This is my 3rd CMM1200 charger, part number ETPCA-p240120U.
They keep dying on me. Left out in the rain? Dropped? Either way, I don't want to keep dropping $40 every 8 months.

So I cut mine apart. See 2 attached photos. Thought maybe it was just the LED dead, but voltmeter shows no voltage on any pair of the three pins on the connector.
The internal circuit board has part number IBO85373R or maybe IB085373R (O or zero, cant tell)
but googling for that came up empty.

Does anybody know why these chargers keep dying, how to prevent them dying, or if there's an alternative charger?
