not a resistor, it is the d4 diode, just to the upper left of the battery. hook your meter to the ground connection on the clc board. you should have 3 volts on the anode of d4, this will let you know that the battery and the holder it sits in is ok. if you do not have 3 volts, which is the battery voltage, do not turn off the unit. the cathode side of the d4 diode is the 5 volt supply from the power supply.
