Thanks Doug.
I fired it up this morning, after shortening the cable last nite, and I feel like I did it some good, because it did the complete search at 12.1 volts under load of tv, sat rec, and dome search. This is not battery voltage. The volt meter is connected into the entertainment center, same place as the Dome power lead is, and about 15 ft from the batteries, thru twin lead 8ga wire. When it quit searching, voltage read 12.3. Another volt meter at the 12v DC center was reading 12,5, about 10 ft from batts, but w/ heavier.....2 ga? cable.
Isn't there such a thing as a wad of DC wire setting up resistence, there by loosing voltage ? At any rate, I feel like I'm getting more voltage to the dome now,.....it sounds better too.
I'm glad the dome searching twice may be operating correctly looking at 2 sats to toggle between.
Thanks for your thoughts.
