Accesory power issues

[Ace14]

I just bought an Ebbtide deckboat and have had it out a couple times now. It has two batteries on a switch and I have replaced both along with all the connections as some had mild corrosion on them. The boat cranks fine everytime. When I turn on the blower or the bilge pump, or the radio etc they work if I am just parked and there is no movement. If I literally get out of the seat or rock the boat then they cut in and out. Stereo resets and turns off etc. I'm assuming it is a ground issue somewhere but not sure where to start?

Start tracing wires, look for the loose connection. It doesn't have to be a ground issue, it could also be the hot side. Did the problem exist before you replaced the battery and switch? Why did you replace the battery and switch?

Batteries were from 2016 and the ends had some corrosion on them so I just wanted to be sure they were new. I believe I found the issue...under the dash there appears to have been some exposed wiring that when the boat was moving was bouncing up and down touching metal or something. Once I cleaned that up a little, everything appeared to be working without the power fluctuations.

Thanks
