Fishing boat electical accessory problem

by Brandon

I've got a Lund Pro-V fishing boat. It has a new automotive type starting battery. I have no problems starting my 150 Evinrude or my 9.9 Yamaha, however I don't have much for power while I run my accessories, even while either engine is running (they both have alternators). There is a seperate bank of batteries for my electric trolling motor.


About the most the system can handle is running the radio and fish finder. Anything that I turn on after that such as livewell and bilge pumps or navigation lights, the radio and/or fish finder shut down. The connections seem to be good as each accessory runs well on its own. Is this a wiring or fuse problem or a battery problem? Any advice on where to test things next would be greatly appreciated.

Try Running Radio And Fishfinder Straight off the Battery.
