Wrong voltage display

[JEAN-FRANCOIS MENARD-3]

A friend of mine here, who does not have an Internet access, have a  
basic K2 that show only 5V on the display instead of 12.X or 13X  
Volts. He does not have the battery option. But everything is working  
fine, TX, RX, etc.. The K2 is powered on a good 13.8V Motorola power  
supply.... His jumper on the control board is set to 12V, but the  
display always show 5V and he also get a "low batt" message at every  
couple of minutes....

Where he should look ???

One place is R9 and R10 on the control board -- make sure they are the
correct values.
