I have been having problems with my GPS (Zeus T8) and Autopilot (EV-100) since I installed them last year. The T8 periodically starts activating the touch screen and beeping away like I am tapping away on it. This correlates with nothing I have noticed. Yesterday it did not do it under battery power during a race, but started when I started the engine. I am 95% sure that it has happened without the engine running as well. The Raymarine periodically freezes while in Autopilot mode. This also happens with or without the engine. A B&G tech support guy I talked to thinks the problems are related in some way to the network (Seatalk NG/NMEA) or the power. Yesterday, I detached the network cable from the B&G when it started beeping and continued to beep away. So that leaves power. Today, I checked the voltage being supplied to the T8. The batteries had not been topped up since a race the day before and were reading about 12.5-12.6 volts (AGM). At the GPS power cable, I measured 12.2 (one battery)-12.3 volts (both batteries). Does that voltage drop make any sense and is that 0.3 volts potentially relevant to the problems? Dave
