Default Fish Finder wiring

I have just installed a new Furuno 600l on my boat. When we installed it I just spliced into the connection from the previous ff(raymarine). While out today I noticed every time I hit a switch(livewell/washdown pump, bilge, accessories, etc) the Furuno would beep, cut off and come back on. ALso I had a battery drain down as well(not sure if was fully charged to start with though and I am now charging it) and this was with only a few hours fishing(4-5) and running ff while anchored. Does anyone have any suggestions and/or do I need to wire it straight to the battery?
thanks

sounds like you got a short in the wiring to me.

You may want to double check your work.

From the description of the problem, it sounds like you have a poor connection somewhere. Since you spliced into old wiring, could the splice be restricting current? Could the old wiring be weak and need replacement? Is is just something as simple as a loose connection of a ring terminal to a connector somewhere?

I had a similar problem. My GPS would reboot when I cranked my engine. As it worked out, I simply had too small of a master ground lead to my instrument and control bus bar behind the helm. I added an 8 ga ground wire from the battery to the bus bar, and the problem was solved.

Your battery voltage is dropping, which in turn causes the ff to drop out. It could be a loose or corroded connection at the battery. Could also be the battery is givin up. Charge the battery, clean and tighten the connections , and try again. If the problem persists, I would replace the battery.

old fishermen never die, they just smell that way

thanks for all the suggestions. I think I am going to wire all of my electronics to my spare battery and I have room for a 3rd battery and I will probaly ad that just to be on the safe side.
thanks again and I am sure I will have another problem or 2 before long.
