Have three MH-C9000 chargers and the two oldest have developed one slot each that thinks there's a battery inserted (when there's not) as soon as it completes its power on self-test. Those slots then begin charging at 125 mA and show a small fraction of a volt which, of course, effectively turns my 4-slot chargers into 3-slot chargers. Inserting an actual battery into those slots has no effect at all, they still continue to try to charge at the 125 mA rate and never show the real battery voltage, just that initial fractional voltage. Has anyone seen this before and have any idea which component or components might be causing it? Since those slots are now useless for charging batteries, if someone knows what parts need to be replaced to repair them, I figure I have nothing to lose by trying. Thanks for any help and/or perhaps a schematic, if one exists.
