The best way to go about rewiring a boat. '97 Baja 272 Islander

I did what some suggested and ran a separate power and ground from my battery switch up to the helm with bus bar connections for all the accessories. This was to give things like the lights and stereo a cleaner, separate power source and hopefully eliminate the "gauge jump" when lights are turned on/off or blowers are kicked on. Alas, it still did not eliminate my problem.
