T&T: Autopilot help needed

[David&Joan]

Robert:

Perhaps one of two things:

1. The various motors are pulling the DC voltage down below the Simrad's 
drop out point.

2. RF created by the various motors is interfering with the Simrad.

I would bet on 1. The DC dropout voltage may be software adjustable. Check 
out the docs. If not it sounds like it is defective unless you have a very 
bad battery. Those small motors shouldn't pull down you DC battery. It 
shouldn't drop out until the batteries get down to 10.5 volts.
