As I was dialing in my dish the Digital Elevation Sensor lost power. I had never change the battery so I replaced the old battery with a new 9 volt. Now I get an odd indication in the readout "bd" or at least that's what digital readout resembles. I removed the new battery and put the old battery back in and it had just enough power to reflect the correct angle of the dish before it went blank again. I checked both battery's the old battery registered 6.9 volts and the new battery was 9.2. It seems odd that the old battery has just enough power to power the digital readout momentarily providing the correct number and the new battery gives that odd reading which looks like "bd".
Could you provide any troubleshooting ideas?
