This is a charger for some fairly new Motorola walkie-talkies. It is supposed to charge two radios at onces, but only one side has voltage. They ahve been put away since last summer when I think my daughter spilled some soda on it up in Yellowstone.













In the second to the last photo I see something on the circuit board. Any advice? How to clean? How to check any of the components/transistors/resistors?
