Running Nav. Lights & Fishfinder From 12v. Battery.?
I have a 2005 manual (pull start) Mercury commercial outboard motor. Is there anyway I can charge a battery from this, not to run an elect. start on the motor but to run a fish-finder & nav. lights? Is it worth it or do the lights & fish-finder use so little power that I can run them straight off a pre-charged battery without worrying about the battery running dead? .
