[ICOM] IC-2SAT help needed

[Gary Fiber]

Reed,

Most likely its the DC Jack causing the problem or a missing ground. The DC 
jack is also a switch that connects or disconnects the battery. Many times 
the little leaf breaks off from use and the battery never is reconnected. 
Another thing that used to happen was when you applied power you might drag 
the power connector across the DC Jack and touch the ear phone jack. This 
would cause a ground trace under the DC jack to open and you would not 
operate from battery. Lastly the PRT unit, about all I remember with that 
was recharging troubles, have not looked at one for a while, bit it does 
have an effect upon battery operation. During my time supporting the 2SAT 
this trouble was almost always one of the first 2 problems.

A quick test was to do an ohmmeter check between the Negative and "E" 
terminal on the radio bottom with no connector inserted into the DC Jack. 
The ohmmeter should show a short. When there is a connector inserted into 
the DC Jack the ohmmeter will show open or more ohms than with the DC Jack 
being unused.
