I upgraded my electronics this past winter and now I have an issue with them turning off when I start the motor. I first figured it was the battery so I replaced it with the largest 31 series battery I could get at my local battery shop. didnt fix the problem so I figure it is probably the wiring. I am guessing an 03 wasnt designed for the current draw of the new electronics and causing a low voltage problem and they shut down. I have a 12" humminbird on the bow and 2-Lowrance HDS 8 at the console all connected to the original wiring that was there. They all run through the main power switch at the console along with everything else in the boat. I noticed Saturday when the livewells are running the problem is worse. The 12 at the bow and 1 of the 8's turned off each time I started the motor.
So has anyone experienced this and how did you fix it? Is anyone running 3 or 4 units like I am on the original wiring and not having an issue in an older boat. I understand the newer boats have alot larger wiring to accomadate in the increased draw of the new electronics
