Boat Info
1995 Sea Ray 400 Express
Engines
7.4 Mercruisers
Need manuals and info on battery banks. My stbd batteries run dead. One is new. Other unknown. Just bought boat. Thanks
 
Can't help with manuals, but best thing you can do is replaces all batteries now. Then you will have a starting point. 90% of electrical issues on boats start with the batteries.
 
Check the water level. And plan on replacing the battery charger. My new to me boat was cooking the batteries. Water was low. They wouldn’t hold a charge. And eventually exploded on me.
 
Before replacing anything I would load test your batteries,
Test your charger to see if it’s working, then check output on alternator. I’m not a fan of replacing parts until you fix a problem.
