No Power Master power switch Lund Boat

[Swanextreme]

I have a Lund 2025 Impact. I just took it out of winterization where the shop, as usual, disconnected the battery terminals. I started the motor no problem, but when I went to turn the Master Power switch on, there was no power to the fish finder, radio, bilge pump, etc. I have checked all connections at the main cranking battery and that’s all good. It was working no problem last season. Am I missing something ? The boat is very new to me and I’m sure there is a fuse block somewhere just don’t know where it is. Thought I would see if a fuse is burned out. Any suggestions ?

Look around the battery and make certain that a smaller gauge red wire than the motor feed is not hanging loose or connected to the negative terminal. Usually there will be a least two wires connected to each battery terminal or possibly three if you are wired for a trolling motor off the starting battery. The largest wire feeds the motor. A smaller one may be fused or connected to a circuit breaker to feed the other stuff. Start working from the battery forward and check for power with a voltmeter or test light until you find the problem. Common type problem and usually an easy job for someone familiar with boat wiring. A little difficult to do for someone new to boating but a good way to get to know your system.

Thank you. Yeah it’s pretty clean in there, all wires connected where they need to be. Will start working forward from battery box. Thanks!

First thought would be missing ground or positive lead on battery. Second would be tripped/failed breaker for main power lead to dash accessories
