I'm not sure what my dumb Sears 6 & 12 volt battery charger/starter supply puts out when open..
I'll have to check it sometimes. You've got me curious now. |
I would guess that wall wort was for something else in a higher load and not really a charger or it was failing.
I guess once something fails all bets are off.
