I'm not sure. If the part number of the IC wasn't ground off, you could look up the datasheet for it and see what purpose/effect any support components would have.

I can't quite make out the color code to know what the exact resistor value should be, and you shouldn't measure it while in the circuit because other components could affect the reading. But once you figure out the default resistor value (looks to be under 1k), you can replace it with a pot and adjust it until it matches the exact value as found on the color code on the resistor. But again, if it's not part of the charging circuit, it will have little or no effect on the output. It's all a shot in the dark at this point.
