Recently purchased a 2001 Pro team 185 and Im having a problem I hope someone can answer. I installed a front fishfinder a month ago and I recently noticed a ticking sound coming from the top of my trolling motor when I turn on my front fishfinder. Im certain its wired correctly, including the ground wire. When I got on the water this morning I noticed my boat cranking as if the cranking battery was going dead. Later that day my buddy in the back of the boat noticed a ticking noise. After further inspection I realized we would only here the tick when the rear fishfinder was on. I think this is the reason my cranking battery is draining. What is this problem? This boat is killing me! First it leaked, now this. HELP!!!!!!!!!!
