, and get some happier customers in the
process. :-)
