All my batteries are relatively new. One of my acessory batteries is brand new. I was running yesterday and lost power to my GPS, VHF and Stereo. I noticed the cabin lights were very dim. I tried switching the accesories switch from 1 to 2. Cabin lights brightened right up but still no power to the above accesories. Shouldn't I have power to these when the engines are running? I'm assuming the guy who wired in the accessories put them on the same circuit and I'm wondering if I should be looking for an inline fuse somewhere. My boat is a 1992 Marlin.
What are the trouble shooting steps to find the problem?
