Welcome,
I will be happy to assist you. If you have a question or need clarification please post back at any time.
The dash and accessories with the exception of the gauges should be running directly from the battery.
The engine, tach, gauges etc. should be running from the engine which also goes to the battery. The only things that should be in common are the battery(s), and battery switch.
Check all of the battery cables for corrosion particularly in the cable. Any discoloration of the cables indicates corrosion. If this is a salt water boat I would replace the battery cables.
Check the grounds particularly on the engine and any that tie the two batteries together. If you use a removable battery terminal to attach the cables replace it.
I think from what you have posted you have a cable/wiring problem, not an engine or accessory problem.
Please post back your results and any questions.
Jeff
