Battery drain with kicker in This Old Boat Posted Tuesday at 10:55 AM The small alternators on kickers don’t keep up with the draw used trolling especially with high speed riggers. What position is your battery switch in? Best bet is to run 1 or 2 position not in “both”. When you run “both” the weaker battery draws down the better battery. Also how old are your batteries? I’ve had older batteries that load test as good when fully charged, but then discharge quickly. 3 years is roughly the life expectancy of a battery. Your Honda should have an alternator. I had a Honda and the alternator output feed was an option sold separately. So check your wiring to see if it has been wired in to your electrical system. With fully charged batteries, you should be able to run all day on a single battery with your second battery as a backup. Between trips charge the battery. My next kicker will have a larger alternator for sure.
