General Fishing Tips / Navigation lights and battery system
« on: June 13, 2009, 10:35:04 AM »
A few folks have expressed interest in seeing how I rigged my fish-n-dive for navigation lights. I used standard equipment for a small boat. I got it from Bass-pro and spent about $150 for the parts, wiring, battery and charger for the battery. The wiring is standard marine romex-type wire from home depot with silicon stuffed marine wire nuts for most connections. The power cables for the bow and stern lights were run together with a T off to where it joins with the power cable for the fish finder. Both have independent fuses and join together into one connector for each side of the battery. The battery is a computer system back up battery and weighs about 4 pounds. I can run the fish finder, with backlighting, and the navigation lights for at least 8 hours. I have been using the same battery for almost 10 years now and it still lasts all day. I don't remember where i bought it, but the batery was only about $30 bucks and the charge was a little more than that. I put a switch in line for the lights so that I can turn the lights on and off without disrupting the power to the fish finder. I used a trolling motor puck transducer and epoxied it to the inside of the hull, it has also stayed in place for almost 10 years. roughing up the spot where you will put it and resting a weight on the transducer while the epoxy dries makes for a good seal and pushes out any air bubbles in the epoxy, which is critical for good sonar readings. I found a zip up lunch bag which fits the battery and i just strap it to a scupper post in the hold of the kayak with a bungie. Doesn't move and again, has worked well for almost 10 years. During that time, I have had to clean the contacts in the fuse holders and replace the connectors to the battery every few years because of corrosion, but other than that, no problems. Let me know if you have any more questions, lots of pics below.
