I think 11.7V should be enough to run that unit. No power hierarchy going on. The wire won't have anything to do with it either. 10.7 V is the majic number on my Lowrance units, I think. Can't say what the Eagle FM 480 is, but as a Lowrance product, I would suspect the same.

I would turn on the GPS, and go to the data screen that shows voltage. The turn on the 480, and see what that voltage reading on the GPS does. If your battery is good, I suspect it will stay rock solid. If it cannot tolerate additional load, the reading will dip trying to start the 480. A fully charged, good battery should read 12.6 volts. Also, if your alternating on the motor is working, that should take the voltage reading to about 13.5-14.5 volts. Assuming a good battery.

Maybe the 480 took a dump? Bummer if it did.
